Rare footage shows unusual octopus and puffer fish interaction

Divers encountered a strange fight between an octopus and a pufferfish, off Fregate Island in the Seychelles. The octopus appears to be trying to make a meal of the fish, but is that even possible? While octopuses have the capacity to eat creatures small and large, they usually don’t eat fish—especially poisonous ones. Pufferfish are filled with tetrodotoxin, a neurotoxin hundreds of times more potent than cyanide. However, no one knows how this affects octopuses. In addition to this chemical defence pufferfish are covered in spines. Octopuses' arms, however, are nimble and malleable, able to wrap around sharp edges without injury. The divers had to leave the scene before seeing the final outcome, so scientists can only speculate which of the two came out alive.

Watch 1,000 ‘Octo-mums’ in World’s Largest Deep-sea Octopus Nursery

This is an octopus nursery unlike any observed before. The octopuses appear inside-out because they are in a brooding posture. Mothers wrap their arms around their bodies and their eggs to protect them. Around 1,000 octopuses were observed, and nearly all appeared to be brooding. The Muusoctopus robustusis a deep-sea species rarely observed. This is only the second deep-sea octopus nursery on record – the first was discovered off Costa Rica in spring 2018.

Rare Dumbo Octopus Shows Off For Deep-sea Submersible

Commonly called a ‘dumbo’ octopus, this deep-sea cephalopod has lateral fins that resemble big ears. Little is known about the ghostly white Grimpoteuthis octopus's behaviour, because it's rarely observed. Crew aboard the E/V Nautilus had an exciting encounter with the rare, ghostly white cephalopod. The Nautilus is surveying an unexplored area of Davidson Seamount, an inactive volcano. The rocky habitat hosts large coral forests, sponge fields, and abundant unidentified species.

Watch an Octopus Hitch a Ride on a Diver’s Arm

This creature hitched a ride on a diver off the coast of Cannes, France. It camouflaged to match the arm it was hugging. It's not unusual for an octopus to inspect a diver. Each sucker may contain 10,000 neurons used to feel and taste. This octopus was probably curious, and the diver did a good job to stay calm and let the octopus leave on its own accord.
