holothurin
Quick Summary
Holothurin is a toxin produced by some species of sea cucumbers, which are marine invertebrates belonging to the class Holothuroidea. While these toxins can be lethal to small aquatic animals, they are not harmful to humans. Sea islanders have historically used sea cucumber juices to stun or kill fish. Sea cucumbers themselves have soft, cylindrical bodies and are found in all oceans, often on coral reefs. They are harvested for various products, with the dried body wall, known as bêche-de-mer, being a delicacy in Asia. Overfishing has significantly reduced the populations of many valuable sea cucumber species.1
