Sea Slugs inc Nudibranch; Opisthobranchia

Not all the Sea Slugs (Opisthobranchs) are actually true Nudibranchs. We also have 2 vegetarian sub-orders; the Sap-Suckers and the Sea Hares, as well as the carnivorous Headshield Slugs.

Sea Hares; Anaspidea

Algae eating sea slugs with rolled rhinophores and a water circulation system similar to that of a bivalve. Named after their rabbit-shaped appearance, they are also herbivorous. (3 Galleries)

Headshield Slugs; Cephalaspidea

These opisthobranchs spend more time under the sand than above, so are not often seen unless you're out looking for them. (7 Galleries)

True Nudibranch; Nudibranchia

The name means literally naked gills although not every true nudibranch actually has external gills. We have got Aeolids, Arminians, a Dendronitid and lots of Dorids. (3 Albums, 1 Gallery)

Sap Suckers; Sacoglossa

Vegetarian Opisthobranchs with distinctively rolled rhinophores. (7 Galleries)
