Spotted foot nudibranch
Tayuva lilacina
Family Discodorididae
updated Oct 2016
Where seen? This large nudibranch is well camouflaged and thus often overlooked. Even when discovered, it's quite boring so most people don't get excited about it. On coral rubble and encrusted rocks and under stones. Commonly seen on our Northern shores. It appears to be seasonally common. It was previously known as Discodoris lilacina.

Features: 8-10cm long. Broad, somewhat stiff body that looks like coral rubble. Body pattern camouflages it well against sand and rubble, usually grey or brown, sometimes pinkish. Faint dark ovals about 3-4 in three rows along the body surface. The pale underside has dark blotches and spots. Large rhinophores and frilly gills.


There are several similar looking nudibranchs. One of them is Discodoris fragilis which is said to easily break off (autotomise) its mantle skirt when handled. The ones we have handled don't do this, but they do produce a LOT of slime which is really hard to wipe off afterwards.

Dr Bill Rudman considers the older name Discodoris lilacina more suitable for all the animals that might be called Discodoris fragilis.
