Distribution

The distribution of Phyllodesmium longicirrum includes Australia and Indonesia.[1]

Description

The length of the slug is 33–140 mm.[1]

This species contains photosynthetic zooxanthellae.,[1] which allow it to draw energy from sunlight. Hence its common name, the Solar-Powered Phyllodesmium.[2]
