Aplysia vaccaria, also known as the black sea hare and California black sea hare, is a species of extremely large sea slug, a marine, opisthobranch, gastropod mollusk in the family Aplysiidae. [1] It is the largest sea slug species.
The maximum length recorded for the California sea hare is 75 cm (30 in) when crawling, thus fully extended, although most adult specimens are half this size or smaller. Adult animals can weigh up to 7 kg (15 lb). [4] [5] A closely related species, Aplysia vaccaria, the black sea hare, can grow larger still.

MONTEREY, Calif.

The Monterey Bay Aquarium Research Institute posted video online of the new sea slug floating gently in the depths.
In addition to trapping prey, the slug's hood can snap shut and propel the animal away from danger. Predators might overlook the sea slug's transparent body or be startled by its bioluminescence ...
Aplysia (/ ə ˈ p l ɪ ʒ (i) ə /) is a genus of medium-sized to extremely large sea slugs, specifically sea hares, which are a kind of marine gastropod mollusk. These benthic herbivorous creatures can become rather large compared with most other mollusks.
The order Aplysiida, commonly known as sea hares (Aplysia species and related genera), are medium-sized to very large opisthobranch gastropod molluscs with a soft internal shell made of protein. These are marine gastropod molluscs in the superfamilies Aplysioidea and Akeroidea .
