More on Sea Cucumber
Sea cucumbers are echinoderms, related to sea stars and sea urchins. They play a vital role in benthic ecosystems by breaking down detritus and oxygenating the seabed. Found in a variety of environments, they are often seen slowly crawling along the ocean floor. Some species eject sticky filaments or even internal organs as a defense mechanism. While harmless to divers, sea cucumbers are considered a delicacy in some cultures and are vulnerable to overharvesting.
