SwampDragon

Although too fat and clumsy to move well at all on land, only spending time there to relax and digest copious amounts of prey - it really is an apex predator in the murky waters where it resides, being a fast and powerful swimmer. It being around the size of an adult hippo, the creature will with the help of a massive mouth eagerly swallow up any prey able to fit, in mere seconds.

Quite a few divers, and even the occasional diving party, have seen their expeditions end rather unfortunately - in the bloated gut of the swamp dragon.
