Photos
Ceratosoma brevicaudatum belongs to the more common branchs in Nelson Bay. I had never seen it before. It can vary in size dramatically. The species count relating to all common branchs might be understated, because I started to ignore them.

Elysia sp. could be a described species. But this is one of the genus where I am simply not up to date and not sure if the revision has already been published.
I list this branch as Mexichromis festiva. It belongs to the colour group with yellow marginal mantle bands and red dots.
The white fuzzy lines on the mantle of Doriopsilla miniata could be showing better. I simply chose this photo because I love the perfoliate rhinophores showing so clearly. I found this branch on an empty shell.
