A marine worm belonging to the family Nereididae that exhibits heteronereis, a form showing different body structures than the typical form.
From Greek hetero- (different) and Nereid (from Nereus, the sea god), combined with -id (member of a group), referring to polychaete worms with variable morphological forms.
These sea worms are shape-shifters of the ocean floor—they can switch between a crawling form and a swimming form, completely changing their body structure depending on whether they need to hunt or escape!
