When it comes to my Aliens Collection, the weirder the better - and few fish are weirder than the larval-stage #Lamprogrammus #cuskeel

Spent 30+ minutes with this giant #mimicoctopus - of the dozens (hundreds?) I’ve encountered, this might be the biggest, with a legspan of >2’!

A giant #Pteropod #seabutterfly, Corolla spectabilis, cruising through the nighttime open ocean.

Shot in the wild, using scuba, while drifting out over the deep abyss, at night, off Okinawa.

I presume this is a type of Myctophidae lanternfish, but I’m not 100% sure.
TL ~2.5cm
Shot offshore from Palm Beach, FL in Feb2025

Straight outta Arrakis
Like the worm riders in Dune, an imperator shrimp rides atop of this 3” nudibranch. They’ve stayed together in the same spot for 4 weeks now!

While I don’t think anyone has made a specific designation between “larval” and “adult”, in the moorish idol, I’m going to label this one “post-larval”

Ctenophores, more commonly called comb jellies, are pretty much everywhere in all oceans, but they’re incredibly hard to see during the day. But at night...

Crazy-looking larval cusk eel with an impressive external gut. We’re still not sure why having the intestines on the outside is advantageous, but there must be a good reason 🤔

This larval-stage jack fish (aka trevally) is living inside the #jellyfish for protection against whatever might come his way.

One of the smallest Armored Sea Robins that I’ve ever seen - its body a little larger than a pea.
This is the same species featured in my Aliens Collection Print, “Alien #27”.

A beautifully-crowned #Tonguefish larvae (#Cynoglossidae sp.), drifting with the #plankton in #Okinawa. Don’t worry - it gets more “tongue-y” as it gets to its adult stage.

First (and only) time seeing this species - and this doesn’t appear to be a larval-stage - perhaps a juvenile, just post-metamorphosis.

I’ve watched this pair of #clownfish through two full breeding cycles over the past month and a half - as of yesterday morning, they’re empty nesters once again. It’s been cool documenting the whole process and watching the eggs develop.

The weedy #rhinopias (Rhinopias frondosa) is a holy grail species for any fish nerd, and I returned to shoot this guy several days in a row.
