Unlucky Octopus

Check out this brutal video from Roy Caldwell’s Lab at UC Berkeley. It shows the ‘interaction’ between a mantis shrimp (Odotodactylus scyllarus) and a blue-ringed octopus (Hapalochlaena lunulata), when the latter is introduced into the mantis shrimp’s tank. Both of these animals occur amongst coral reef rubble in the Western Pacific, so it’s possible that they often meet in the wild. Take a look at what happens when they do…

Well, that didn’t go so well for the unfortunate octopus. Take that, squishies!

It’s unknown how the stomatopod copes with the venom of the blue-ring as it kills and devours the cephalopod.

You can learn more about keeping your own murderous mantis shrimp at Roy’s List.
