Trapania brunnea

A small brown nudibranch, this species is speckled with tiny white spots, and an irregular and intermittent white dorsal line. It is usually found in association with several species of sponge, where it eats the kamptozoans (small animals that superficially resemble hydroids) growing on their surface. It is very similar to Trapania benni, which differs by also having yellow spots on its body.
