61/100 Chromodoris lochi or blue sea slug. There is some variation in this type of sea slug, some sporting very fancy yellow or orange feathery bits. These feathery bits have rather lovely names; the front horn things are called rhinophores and the bum feathers are called the cerata. Nudibranch use their rhinophores to taste and feel things like water current, while the cerata are apparently used to help the sea slug breathe, though I understand some can also be used for attack. I guess it depends on the type of sea slug, which I’m rapidly discovering ARE like Pokemon and highly addictive.
