Genus

Common name: Side-gill slug

Scientific name: Pleurobranchus

Pleurobranchus is a genus of sea slugs, specifically side-gill slugs within the family Pleurobranchidae. These marine gastropod mollusks are known for their unique respiratory structure located on the right side of their body, which gives them their common name. They are nocturnal creatures, often found on reef slopes and under rocks during the day. Pleurobranchus species are not common in the aquarium trade, but they can be fascinating to observe due to their behavior and feeding habits on sponges and other sessile invertebrates.
