These nudis are very common on the docks where I moor my boat. This picture has the saturation punched up, but still fails to convey just how trippy they, and most other nudibranchs, look in person. The iridescence in the rhinophores and cerata is something that can be tricky to capture with imaging. Here is a different angle of the same species.
thx for sharing! we did some underwater photography shenanigans back in the 00's and wow, shooting pics underwater is so very different from shooting them above.. Wow.. Nature = amazing
