Tusoteuthis(Too-so-too-thihs) is rather powerful for its price, with fairly high damage and speed; however, its attacks are slow, it has no defense which is in understandable, and terrible health. It is the fastest marine animal in the game, tied by the Ichthyosaurus. Health and defense, however, are underwhelming and non-existent respectively, doubtless as a result of its soft skin. In the same way as Mayhem Egg dinosaurs, it changes its color by roaring (Pressing R or 1/AoE), though it's entire body changes instead of a certain portion as in the Mayhem dinos. This isn't very useful but works in some extremely rare examples (camouflage).
It was most infamous for its ability to carry out an exploit known typically as floor-glitch or any variation on that name. The "exploiters" performing it were commonly known as "ground exploiters" or "floor exploiters", based on how the player was able to get their creature under the floor of the map. By putting the squid head first against a vertical surface, switching the camera to face outside the map and then scrolling into first-person the Tusoteuthis may have appeared on the other side of the map. The player can then make a nest under the floor of the map, allowing them to bring in creatures such as a Megavore or a Mosasaurus. The player would then use these creatures to bite at creatures above on the floor of the map. It's been patched since. Whilst possible before the addition of this creature, this glitch was by far the easiest to carry out with a Tusoteuthis.
Its default color is a pale red, with long tentacles with black hooks on two of them. It has two fins on its head which it uses to swim along with large glowing pink eyes and a black beak between its tentacles. It looks a lot like a modern-day Humboldt squid. It can change it's color by roaring. Its model is a bit blocky. It still has quite an appealing design.
- It is the only aquatic creature in the game that cannot pick up other creatures (regardless of size)
