NUDI GILL PIN-UP: Hopkin’s Rose Nudibranch

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 July’s supermodel:

Hopkin’s Rose Nudibranch

Bubble-gum pink papillae cover this beauty from head to toe. And now you are probably scratching your head and wondering, where’s the head and where’s the toe? Look closely for the two rhinophores poking out on the right end.

BINGO! That’s the head. A nudibranch’s toe (or foot) typically spans the length of its belly, but Rose’s mantle, head, and foot are kind of all merged together in one flattish base. Below is a cool shot of the edge of Rose’s foot/body/mantle. And in case you were wondering again which end you are looking at, well… those feathery bits are anal gills. So basically, she’s showing off her bodacious bum here.

Another unique thing about Rose is her extra-large middle tooth. Give us a smile, Rose!

Hubba Bubba!

You can find more of these cool creatures lurking in tidal pools all along the Pacific Coastline from Baja California to Oregon.

I hope you enjoyed meeting the Hopkin’s Rose Nudibranch. Stay tuned for August’s NUDI GILL Pin-Up!
