Many worms go through a planktonic larval stage, and in this case, the spaghetti worm is quite similar in form to its post-metamorphosis adult

The last 8 seconds shows an adult.

Larval footage: Okinawa. Adult: Florida

A very large juvenile diamond squid - this one measuring in at a whopping 3” - perhaps the 2nd largest I’ve ever seen!

Shot in the wild, using scuba, while out over the deep abyss, several miles offshore from Okinawa

#Lobsters go through an early life stage called #Phyllosoma where they’re planktonic, and they’re constantly on the lookout for a “life raft” - often something with stingy bits, like this muave stinger #jellyfish.

The #BlueButton, (Porpita porpita). It’s not a #jellyfish, but rather a colony of cooperating #hydroids.

Shot using #scuba, while drifting in the open ocean at night.

And yes, the lick test says it’s only mildly spicy.

Imagine wearing a #jellyfish as a helmet!?!
Well, that’s exactly what this juvenile jack is doing! Mostly immune to its sting, the jack has taken the jellyfish prisoner.

Shot using #scuba, out over the deep abyss, drifting at night.

The most beautiful #snail ever to exist!
Many #marine snails go through an early life stage called #veliger, wherein they drift along with the #plankton before settling onto the sea floor as an adult. We call this, #sparkles

Hey little bebeh Ornate Ghost Pipefish - what are you doing out here in the middle of the ocean in the middle of the night, drifting around with the plankton? Not something I’d expect to see out here!

I presume this is a type of Myctophidae lanternfish, but I’m not 100% sure.

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 🤔

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

Whalefish are often called tapetails when in their larval stage. This one’s tail was ~4x its 1.5” body length.
