Blanket Octopuses Rip the Poisonous Arms of Portuguese Man O’Wars
There are many unusual, frightening creatures in the ocean that are more than capable of protecting themselves in various ways. You don't want to get into contact with too many creatures of the deep blue water, from the jaws of a shark to the claws of a crab. Some of the most powerful organisms rely on a variety of deadly and incapacitating toxins that can quickly and effectively stop a predator, including a human.
A backdoor to its compromised defenses has been created by the blanket octopus. A blanket octopus doesn't produce powerful venom, unlike the dangerous blue-ringed octopus. Instead, they will take the Portuguese man of war's weaponry.
The man of war has venomous, stinging tentacles and is sometimes misidentified as a jellyfish even though it is actually a siphonophore. Although they rarely kill people, they can nevertheless result in blisters and welts and are potent enough to kill small fish. But blanket octopuses are resistant. They will immediately rip the tentacles off the man of war and use them as poisonous whips to either attack or defend themselves.
