Dorididae


Sea lemon is a loosely applied common name for a group of medium-sized to large shell-less colorful sea slugs or nudibranchs, specifically dorid nudibranchs in the taxonomic family Dorididae and other closely related families. These are marine gastropod mollusks.
The Monterey sea lemon is Doris montereyensis and the mottled pale sea lemon is Diaulula lentiginosa.
The common name sea lemon probably comes from these animal's visual similarity to a lemon based on such qualities as the roughened skin, the oval form when seen from above, and the common but not inevitable orange to pale yellow coloration.

Description

These dorid nudibranchs can be large, rather flattened, and oval in shape when seen from above. They have two hornlike projections on the head, and a rosette-like tuft of gills on the back of the animal. The mantle is sometimes sprinkled with black dots, and it is covered in small bumps, which are called tubercles.

Life habits

Sea lemons feed on sponges. They lay ribbons of white or yellow eggs.
Taxonomically the Dorididae is a family of several genera, the dorids named after the mythological ancient Greek sea nymph Doris.
