UMBRELLA SLUG

Quite rare in a wide range of habitats, from exposed tidepools, algal meadows, or rubble where it feeds upon sponges.  Two forms are currently lumped into this circumtropical species in need of further study; a brown form with small and medium-sized compound tubercles, and orange form with large simple tubercles.  Attains at least 6 inches.  Formerly known in Hawaii as Umbraculum sinicum.
