NUDI GILL PIN-UP: Nembrotha Aurea

In preparation for NUDI GILL, my debut picture book release in September 2022, I will be blogging about nudibranchs monthly. My hope is that you, too, will fall in love with these colorful little critters. Without further ado, allow me to introduce you to October’s supermodel:

Check out the spectacular colors on this elegant nudibranch! Getting any ideas for Halloween costumes here?

This little nudibranch feeds on colonial ascidians, otherwise known as sea squirts. Mmmmm, makes my mouth water!

All Nudibranchs are classified into sub-species. For example, this one falls into the Nudibranchia suborder of Dorid Nudibranchs. From there it breaks down further into the Phanerobranch category of Dorids. These nudibranchs are generally long and slender with well defined heads. They also have non-retractable gills on their backs. In fact, the word phanerobranch means “evident gill.” Just a little science stuff to geek out about.

Phanerobranch dorid nudibranchs sometimes exhibit a behavior known as rearing. Sometimes they do it because they are repulsed by something toxic or dangerous. Other times they lift their upper bodies up like this just to have a better “look” around. You never know, there might be a mate or something yummy to eat nearby. They sense such things through their rhinophores, not their eye spots.

Where’s the buffet?

These nudibranchs can be found in the Tropical Indo-West Pacific. Where’s that? It’s the Indian Ocean and beyond. A watery paradise stretching from the east coast of Africa all across the Asian coastline and touching the shores of Australia. This nudibranch really gets around!
