In Australia sea hares are sometimes known as "beach blobbies".

This is a circumtropical sea hare, the only species in its genus.

The black sea hare can grow to be very large.

Many reef keeping clubs have started programs where groups of hobbyists "share" a single sea hare among a large group.

The color of this sea hare is very often brown with paler spots, but it can be various other shades including plain black all over.

This sea hare lives in areas that are sheltered from rough currents.

This sea hare occurs in the eastern Atlantic and the Mediterranean.

After the breeding period, there occurs a mass mortality of the animals, just like the sea hares.

The general description of sea hares can be found in the article on the superfamily Aplysioidea.

The colour of the spotted sea hare is very variable, from pale gray to green, to dark brown.
