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 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.
