There are two main types of nudibranchs- dorid and eolid nudibranchs. Dorid nudibranchs breathe using gills that are located at the back end of their body. Eolid nudibranchs have finger-like appendages called cerata that cover their whole back. These cerata can be a wide variety of shapes, and are used for digestion, defense and breathing. These animals have very poor vision, only being able to see ‘light’ and ‘dark’. They also have a short life span, with some only living for a few weeks!
