The current name for this is Corambe steinbergae, but it looks like our name providers don't know that yet. This was a really cool find for me. This is one of two very cryptic nudibranch that mimic the appearance of their food, the bryozoan Membranipora, which grows on kelp. This little guy was 8 mm tops, so I could hardly even tell it was a slug until I looked at the picture.
