Creature of the Month: Dendronotus Nudibranch

Dendronotus lacteus

From the 1930s until 1998 these two nudibranchs were thought to be the same species: Dendronotus frondosus.

Dendronotus frondosus

However, genetic analysis by M. Tholleson suggested that the two colour forms were distinct species and so he resurrected an old name Dendronotus lacteus for the white one.

Not difficult to tell apart you might think, but D. frondosus comes in many colours.

At first all the colour-forms were all thought to be independent species, then all the same species, and now some the same and some different.

In 2017 a third species of Dendronotus was identified, Dendronotus europaeus. Like D. frondosus and D. lacteus this nudibranch is common in shallow waters in northern seas.

Dendronotus frondosus means leafy black tree. The nudibranch feeds on hydroids and from them obtains nematocyst stinging cells which it uses for defence from predators.

The photos were taken in the Isle of Man by Tim Nicholson. The nudibranchs are found in the British Isles, on both the Atlantic and Pacific coasts of the United States and Canada, northwards into the Arctic and south as far as France.
