The
Sea Lemon is a large (up to 20 cm) flattened oval marine
nudibranch without a shell. They have two hornlike projections at one end and a tuft of gills at the back. The mantle is usually sprinkled with black dots.
They feed on
sponges and other
sessile animals or even on dead organic matter. The Sea Lemon lays ribbons of yellow eggs. Its upper surface is covered in 'bumps', which are called tubercles.
The roughened skin, the oval form, as seen from above, and the orange to pale yellow color suggest the
fruit for which the animal is named (
lemon). It has also a sharp lemon scent, which seems to discourage predators.
Taxonomically it is a family of several genera, the
Dorids named after the Greek sea goddess
Doris. (See
