Ceratosoma amoena - information needed

September 27, 2001
From: Edward Terry

Would anybody know the Common Name and food habits for the nudibranch called Ceratosoma amoena ? (Sub-order Doridacea). It is for a school project and I would greatly appreciate any response.
Thanks!

Dear Edward,
Your photo looks like a New Zealand animal. Are you from New Zealand? If you look at the photos at the top of the Ceratosoma amoena page (above your message) you will see that it is found in northern New Zealand and much of temperate Australia. You will also find more information in the other messages below yours.

Now to your actual questions. It does not have a common name. Of the millions of animal species worldwide, only a very few have common names - you have to have fur, or feathers or be something we eat, or be useful or a pest before we bother to give things a common name. That leaves out most of the worms, insects, snails etc which make up the the world's biodiversity. But why bother with a common name - just use the scientific name. It is used all over the world, so you will never be misunderstood, and it's not very difficult to pronounce. Gardeners use scientific names all the time -Hydrangea, Geranium, Banksia, Hebe etc with no problem at all.

Now what does it eat? I'm afraid all I can say is that like all the other members of its family Chromodorididae it will be a very fussy eater, probably eating only one or a few species of sponge. Unfortunately at present we don't know which species it eats.

Good Luck with your project,
Best wishes,
Bill Rudman
