The Karkinos (kark-EE-nohs) is one of the Species in the Aberration-DLC of ARK: Survival Evolved. It is useful for picking up wild animals and carrying them to a taming pen, as well as general combat usage or a source of Organic Polymer.

Dossier[edit | edit source]

This dossier section is intended to be an exact copy of what the survivor Helena, the author of the dossiers has written. There may be some discrepancies between this text and the in-game creatures.


Karkinos Versatus is the giant cousin of modern crab species, with long, spindly limbs that remind me of the Japanese Spider Crab and a hard, stony shell. It is much more agile than its smaller brethren, but even more noticeable are its pincer claws.

In an extraordinary display of dexterity, Karkinos is able to wield each claw independently and precisely. This allows it to trap multiple targets in its vice like grip, or hold an enemy in one claw while it smashes a second foe with the other.


Many survivors have found Karkinos to be an excellent war steed, as it can snatch enemy riders from their mounts, or grab and throw smaller creatures. However, its ability to leap to great heights and its swiftness relative to its size also make it useful in caravans.

~ Helena

Behavior[edit | edit source]

The Karkinos wanders the waters of Aberration and is aggressive toward land-based creatures, and given its large size, it can prey on much bigger predators than most of the other aquatic species. Surprisingly despite its size, Karkinos can also be found in the rivers of artifact caves.

Appearance[edit | edit source]

The Karkinos is a large amalgamation of various arthropods, most noticeably the spider crab, having 5 elongated pairs of limbs and 1 pair of stunted legs between the 2nd and 4th pair of legs. The legs are almost skeleton-like, spanning a huge distance from the central abdomen. The head appears to be similar to that of a harvestman's with fearsome chelicerae(mouthparts). The most unusual feature is the two, huge pairs of claws along with an extra pair that is placed above the head.

Color Scheme and Regions[edit | edit source]

This section displays the Karkinos's natural colors and regions. For demonstration, the regions below are colored red over an albino Karkinos. The colored squares shown underneath each region's description are the colors that the Karkinos will randomly spawn with to provide an overall range of its natural color scheme. Hover your cursor over a color to display its name and ID.

Server admins can use this region information in the Console Command "cheat SetTargetDinoColor <ColorRegion> <ColorID>".
For example, "cheat SetTargetDinoColor 0 6" would color the Karkinos's "body main" magenta.

Wild Stats Level-up

Type in values of a wild creature to see on which stats it's emphasized. Green values on a high-level creature are very good for breeding. If you have already tamed your creature you can try to recover the breeding-stats with an external tool.[1]


The stat-calculator does not work in the mobile-view, see here for alternatives: Apps

Note that after the creature is tamed it gets bonuses on some stats depending on the taming effectiveness. This makes it hard to retrieve the levels on a tamed creature, so this tool is only for wild ones, but gives a first impression, how well the stats are distributed.

Combat[edit | edit source]

This section describes how to fight against the Karkinos.

General[edit | edit source]

The Karkinos attempts to grapple you and repeatedly slam you into the ground.

Strategy[edit | edit source]

Stay away from the front of the creature, as it can pick you up and immobilize you as it turns you into a tasty snack. Underneath its belly or directly behind it are the best positions to maintain. Try to attack the legs. Spinos are generally the best dino to attack it with, since it cannot lift you off of a Spinosaurus.

If you do not have a large enough dinosaur to combat the Karkinos directly, it's better to utilize a crossbow or a compound bow with metal arrows from a ledge that it can not reach over. Don't waste your ammo with guns such as the Longneck Rifle or Shotgun; the Karkinos takes significantly reduced damage from guns, but takes normal damage from arrows. (This trait passes over to tamed Karkinos as well.)

Weaponry[edit | edit source]

Avoid utilizing early primitive weapons such as Bow and Slingshot (it will take a very long time). They do little to no damage towards the creature, even if struck through the limbs.

Dangers[edit | edit source]

They often roam the water, and can make fishing a dangerous task. In addition to this, their attacks can hold you underwater and cause you to drown.

Regardless of the dino you are mounted on (except large dinos such as Rock Drake, Reaper and Spino), Karkinos may attempt to grab you off the mount. Unless whistled to attack immediately or using Whip, it is a guaranteed death to whoever gets grabbed on its claws as it will never release the grabbed beast/survivor from its claws unlike Megalosaurus unless it has sustained a lot of health loss that forces its grasp off or if you flash/stun it by using a Plant Species Z Fruit.

