Basic Info[edit | edit source]
Dossier[edit | edit source]
Castoroides is a large, mammalian herbivore that tends to live near water. Unlike other larger beaver species this one retains the chisel-shaped teeth of modern beavers. As is typical for beavers, they build dams as habitats, but the larger creatures on the island have a tendency to trample them. As a result, finding unsullied dams in the wild is quite rare.
Castoroides itself doesn't seem to realize how dangerous the island is. I don't know if it's simply too dumb to notice the dangers, or if it just doesn't care...but Castoroides happily goes about its day playing in the water and gnawing on wood.
The value of a tamed Castoroides is obvious from its physiology. The creature naturally gathers wood extremely efficiently, far more than most species on the island. It's not the strongest creature, so it can only carry limited amounts, but it is a natural lumberjack!
Behavior[edit | edit source]
Wild Castoroides will build dams containing large quantities of Wood, Cementing Paste, Rare Flower, Rare Mushroom, and Silica Pearls. Giant Beavers are very protective of their dams and will come to their defense should anyone threaten them. One to three beavers have been noted around a dam site. See Giant Beaver Dam for a map of locations. The dams will never be re-filled, be sure to destroy them after looting.
Castoroides will not attack any entity (whether it be player or creature) unless aggravated to do so. Often, Giant Beavers who reside close to swamps will be forced to defend their territory and fight against wandering Dilophosaurs and invading Titanoboas. Sometimes they can be seen grouping up against larger predators like Carnos or swarms of smaller predators like Raptors and Terror Birds. If a player attacks one, the entire Giant Beaver population in the immediate area will attack. Unless injured by the player, a player can get as close as they would like to a Giant Beaver. If the ability to kill a Beaver in a single hit by a powerful mount is available, doing so will not make the other Beavers attack.
Appearance[edit | edit source]
The Castoroides is a giant species of beaver found commonly in the rivers and ponds of the island's interior. It also appears at the Hidden Lake. It has waterproof fur and a flat tail for swimming. With their powerful jaws and sharp incisors they can gnaw through many of the trees found throughout the island, using the resulting wood and other raw materials to construct their dams.
Color Scheme and Regions
This section displays the Castoroides's natural colors and regions. For demonstration, the regions below are colored red over an albino Castoroides. The colored squares shown underneath each region's description are the colors that the Castoroides 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 Castoroides's "body" magenta.
Region 2 is not used
Region 3 is not used

Base Stats and Growth[edit | edit source]
Note that creatures will have different stats in Survival of the Fittest
|Attribute||Amount at Level 1||Increase per point||Taming Bonus|
1Percentages are based on the value of the stat the moment the creature was tamed (after taming effectiveness)
2The absolute Base Damage is shown here instead of the percentage.
3Wild creatures do not level up movement speed
4Torpidity increases every level on wild creatures, but can not be increased once they are tamed.
|Movement Type||Base Speed||Sprinting|
- These are the base speeds of the creature at 100% Movement Speed
- For a comparison of the speeds of all creatures, see Base Creature Speeds
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.
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.
Taming[edit | edit source]
For general infos about domesticating a wild creature see Taming.
KO Strategy[edit | edit source]
The Beavers are not hard to down, as it only takes around 9 tranquilizer darts to down a lvl 75, so just using darts while it's chasing you should work fine. You may also put it in a small taming pen or use Bolas on it. The Beavers torpor drops very rapidly so it is very important to fire tranquilizers in rapid succession and have a lot of narcotics on hand, as the tame is long and slow.

