Cadlina pellucida

Cadlina pellucida is a species of sea slug that belongs to the family Cadlinidae. This marine gastropod mollusk is characterized by its soft body, which can be difficult to distinguish from similar species. It typically inhabits the Mediterranean Sea, where it is found in demersal environments. This nudibranch is a simultaneous hermaphrodite, meaning that individuals possess both male and female reproductive organs. During mating, both individuals engage in a behavior where they dart their penises toward one another, leading to one acting as the male and the other as the female. After mating, eggs are deposited on a substrate, where they develop into a planktonic larval stage before maturing into adults. Encounters with Cadlina pellucida during dives can be intriguing, as divers observe these creatures in their natural habitat. They are generally harmless to humans and do not pose any threats. The conservation status of this species has not been evaluated, which means that there is limited information regarding its population trends and threats.
