Some species of coral reef sea cucumbers defend themselves by expelling sticky cuvierian tubules to entangle potential predators. How does a sea star eat? Spiny Lobster - this one is usually found in warm waters and is also known as a rock lobster. We hypothesized that juvenile lobsters may be at particular risk if attracted to casitas . Spiny lobster sounds 237 The sound-producing mechanism itself may relate to its anti-predator function. Despite their phylogenetic closeness, both species have many different life-history traits that may partially explain their coexistence. Staaterman, T. Claverie & S.N. They use their spiny exoskeleton to protect themselves from these animals, and some species have poisonous spines to stun their predators.
