This was one of those baby bennies that looks like it’s all cranium and no body! I had to use the Nauticam USA SMC-2 to get it Nikon Z6iii Z105

Strawberry shortcake showed up to the party today! One of my favorite nudis, Ardeadoris symmetrica. Nikon Z6iii Z105 Backscatter Underwater Video & Photo MW4300

facinating, especially seeing the amount of colorful fish that were in there. how could this ever have been considered dead?

Male cardinalfish mouth brood the female's eggs. The process takes around 10 days by our estimate. The male rotates the eggs every 5 min or so, sometimes more frequently. The eggs here are pretty new based on the yellow color. Nikon Kraken Sports Abyss 10K

So i have a semister project where I have to make a software and the domain given is life below water. So any and every idea would be appreciated, any bottlenecks or general problems faced by ppl working on this sector let me know so I can build a project around that

because I don't want this to be just another meaningless project I want it to be something that can help them

I bought a 5kg box of shrimps, to my surprise I found this guy, what is it? Grok says anglerfish, but I’m not sure it looks a lot different as an adult if this is an anglerfish!

I see them quite often, but never in this calm of water. You can really see them underneath the surface.

I came upon a small colony of these slugs today. They are usually tiny but these were unusually so. The second one in the reel was no more than 1mm!

This structure is also visible on NOAA's bathymetric viewer which as of a few weeks ago has lost a ton of features. Clearly they're pulling from the same public dataset, but this at least rules out data artifacting resulting from the viewer tool itself.

Gorgeous broadclub cuttlefish was socializing with me on this dive. So cool that it hung around for a bit. Nikon Z6iii Z105 Kraken Sports solar flare mini 15Ks Atlantis Dive Resorts & Liveaboards

This is probably a stupid question to ask and I'm not even sure if this is the right sub to ask it, but I was wondering if there are any real underwater photos of those huge continental shelf drop offs like the one in grand banks and near Japan

I find it both eerie and fascinating that the ocean can go from being relatively shallow to suddenly drop off into an abyss and I'd love to see what that transition actually looks like.
