3. Are sea cucumbers vegetables?

**Are sea cucumbers vegetables?**  Sea cucumbers are **animals**, not vegetables. Chocolate chip sea cucumber*Chocolate chip sea cucumber found at Johnston Atoll. Most sea cucumbers are scavengers, moving along the seafloor and feeding on tiny particles of algae or microscopic marine animals collected with tube feet that surround their mouths.* Found only in salt water, more than a thousand species of  sea cucumbers exist around the world. These squishy invertebrates are  echinoderms, making them distant relatives to starfish and urchins. Unlike starfish or sea urchins, the bodies of sea cucumbers are covered with soft, leathery skin instead of hard spines. If you ever encounter a sea cuke and it feels threatened,  you could be in for a surprise. Some sea cucumbers shoot sticky threads at  their enemies, entangling and confusing predators. Others can violently  contract their muscles and shoot some of their internal organs out of their rear ends. The missing body parts are quickly regenerated. Most sea cucumbers are scavengers, moving along the seafloor  and feeding on tiny particles of algae or microscopic marine animals collected with  tube feet that surround their mouths. The particles they grind down to smaller  pieces are further broken down by bacteria and become part of the ocean's nutrient cycle. This is a similar role to that which earthworms perform on land. Sea cucumbers are enjoyed as meals for other critters such  as fish and crabs. In some places, especially Asia, sea cucumbers are  considered a delicacy and are enjoyed by humans. Sea cukes are certainly a little odd, and definitely not something you'd ever find in your garden.
