To move forward, the cucumber pushes water into the feet through a water vascular system, which makes the feet firm and allows them to act like tiny legs that creep the cucumber along. Each produce seashells that are coiled in the adult stage. Their most notable characteristic is the pair of stalked rhinophores or horns at the head of the Slug. Some sea slugs also have exposed gills on their backs (in fact, the term “nudibranch” comes from Greek and Latin words meaning “naked gills”), which can appear feathery and brightly-colored. As with most sea slugs and their relatives, Ragged Sea Hares are cross-fertilizing hermaphrodites (male and female reproductive systems in same individual), with one reproductive encounter resulting in two fertilized individuals. This summer, I have been volunteering at the new Marine Life Center at the The anatomy, behavior, feeding, and reproductive adaptations of gastropods vary significantly from one group to another.
