B. coerulescens are quite small, typically between 4 and 7cm. You can identify them by all the weird blue and yellow fringes that grow out from their bodies. These growths are called Cerata, and they aide in respiration and defense. This species consumes Anemones (as do most members of their family). Anemone venom passes through the Nudibranch and actually collects at the tip of the Cerata, making the Nudibranch venomous as well!
Berghia coerulescens is a common species in the temperate waters of its range. They are also sometimes kept in captivity, though they have a relatively short life expectancy (only a few months).
