Strangling octopuses on Wetpixel

A new paper by Christine Huffard and Mike Bartick has been published in the journal Molluscan Research. Entitled “Wild Wunderpus photogenicus and Octopus cyanea employ asphyxiating ‘constricting’ in interactions with other octopuses, it catalogs several instances in which “aggressive constriction” has been seen in an instance of apparent sexual cannibalism and in an attempt to eliminate a competitor for a food source.
