Distribution
editThis species was first described from Miami, Florida.[1] It has also been reported from the Bahamas.[3]
Description
editThis goniodorid nudibranch is cream with brown patches, with white bosses on the body.[1] This appearance with raised tubercles is illustrated in one photograph from Florida.[4] Larger animals have extensive brown patches reminiscent of Trapania brunnea and small raised tubercles. These are thought to be the adult form of this species.[5]
The maximum recorded body length is 12 mm.[6]
Ecology
editMinimum recorded depth is 0 m.[6] Maximum recorded depth is 0 m.[6]
Trapania dalva probably feeds on Entoprocta which often grow on sponges, sea squirts and other living substrata.
