seen? This chubby delicately patterned sea hare is seasonally
common on our Northern shores, among seagrasses. Sometimes large numbers
are seen, at other times, not at all. It is also known as Paraplysia
8-12cm. Body large, heavy and smooth. With two pairs of tentacles:
one pair of oral tentacles forming flap at the front of the body.
When compared with sea hares of the genus Aplysia, sea hares
of the genus Syphonota have relatively small rhinophores which
are close together and situated further back from the head almost
between the long 'wings' or parapodia. When submerged, these wings
are held high. It is said that they can swim with their parapodia.
olive or yellowish greenish with tiny white spots forming patterns
Often found half buried in the sand, but sometimes crawling in the
open, especially near sunrise or at night. It lays long tangles of
pink egg strings among seaweeds and seagrasses.
What does it eat? It is believed
to feed on brown seaweeds, but in our observations, these animals
seem more abundant during blooms of the green sea
lettuce seaweed (Ulva sp.).
