Seen here catching a ride on a jellyfish because work smarter, not harder, this is an incredibly informative video from Bizarre Beasts detailing the evolutionary development of the argonaut, the only octopus with a shell, and the only one that lives in the open ocean, unlike the rest of its

This is a video of pet octopus Marty (who I believe is an Octopus bimaculatus, aka Verrill’s two-spot octopus) opening a closed jar just moments after being exposed to one for the first time. That’s impressive. How we knew to turn it is beyond me, and certainly beyond my roommate,

An unmanned submersible launched by the research vessel EV Nautilus near Papau (southeast of the Philippines) captured some footage of the boat’s namesake on its last underwater exploration of 2024. If there was ever proof that aliens exist, the nautilus makes a pretty solid argument. Just look at that thing!

This is some footage from the Monterey Bay Aquarium Research Institute (MBARI) of Bathydevius caudactylus, aka the mystery mollusc. It lives in the midnight zone (1000 – 4000m) of Monterey Bay, and is recognized as a swimming sea slug. But can it really be a slug if it can swim?

This is a video from a depth of 3,300 meters (10,827 feet — more than 2 miles) in the Tonga Trench (the second deepest trench behind the Mariana) between new Zealand and Fiji of a rarely seen Bigfin squid (misnomer, should have been named Longleg Squid) trolling its 13-foot tentacles

Just in time for spooky season comes the announcement of a new species of ‘ghost shark’ (actually a chimaera or spookfish, but closely related to sharks and rays), found in the ocean depths off Australia and New Zealand. Looking suspiciously like Zero from The Nightmare Before Christmas, the ocean ghost

This is a short video of a stone crab “stealing” diver Duran Roberts’s camera in The Bahamas and trying to make a run scuttle for it. It then attempts to fight Duran for the camera when he tries to take it back. But was the camera actually stolen, or did

Because nature is totally nuts, this is a video of a robotic spy fish infiltrating a millions-strong shoal of herring while they look for a place to lay and fertilize their eggs. The real fish constantly release flatulence from their swim bladders that sounds like clicking underwater, a behavior our
