What is a sea cucumber?
Quick Answer
A sea cucumber is a marine animal related to starfish and sea urchins. It feeds on organic material in sediment and helps recycle nutrients on the seafloor.
The Full Story
Sea cucumbers are echinoderms, not plants, and they play a major role in ocean ecosystems. They often feed by swallowing sediment and extracting organic matter, which helps clean and mix the seafloor. Some species can defend themselves by ejecting sticky internal organs or defensive threads. Their body shape is soft and elongated, but they are closely related to the more familiar starfish and sea urchins.
