ON THE FOOD OF NUDIBRANCHS

IBRAHIM AHMED ABOUL-ELA 1

1 Faculty of Science, University of Cairo, Giza, Egypt

1. Nudibranchs exercise considerable choice in the selection of their food. There is a complete chain of conditions from animals feeding exclusively on animal diet to animals depending more or less completely on algae for their food supply.

2. Deprived of all other kinds of food, nudibranchs can depend to a certain extent on suitable planktonic organisms for their diet.

3. Death of the animals does not follow reproduction and spawning, but results when the animals lack a suitable supply of food materials.

4. Large colonies of certain species may disappear as a result of migration after spawning to places where more favourable conditions of food, etc., prevail for the adults.
