I am not sure on the ID for these first nudibranchs – or if they’re even the same species – but I am pretty sure they are in the Aeolid family. They were all tiny little things… each less than half an inch long.
This second set, are in the Adalaria family. We had spotted dozens of them during a dive at Scenic Beach State Park while my macro lens was broken and so we made a return visit to get some better photos.
