Mystery critters on sponge at Aw Shucks

So there's the first mystery critter that was sitting on a sponge at Aw Shucks in Lembeh

It looks like a pink shrimp to me, but I got no further than that.

The second mystery critter sat on the same sponge and according to Jandri was a sort of opisthobranch

The shrimp is Gelastocaris paronae. The second one is a poser. From the picture alone my first guess is a highly camoflagued crab but I suspect your dive guide probably had a better view than me. obviously you'll just have to go back & try again!

Thanks worm girl!

Much appreciated!
