Hermit crab. Hermit crabs wear shells to protect their soft abdomens, which are asymmetrical and curved to fit the spiral shape of their shell. Like all crabs, hermit crabs are decapods; they have five pairs of legs, including a pair of claws. One claw is much larger than the other, the hermit crab uses it for defense and food shredding while it uses the smaller claw for eating. The second and third pairs of legs help the crab walk, and the last two pairs hold the hermit crab in its shell.

California sea cucumber. Sea cucumbers are related to sea stars and sea urchins. The sharp looking spines are soft to the touch and disappear into the skin when disturbed. If this visual defense doesnt work, the sea cucumber will expel its respiratory system. When this occurs in the wild it can regrow the lost organs.

Electric eel. Like other members of the South American knifefish family, the electric eel relies on electrolocation to navigate in find food in murky water. However, its electric organs are more powerful than its relatives, allowing it to produce sufficiently high voltage pulses to stun predators and prey.
