#phyllodesmium poindimiei

Phyllodesmium poindimiei is a brightly coloured aeolid nudibranch that can grow up to 5 cm long. It feeds on soft corals, and can be found throughout the Indo-Pacific. P. poindimiei near Hawaii eat a specific type of octocoral that is invasive to the area, so the slugs’ use for controlling invasive octocoral abundance has been studied - though the results were not promising.
