Blanket Octopus by ccris393. The male Blanket Octopus rips off tentacles of the Portuguese Man o’ War and holds them for its own protection. This is true. The males of genus Tremoctopus are very small and different compared to the huge, veiled females (a phenomenon known as sexual dimorphism) and have to rely on stolen tentacles of man o wars (Physalia), which carry powerfully stinging nematocysts.