Weakness[edit | edit source]

The Karkinos has a giant hitbox and a small attack range for its size, leaving them unable to hit a Spinosaurus using properly-timed attacks that can stagger the Karkinos. They are also quite slow so you can kite them around fairly efficiently.

Taming[edit | edit source]

For general infos about domesticating a wild creature see Taming.

KO Strategy[edit | edit source]

Much like a Rock Elemental, Karkinos cannot be knocked out with the traditional arrows, darts or animal torpor attacks; instead requiring weapons like the Catapult Turret or Cannon aimed at the main body. Hitting the limbs instead of the crab's body will deal heavy damage to the creature instead of applying torpor, so aim carefully. A few misplaced shots, especially with the cannon, can easily kill the Karkinos, or render health so low that the taming attempt will have to be abandoned until it recovers. Due to the difficult aiming mechanics of the cannon, and the cost of ammunition, it is recommended to use a catapult turret instead, being both more cost effective and far easier to aim. One catapult shot deals roughly 400 torpor, and with a high rate of fire, the turret can easily outpace the cannon in terms of how quickly torpor is applied.

Paracer Strategy[edit | edit source]

One method of bringing down a Karkinos is placing a Catapult Turret on a platform saddle; the only candidate in Aberration, which just so happens to have the perfect height for this role, is the Paracer. If positioned just behind the rider's seat, the catapult is able to shoot almost directly down behind the Paracer's rear, which is typically where a Karkinos will be if the Paracer is made to face away from it. While attempting this strategy, be sure your Paracer is set to passive, and that the Karkinos is first targeting the Paracer instead of you before dismounting to climb onto the catapult. With careful aiming, a Karkinos can be easily, and safely knocked out from atop your Paracer's back. One of the few drawbacks to this strategy is that Karkinos will often attempt to flee once their torpor reaches a certain point, but a catapult's quick firing rate gives you a decent window to land the knockout before it has the chance to run.

Trap Strategy[edit | edit source]

Building a stone trap out of dinosaur gates or pillars is the most reliable method of taming a Karkinos, despite the resource costs associated with it. Karkinos tend to move around quite a lot, and are quite difficult to aggro onto you. While this presents a challenge either way, building a trap ensures that the Karkinos can't run away at high torpor, or aggro onto another creature. Trapping a Karkinos can also prove difficult, as they are capable of jumping over and out once contained, and trying to shut the trap can easily result in a survivor being grabbed by the crab, causing a swift death. There is the added disadvantage that said traps are stationary, and cannot be moved, sometimes causing you to lure the desired Karkinos over long distances before it can be trapped. If you choose to build a trap, build a three to four wall high tower near to it on which to place the catapult for aiming down. Be aware however that once a Karkinos is closed in, it can behave erratically; turning in all directions as it attacks the enclosure, sometimes making it difficult to land a good shot. A good time to take the shot is when the crab is facing away or towards you, as less limbs get in the way of your strike.

Preferred Food[edit | edit source]

Exceptional Kibble

Utility[edit | edit source]

Although being a bulky creature, it makes up for it with its ability to jump and to pick up medium-sized creatures.

Controls(PC)[edit | edit source]

  • Tap Left or Right: Attack with respective claw (Slam held creature, does not damage held allies)
  • Tap both Left and Right together: Combined claw attack that does more damage than either single claw attack, cannot move while performing this attack.
  • Hold Left or Right: Pickup/Release creature with respective claw
  • C: Throw creatures held in either claw. Can hold to aim and charge for much farther throw.
  • Spacebar: Jump. Can hold to aim and charge for much larger jump. Can repeatedly jump vertically while in the water.

