Descendants of octopi, swampi live in the brackish Bengal swamp, formed when Africa merged with Australasia and blocked the Bay of Bengal, in 100 million A.D. They have a deadly venomous bite that can even kill a baby toraton. Unfortunately for the swampus, adult toratons have no predators and are not affected by their venom.

Predators:

One of the few creatures capable of killing a swampus is the lurkfish, which uses the electric field surrounding its body to stun the swampus.

The amazing thing about the swampus is that it is the first cephalopod to venture out onto land. Infant swampuses are nurtured in a leafy plant named the Nursey Vase filled with fresh water, into which the mother urinates to maintain the proper salinity. Four of the swampus' arms have changed into four individual snail-style foot-muscles, and its mantle cavity can also be used as a lung, allowing it to stay out of water for up to four days. One male will mate with three females and help raise their young. When the young swampus are ready to leave their nest the mother will escort them to the shore and see them a safe journey. They do this to save their young from the lurkfish.
