The Top Ten

1 Glaucus Atlanticus Glaucus Atlanticus Glaucus atlanticus is a species of small, blue sea slug, a pelagic aeolid nudibranch, a shell-less gastropod mollusk in the family Glaucidae.

Also known as the blue dragon, blue glaucus, sea swallow, blue angel, blue sea slug, and blue ocean slug (gee that's a lot of names X-D). Despite looking beautiful, this sea slug's sting is similar to a Portuguese man o' war's, since it feeds on them - BlueFrostOfThunderClan

2 Cyerce Nigricans

Most species of Cyerce are cryptically colored, except this one. It's black with yellow or orange markings and white spots. It has autotomy ability; it can cast its cerata to confuse predators - BlueFrostOfThunderClan

3 Hypselodoris Purpureomaculosa

It's white with orange fringed mantle. There are purple spots that can vary from red to black on it's upper mantle - BlueFrostOfThunderClan

4 Nembrotha Kubaryana

It's a large dark-colored sea slug with green stripes running down the body or green raised spots. The margin of the foot and head is vivid red-orange. It defends itself by shooting slimy toxic mucus to the predator. Not to be confused with the Nembrotha cristata, which has no red-orange - BlueFrostOfThunderClan

5 Lettuce Sea Slug

Makes me kinda HUNGRY

6 Chromodoris Britoi

It's blue and purple with some yellow marking and yellow edges. Its rhinophores and gills are purple - BlueFrostOfThunderClan

7 Spanish Dancer

It's a large orange-red nudibranch. This nudibranch can swim with its edges to escape predator (and the way it swims is magneficent) - BlueFrostOfThunderClan

8 Twin-Crowned Nudibranch

It's white or grey and usually there are black, yellow or orange stripes longitudinally along the notum. Its head has 6 yellow projections (making it look like wearing a crown). Along its gills, there are 2 or 3 pairs of yellow projections. Not to be confused with the crowned nudibranch and the fourline nudibranch, which don't have the "crown" along the gills - BlueFrostOfThunderClan

9 Moridilla Brockii

This white sea slug has bright red tips to the cereta and rhinophores. Those red tips to the cereta are actually a warning, because it stings - BlueFrostOfThunderClan

10 California Blue Dorid

It's body and mantle is dark blue with yellow spots - BlueFrostOfThunderClan
