Rhizolos

Information
Rhizolos are small monsters that swim in the thick mud and muck of the swamp looking for prey and carrion even constantly patrolling the muddy waters of their territory for food.

Taxonomy
Order:Rhizodontidae - Suborder: Muck Swimmers - Family: Rhizolos.

Habitat Range
They evolved to swim in the thick muddy waters of the Swamps so can't survive in any other areas.

Ecological Niche
Rhizolos feed on small animals like frogs and fish but will swim in muck to sneak and prey on weak or sick animals but these predators are far from the top of the food chain being preyed on by larger swamp predators.

Biological Adaptations
They have the ability to swim through thick mud that most creatures can't handle, and have very primitive limbs that they use to crawl on the ground to move from muck pool to muck pool.
