(The swampus or swampus octopus is a species of amphibious octopus native to the Bengal Swamp of 100 million AD. The swampus has evolved to survive on land, though for limited periods of time. Unable to breathe properly out of water, it relies on finite oxygen stores within its tissues and blood. Once these reserves have been depleted, the swampus must return to the water to replenish its oxygen supply.)
