It's finally wildcard day for #SlugsVsFish #SlugsVsFishes!

One of the most amazing things about sea slugs is the diversity of morphology! Here's a thread of some the amazing shapes of nudibranchs our scientists have found in the field.

First up check out these colors! 😍

This gorgeous green nudibranchs was photographed by Chela Zabin in the Phillipines. #SeaSlugSquad

But what if you prefer stripes to one standard color? 🤔

Or spots? Nudibranchs have it all!

Now let's look at how different their body shapes can be!

Nudibranchs' cerrata can be in many different shapes, branched or curly, and different colors, some with shooting venomous nematocysts.

Or maybe intense cerrata aren't your favorite... Perhaps a more simple shape and color is to your style?

Some sea slugs still even have a pronounced shell!

Don't forget size! Even though these two are the same colors, the one on the left (on a bryozoan colony) is many times smaller than the one on the right (in a sandwich Tupperware).

Basically what we're saying is that you never know what to expect when you find a sea slug. And that is part of the joy of finding them!

This species is Bulla gouldiana from Palos Verdes, CA. It is a type of bubble snail.

This nudibranch is Doris cf. kerguelensis, and was photographed in Antarctica!

Photographed on a dive in Monterey, CA, we think this one is cf. Dendronotus iris.

This bright blue nudibranch is Doris pecten from Maui, HI!

This is Antiopella fusca, formerly called Janolus fuscus.
