Atagema spongiosa is very well camouflaged. In the field it is almost invisible, though is grows up to 20 cm. I discovered my first one by chance in a tidepool, frankly said: I stepped on it when walking to the divesite, and noticed there was some soft under my foot. This species is in almost all publications on sea slugs (published before 2000) as Trippa spongiosa. Concerning the change of Trippa to Atagema have a look at Valdés & Gosliner (2001).