Roles[edit | edit source]

  • Jack of All Trades: Thanks to the Karkinos's numerous attributes, one can use it for a plethora of different tasks without having to specialize levels. The Karkinos is one of the best travel mounts on Aberration, next to the Rock Drake and Reaper, has high weight, good damage and DPS, can grab and carry small-medium/large creatures including humans, jumps far distances, can throw players and creatures, is ignored by most wild predators, is immune to radiation, can walk underwater, has extreme bullet projectile resistance, and can be force fed Spoiled Meat to heal faster than most other carnivores. With all of these abilities and more, a Karkinos can be useful to fill almost any task needed at a moment's notice.
  • Animal transporter: Given the lack of fliers that can carry wild animals to and from different locations, the Karkinos is the Aberrant Ark's best method of transporting animals, and unlike the two other terrestrial carriers, the Kaprosuchus and Megalosaurus, it is able to pick up tamed creatures as well as wild ones. Not only capable of picking up just one, but two creatures at once, the Karkinos can even throw, as well as jump while holding them. This helps to ease the burden of getting creatures across gaps or up cliffs in the rugged terrain of Aberration.
  • Water Exploration: The Karkinos, lacking an Oxygen stat, can survive underwater without needing to surface for a breath, and when it is within deep water, it will sink and walk along the bottom with ease. While submerged, the Karkinos' jumping ability switches from a charged target jump to a straight vertical shot, and can be repeated even without touching the ground. This allows the rider to quickly surface when in need of oxygen, and then quickly sink back to the bottom. While touching the bottom, the rider can dismount, and the Karkinos will not wander off towards the surface in search of land like some other ground based mounts. While there is only so much deep water within the Aberrant Ark, the Karkinos is an excellent choice for aiding in dives for Silica Pearls, and is more than capable of defending itself and its rider during this endeavor.
  • Radiation Zone Explorer: Most animals native to the Aberrant Ark are immune to radiation damage, and can safely explore these zones. The Karkinos however, has a distinct advantage over many of the other mounts that can go within these areas, which is filled with cliffs, high ledges, and many gaps that have to be navigated around. Although slow when it comes to running, with its ability to jump, the Karkinos is just behind the Reaper and Rock Drake when it comes to the ease in which it can navigate these areas.
  • Mobile Taming Pen: With the Karkinos' ability to pick up and hold creatures, coupled with the fact that the rider can wield weapons while on the back of one, the Karkinos is perfect as a mobile taming assist. Provided that the held animal is positioned where it cannot hit the Karkinos, or can only hit occasionally, the rider can easily tranquilize the captured animal from atop the safety of the Karkinos' back.
  • Assistant Harvester: While the Karkinos can really only harvest limited resources from corpses, it can however carry creatures that are able to gather what it cannot. While holding certain gathering animals with auto harvesting enabled, with different creatures yielding different resources, the Karkinos can effectively be used as a lawn mower to gather all kinds of various resources, picking up and moving these harvesters to areas they would have difficulty reaching on their own in Aberration's rocky terrain. Moschops, provided their wandering is also enabled, can be one of the best harvesters for the Karkinos to carry around. Normally only a wandering, autonomous harvester, the Karkinos provides a means of easily guiding this meandering gatherer. Easily capable of harvesting wood, thatch, berries, mushrooms, and fiber, the Karkinos helps to bring out the Moschops' full potential when it comes to its more difficult harvesting capabilities. While they normally flee at the start of combat, a Moschops can be held in place by the Karkinos, and any threats can be dealt with as long as the Karkinos' other claw is free (be careful to not let your Moschops get hurt). Once the threat is dead, the Moschops can be held over or dropped on the dead target, and will at once begin harvesting resources such as regular prime meat and prime fish meat. Depending on the corpse, such as another Karkinos or a Lamprey, the Moschops will even pick up leech blood and organic polymer. Other harvesters, like Ankylosaurus and Doedicurus, can be used to fill in the Moschops' gaps and gather stone, flint, and metal. (Note: While the Doedicurus can harvest stone autonomously, it will only do so up until half of its own weight capacity. The Ankylosaurus must be either ridden by another player or the Karkinos rider can carry the Anklyo to its destination, dismount, mount the Anklyo, harvest the resources, re-mount the Karkinos, and move the Ankylo to the next destination. While this is still more effective than riding the Ankylo around, it is strongly recommended to go with the 2-player approach.)
  • Nameless Venom Farm: Despite being unable to pierce their natural armour without Charge Light like the Basilisk, a decent level Karkinos can farm Nameless Venom quite efficiently due to its ability to pick up creatures. Simply pick up an alpha Nameless with one claw and beat the respawning Nameless with the empty one. Additionally, to prevent reapers from being summoned, swap out the Alpha Nameless with a fresh Nameless and kill the attacking Nameless with your empty claw. As Long as you are under 50% Weight, your Karkinos will automatically pick up the Nameless Venom. Bring a source of Charge Light for when you need to take a break from killing Nameless, such as emptying your inventory or healing your Karkinos. (Level Health And Melee. Weight is also a considerable choice due to the ability to pick up items while under 50%.)
  • Travel: The Karkinos is a huge step up in travel capability progression when compared to the Ravager, Roll Rat, Iguanodon, or Raptor, is akin to the Reaper in mobility, and is second-only to the Rock Drake's gliding and cimbing in travelling. Though its running speed is not all that impressive, it can leap incredible distances with great precision and can literally turn on a dime to make up for that small short coming. Better still, leaping requires little stamina and the Karkinos can even regain stamina while in a leap. As the Aberration map is incredibly vertical with cliffs, ledges, and drop offs, its jumping ability comes in handy as it takes little fall damage and can hop from ledge to ledge to arrive at a desired destination. Its jump can also be useful to escape danger or for chasing an enemy. For the best best mobility possible, pump in Speed, along with a little Stamina.