Combat[edit | edit source]
This section describes how to fight against the Castoroides.
General[edit | edit source]
Giant Beavers are actually very tough and deadly animals both in the water and out. They are surprisingly fast, and they do a lot of damage. Beware!
Strategy[edit | edit source]
Staying away and out of water can make the Castoroides an easy dino to knockout along with their decently low torpor, but need a fair amount of narcotics.You can walk backwards to avoid damage, but they will eventually catch up to you. Whatever you do, do not go in the water with an angry Giant Beaver, or it will likely kill you in seconds. If just trying to outright kill it, try using bolas and attacking from the sides or back with melee.
Weaponry[edit | edit source]
Depending on the distance, use any ranged or any melee weapon to kill them. They are vulnerable to Bolas, which can make them an easy kill.
Dangers[edit | edit source]
They are surprisingly fast and capable of killing a Megalodon in a straight biting match. They become aggressive when attacked or their den is ransacked. Beware when looting the dens!
Weakness[edit | edit source]
When unmounted, the beaver will float up to the surface unless they are following you. They cannot climb very well, so height might help a player in trouble.
Utility[edit | edit source]
- Gatherer: Castoroides gather wood very efficiently. Opposed to common logic and due to their weight reduction of harvested materials, Castoroides is a more efficient gatherer and carrier of wood than the Mammoth (considering they both have the same level and none of the stats are buffed). If the player doesn't have a saddle, they can still take advantage of the wood-gathering ability by enabling the Castoroides to wander in a wooded area, as it gathers wood on its own when next to trees. Alternatively, the player can manually lead the Castoroides to trees by whistling for it to follow you to a tree, then whistling it to stop. Almost every time, if the Castoroides is close enough, it will cut down the tree, gathering wood. Simply repeat this over and over, telling it to follow then leading it to a tree and telling it to stop, and you can quickly gather lots of wood with low effort (Level up Weight and Melee Damage).
- Transport: Wood, Thatch, Fiber and Stone weigh less while being carried by the Castoroides. These resources weigh only 50% of their usual value (25, 1, 0.5, and 25 units per 100 pieces respectively). (Level up Weight, Stamina). Where there is the possibility to swim, the Castoroides will travel much faster than sprinting, making the resources travels shorter.
- Organic Craftsman: Once saddled the Castoroides can be used as a Smithy, allowing for a mobile crafting wagon.(Level up Weight).
- Deep Sea Diver: With an oxygen stat but the ability to breathe underwater, raising the oxygen stat also makes swimming faster. Being stronger than a dire wolf, it can defend itself against Megalodons but wouldn't recommend fighting the creatures of the deep unless you have a really good saddle. Due to being a mobile smithy, it is great to go into underwater caves as they usually have resources for most items made in the smithy. However, They will rise up to the surface if you get off of them unless they are following you. (Level up Oxygen, Weight and few points in Melee)
- Resource Duo Strategy: If you have an Argentavis, they become a nice combo for wood gathering, as you can carry the Castoroides with the Argentavis to a dense wood area, clear it out and, as the Castoroides has the weight reduction, you can carry big amounts of resources, then grab it again with the Argentavis back to your base and repeat the process as many times as desired. It seems the fastest way to gather big amounts of wood in the least amount of time.
Collectibles[edit | edit source]
Castoroides will gather wood autonomously while on wander or if set to do nothing while a tree is in its immediate vicinity.
|Castoroides will automatically cut trees when near them.|

Notes/Trivia[edit | edit source]
For information pertaining specifically to the real-world Castoroides, see the relevant Wikipedia article
- First revealed by Jat on 06/20/2015 
- Before the introduction of the Direbear and the Redwood Forests with Megaloceros in it, hunting Castoroides is the easiest way to gather Pelt outside the tundra. Keep in mind that they are rather rare, however, and may be worth more alive than dead.
- In life, Casteroides' incisors were much broader and thicker than modern beavers, so they would have been less effective at cutting wood. For this reason, many paleontologists believe they did not construct dams.
- Can be picked up by an Argentavis and Quetzal.
- Despite having the oxygen attribute, it never drains when the beaver is underwater. Thus beavers are incapable of drowning.
- When riding a Castoroides in first person view, the camera is placed slightly behind where it should be, as you can clearly see its saddle.
- A map of giant beaver dam spawn locations can be seen in the article Giant Beaver Dam. These are also good locations to find beavers, as they spawn in pairs around the dens.
