This family of polychaete worms contains about 500 mostly marine species. They can be found in all water depths – hiding under rocks, burrowing through mud, and foraging in seaweeds. They are generally omnivores but some species are actively carnivorous. When reproducing, ragworms morph into a new form known as an “epitoke” during which their digestive system may degenerate and all energy is diverted to reproduction – it dies after reproduction. This “epitoke” stage was once thought to be a different species.
