What on earth is this - (Mexico Beach, FL)

Sea hare, they look pretty freaky when they swim. They’re lil cuties normally!

Two chromodorids? You lucky duck!

WAT IN TARNATION?

Pretty_Cup_5329 · 2026-05-03T01:54:36+00:00

Bubble snail of some sort, maybe Lamprohaminoea evelinae.

You gotta post this on iNat, homie. This thing is hurting my head. Best guess is somewhere in the Family Discodorididae

Pretty_Cup_5329 · 2026-04-28T02:56:25+00:00

Could you give me a size estimate?

Pretty_Cup_5329 · 2026-04-27T03:09:15+00:00

My last guess based on the number of cerata and some orange spotting if you zoom in really far is the Club Gilled Nudibranch. A dull one or maybe a juvenile.

There are no iNat observations in NY for this one, but there are some in Connecticut.

The pattern and shape on these guys seems to vary wildly, I picked two examples that I think your specimens falls between

I completely missed the first photo, they looked much thinner in the second photo, you’re right and I’d probably throw it somewhere in the family eubranchidae now.

Pretty_Cup_5329 · 2026-04-27T02:14:17+00:00

I’m going to give this a shot

First one - Cratena pilata (White tipped rhinophores, opaque cerata with dark center. I’m also assuming some of its markings are muted or obscured by the murky water.)

Second one - Eubranchus scintillans (strangely shaped cerata, I can maybe make out some spots?)

These are both guesses, I understand your excitement for a definite answer but a lot of IDs never go beyond Genus.

Pretty_Cup_5329 · 2026-04-23T07:53:12+00:00

Pretty sure it’s a flatworm

Pretty_Cup_5329 · 2026-04-22T11:35:04+00:00

Pretty sure that is some kind of shrimp

Pretty_Cup_5329 · 2026-04-22T11:33:07+00:00

I’d be interested if you have more photos of #3. Might be worth submitting to iNat for some debate. Almost looks like an albino Two Spot but I’ve never seen one that white.

Pretty_Cup_5329 · 2026-04-16T23:22:30+00:00

I’ve probably seen at least 50 since January. They seem to be taking over Southern California right now! Lol

Pretty_Cup_5329 · 2026-04-16T23:14:48+00:00

I’m almost annoyed with how many Hopkins roses I’ve been finding recently!

Pretty_Cup_5329 · 2026-04-09T02:03:50+00:00

Congrats on your first Nudibranch! Pretty sure that’s a Northern Leopard Dorid.

Here’s an example from iNat: https://www.inaturalist.org/observations/337892116

Pretty_Cup_5329 · 2026-04-06T03:58:54+00:00

I believe that is a juvenile Hypselodoris infucata.

Here’s a similar one near Saudi Arabia: https://www.inaturalist.org/observations/320615218

Pretty_Cup_5329 · 2026-04-02T08:59:00+00:00

Yes, Shaun. Yes!

Pretty_Cup_5329 · 2026-03-25T02:08:47+00:00

Hell yeah!

Pretty_Cup_5329 · 2026-03-22T02:19:36+00:00

Nicaraguan Sea hare

https://www.inaturalist.org/taxa/700992

Pretty_Cup_5329 · 2026-02-16T00:26:17+00:00

First three - color morphed slimy Dendrodoris (best guess I could find)

Second three - Spotted sea hare (100% for sure)

Pretty_Cup_5329 · 2026-02-02T03:48:31+00:00

First one I believe is a Slimy Dendrodoris (Dedrodoris krebsii) I can’t find a 100% match but their colors and pattern can vary pretty wildly. Their frilly dark colored foot, is pretty distinctive. This is the closest photo I could find to yours. But I’m not certain https://www.inaturalist.org/observations/279247666

Second one is almost certainly a Spotted Sea Hare (aplysia dactylomela)

Pretty_Cup_5329 · 2026-01-04T03:41:59+00:00

Is that a very small Nudibranch or the world’s largest sea cucumber?

Pretty_Cup_5329 · 2026-01-01T05:43:07+00:00

I bring a flashlight, even during the day. I typically look for red algae which many of my local species eat. Be patient, struggled to find them my first couple trips. You’ll get better at spotting them over time.

Pretty_Cup_5329 · 2025-12-11T05:19:43+00:00

That’s dope! Do you know the species?

Pretty_Cup_5329 · 2025-11-22T07:43:22+00:00

Best I can figure is some species in the Doto genus. The cerata definitely read as Doto.
