Revision 1

The Coral Crab is a large crustacean in Subnautica 2, associated with the Coral Gardens region. It is notable for being able to damage the hull of a player's vehicle, which makes it a real hazard when driving through its territory. Its size has led some early reference lists to label it as leviathan-class, but that classification is disputed, so it is presented here as a large crustacean.

Overview

The Coral Crab is one of the larger creatures the player encounters that sits outside the clearly confirmed leviathan set. Whether it qualifies as a true leviathan-class organism is disputed: some launch-era lists place it in that tier, while others treat it as a large crustacean below the threshold. Until the in-game classification is settled, this page treats it as a large crustacean and notes the disputed label rather than asserting a leviathan classification.

Behavior

The Coral Crab appears to be tied to the Coral Gardens, where its bulk and armored shell make it a standout among the local fauna. Its most documented interaction is with vehicles rather than with a swimming player: it can strike and damage a vehicle's hull. The full range of its behavior, including exact triggers and movement patterns, is not thoroughly documented in the current Early Access build, so finer details should be treated as unconfirmed.

Threat to Vehicles

The Coral Crab's defining danger is its ability to damage vehicle hulls. A player relying on a submersible to cross the Coral Gardens can take meaningful hull damage from one of these crustaceans, which is more punishing than the chip damage many smaller creatures deal. Because the game follows a no-weapons philosophy, there is no way to kill it; the response is to avoid it or break away before the hull is compromised.

Evasion

• Watch your hull integrity when driving through the Coral Gardens and disengage if a Coral Crab starts striking the vehicle.

• Steer around the crustacean rather than through it; its threat is concentrated when you are in contact range.

• Keep an escape route in mind so you can pull the vehicle clear before hull damage stacks up.

• On foot you can use the surrounding coral terrain for cover to slip past it.
