Size: 0.75 inches to 6.5 feet. They then observe invertebrates in an outdoor, or aquarium setting to look for evidence of how the organism uses its body parts to survive. This requires the sea cucumbers to rapidly process large amounts of water that is taken in and expels through the anus. When threatened, they are able to release all internal organs into their surroundings.

For each characteristic of the hadalpelagic zone that students listed on the Deep-Sea Creature Project Planner worksheet, have them brainstorm possible adaptations that would allow an animal to survive and thrive in a place with that characteristic.

Like most sea cucumbers, this species has several unique adaptations: A unique structure called a respiratory tree is located near its anus. Also, when sea cucumber is disturbed, they can expose skeletal, hook-like structures that would make them harder for predators to eat. They also have various forms of connective tissues that comprise them.

The cucumber will re-grow these tubules in the period of a few weeks. When that fails, they can actually turn themselves inside out, spraying digestive acids at the invader.
