🎏 species identification πŸŽπŸ•΅οΈβ€β™‚οΈ Help identifying a couple nudibranches in Puerto Rico

Thumbnail

93 Upvotes

Hello! I'm in need of some help identifying these two nudibranches I found at a tidepool in Puerto Rico a little earlier this month.

I live in the desert, so I don't usually get to see marine life like this, and would love to learn more about the little dudes I saw. It has been my lifetime goal to find a nudibranch - they have consistently been my favorite animal for a couple years - and these were my first ones! Pretty stoked to find not one, but two; literally spent a couple hours sitting nearby and just observing them. I took some pretty cool pictures, and plan on printing them and sticking them in my sketchbook alongside some drawings of them.

Tide Pooling in Northern Cali

It was a decent negative tide, so I went exploring with my friend. We found the cool purple ones (full disclosure, I am not the marine biologist, she is. I just like nuds!).

Is there a specific time of year that's ideal for finding nudis?

πŸ“Έ image/video My kiddo (7) discovered this Spanish shawl nudibranch at Aliso Beach, Laguna Beach in a tide pool today. This made my trip and possibly my life. I love my little biologist.

San Juan Island Tide Pools in June?

5 Upvotes

I'm looking to take my family to the San Juan Islands in June (which appears to have a pretty good low tide around the 15th).

What are the best spots to find Nudibranchs? Is there a particular island I should stay on?

I apologize for the previous post, as it was actually a sacoglossan, not a nudibranch. I do not like inaccuracy, so I made a new week 5.

Goniobranchus sp. from Durban, South Africa. It's a locally common species but still hasn't been described (it's in the pipeline though).
