We know you have been thinking where you can aquire a hexapus for your reef aquarium. You thought about a octopus, but that is so 1990’s. Recently, “caretakers at a British aquarium recently discovered that one of its newest residents, an octopus named Henry, had six legs instead of the usual eight.” This is the first one ever discovered in the world. Pretty neat eh? Seems the reason why his limbs are missing is about a genetic mutation.
