What defense does a sea cucumber have?

* Evisceration: Sea cucumbers can eject their internal organs through their anus as a defense mechanism. This can confuse predators and give the sea cucumber time to escape.

* Cuvierian tubules: Some species of sea cucumbers have Cuvierian tubules, which are sticky threads that can be shot out of the anus as a defense mechanism. These threads can entangle predators and make it difficult for them to move.

* Autotomy: Some sea cucumbers can autotomize, or detach, a part of their body as a defense mechanism. This can distract predators and give the sea cucumber time to escape.

* Camouflage: Many sea cucumbers have camouflage to help them blend in with their surroundings and avoid predators.

* Chemical deterrents: Some sea cucumbers produce chemical deterrents that can make them unpalatable to predators.