Notes/Trivia[edit | edit source]

For information pertaining specifically to the real-world Karkinos, see the relevant Wikipedia article

  • The torn dossier for this species was first revealed on November 11, 2017.[2]
  • "Karkinos" is the Greek name for the constellation Cancer.
  • Like the Pulmonoscorpius, Karkinos can be tamed with spoiled meat if the player has no kibble. After taming, spoiled meat provides more Food than raw meat.
  • Tamed Karkinos will automatically eat spoiled meat first regardless of other meats in its inventory, just like Pulmonoscorpius.
  • Karkinos receives 10 points of health per unit of spoiled meat eaten, allowing it to recover health by force-feeding twice as quickly as most tames.
  • Leveling a tamed Karkinos makes it do what appears to be a "crab dance"
  • Whether Karkinos can carry a creature is based off that creature's drag weight; Anything with a drag weight of 250 or below is able to be picked up by the Karkinos. This can sometimes be confusing if two creatures with different drag weights are a similar size in game. For instance, while Stegosaurus and Roll Rats can be carried, Megalosaurus and Triceratops cannot, as their drag weights are 350 and 300, respectively.
  • Be careful when fighting a Sarco in the water, as it can get underneath the Karkinos, causing it to be stuck and unable to fight back.
  • Oddly enough, Karkinos' upper pair of pincer limbs were never used for anything in game other than for aesthetic purposes.
  • "Karkinos Versatus" translate into "Veteran or Experienced Crab"
  • Karkinos is one of the only species where the first part of the species’ name (karkinos), is the common name.
  • The Karkinos appears to have a bug associated with the landing after a jump which rarely results in the game crashing (tested on PC). This can be quite dangerous when travelling in hazardous areas, and should be taken into account when considering its use as a combat mount.
  • Karkinos are one of the three species that can only be knocked out through striking at certain parts of its body with blunt/explosive projectile, others being Rock Elemental and Titanosaur.
  • Unlike most arthropods in the game which tend to bleed green, Karkinos bleeds a light blue colored blood similar to the modern horseshoe crab.
  • Despite being a giant crab, it can't side-step like normal crab usually do. And considering side-stepping is normally faster, the Karkino only knows how to move forward at a moderate pace.
  • Karkinos does not produce feces.
  • Most crabs have gills instead of lungs, which in theory should make it so a realisitic Karkinos would not be able to stay on land for very long without suffocating. However, some real-life crabs and other crustaceans do have exceptional adaptations for respiration on land. Specifically, the Robber Crab(Birgus latro) uses a branchiostegal lung in order to breathe.[3] In fact, an adult Robber Crab will drown when submerged in water, which is quite unlike the Karkinos as they can survive and thrive in water as well as in terrestrial environments.
  • Real crabs lay eggs, however Ark's Karkinos does not.
  • Although the dossier suggests that the Karkinos is an omnivore, in the game it can only consume meat. This could be an oversight of the developers or a misidentification of the Karkinos's diet by Helena Walker herself.
  • Many Real-world Crabs are social animals that live in a group called a cast. If Ark's Karkinos were real, they would live in a cast just like real crabs. probably making them more dangerous than they already are in Ark.
