Reddish-brown coarse fur; barrel body; blunt snout; almost no external tail.

Skull, Dentition & Jaw

Large flat skull with ever-growing rodent incisors.

Eyes, Pupils & Facial Discs

Eyes, ears, and nostrils high on head for seeing/breathing while mostly submerged.

Paws, Claws & Ears

Short legs with partially webbed feet.

Tail & Spoor Dynamics

Vestigial — appears tailless.

Sexual Dimorphism

Subtle; males have a larger scent gland (morrillo) on the snout.
