Lutrimimus smilodontis

Lutrimimus smilodontis or "Sabakti" (Fish-Dog) are inhabitants of fish-rich waters of the Isle Nonaless. This strange animals are descendants of th rodent family Muridae. In difference to the small rodents like rats or mice, the flesh-eating Deinincisivis arborealis, the piglike Myoporcellus-species or even the baboon-rats of the genera Cachinnus and Papillocephalus, this animal is specialized in hunting and eating fishes. For this lifestyle the bodyplan of the rodent has changed much.
The four Incisivi grew into sabertooth for grabbing slippery prey, the short strong limbs grew webbings, while the useless tail was reduced into a stub.
