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

This large sea slug got its name because it's often green (but it can be other colors, like blue) and it has very frilly edge to its parapodia, which resembles a lettuce (but it kinda looks like a flower bed too in my opinion). - BlueFrostOfThunderClan

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
