Description
Favorinus (J. E. Gray, 1850) is an accepted genus of small aeolid nudibranchs in the family Facelinidae, known for feeding on the eggs of other sea slugs, including sea hares and nudibranchs (Hexabranchus eggs have also been recorded). Species are known from the Atlantic and Mediterranean (F. branchialis, F. blianus) and from the Indo-Pacific, including the Red Sea (F. mirabilis). F. branchialis grows to about 2.5 cm, and each ceras ends in a cnidosac (stinging-cell sac).
