Doridina have a wide range of species, and by far the most photographed of all the sub orders.
This sub order tends to follow the same format in each species too, whereas there are some bizarre looking species in the other sub orders that I found difficult to relate as nudibranchs.
Most easily identified follow the template of the Chromodorididae family
Let us briefly look at some of the physiology taking this Chromodoris lochi as an example:
Main Doridina Families;
Main Dendronotina Families;
Main Arminina Families;
Main Aolidina Families
