Captured on video by the Schmidt Ocean Institute’s remotely operated submersible SuBastian, this is the first ever video of a colossal squid (Mesonychoteuthis hamiltoni) in its natural habitat. The juvenile squid was filmed at a depth of 600m in the South Sandwich Islands (I love sandwiches) about 1,100 miles northeast

Seen here looking like something a child would produce if you asked them to draw a nightmare, this is a video of a rarely seen humpback anglerfish (Melanocetus johnsonii) spotted in shallow waters off Spain’s Canary Islands. The fish typically lives some 1,500m (~1 mile) deep in the pitch-blackness, but

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
