Duvaucelia odhneri, is a species of dendronotid nudibranch. It is a marine gastropod mollusc in the family Tritoniidae.

Contents

The specific name odhneri is in honour of Swedish malacologist Nils Hjalmar Odhner. This species was originally described as Duvaucelia odhneri but this became a homonym of Tritonia odhneri Marcus, 1959 when the genus Duvaucelia was moved within Tritonia in 1983. [2] In 2020 the genus Duvaucelia was brought back into use and the name reverted to the original combination of Tardy, 1963. [3]

Distribution

This species is found in the north Atlantic Ocean off the United Kingdom, Ireland and France. It is also reported from South Africa but DNA evidence suggests that this is a distinct, as yet un-named, species. [3] Around the South African coast this species is found on both sides of the Cape Peninsula. It is known from 10–30 m. [4]

Camouflage: the South African whip fan nudibranch and its egg ribbon

The South African whip fan nudibranch is a well-camouflaged animal which mimics the gorgonians on which it feeds. It is a small nudibranch, reaching 30 mm. Its branched rhinophores extend from cup-like sheaths. Paired branching projections down the length of the body resemble the feeding polyps of its prey species of sea fan. [5]

Ecology

The egg ribbon

The whip fan nudibranch feeds on gorgonians of the genus Eunicella . It lays a thin zigzag spiral of eggs around the main axis of these sea fans. The egg mass is also coloured to match the gorgonians.

Alcyonacea Order of octocorals that do not produce massive calcium carbonate skeletons

Alcyonacea, or soft corals, are an order of corals. In addition to the fleshy soft corals, the order Alcyonacea now contains all species previously known as "gorgonian corals", that produce a more or less hard skeleton, though quite different from "true" corals (Scleractinia). These can be found in suborders Holaxonia, Scleraxonia, and Stolonifera. They are sessile colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Common names for subsets of this order are sea fans and sea whips; others are similar to the sea pens of related order Pennatulacea. Individual tiny polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across, but only a few inches thick. They may be brightly coloured, often purple, red, or yellow. Photosynthetic gorgonians can be successfully kept in captive aquaria.
