Pleurobranchus areolatus
Notospidea are also referred to as side gilled sea slugs. They have an elongate plumed gill on the right hand side of their bodies. You can see these gills in the photo on the left above. Infact, you can see that the rhinophore are on the right of the photo and gills are on the bottom. This means that the gills are on the right side... just like a Notospidea should have. Members of the order are voracious predators. They have strong jaws and wide radula to enable them to scrape and feed on their prey. Most species feed on sponges, but some feed on hard corals or ascidians.
Notospidea is a small sized order with relatively high variation. Their shells can be external and limpet like, small and internal, or not existent at all.
