Why the Lists and How we do it

First thing we do after ascending is set our cameras and put our glasses over our mask. We travel very slowly and search every inch of substrate. When we find a nudibranch species we take a photo of it, that way it is recorded. If we find one that is NEW we photograph it and collect it to look at more closely and study it's behaviors, plus see if it lays eggs. If this animal is new to science we preserve it for the Museum.

The List is a recording of nudibranchs we see on every outing. It shows what the common species are and how often we find the not so common ones. Plus it is an incentive to break the record.

Cheers...see you at the bottom!
