Berghia coerulescens

Berghia coerulescens
I always love writing about Nudibranchs. They are such colorful little Gastropods! Today's Nudibranch is Berghia coerulescens, a species with that can be found in the Atlantic Ocean, as well as in the Mediterranean and Caribbean Seas. (I was unable to find any common name for the species, but if anyone knows of one, let me know!)

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).
