A biologically plausible semi-aquatic mammal resembling a catfish-like beaver. Elongated torpedo-shaped body, very short dense dark fur, thick insulating fat layer. Broad flattened head with strong beaver-like incisors, short mammalian whiskers around the mouth, no scales. Small side-set eyes, minimal external ears. Four short powerful legs with webbed feet. Large laterally flattened tail similar to a beaver, used for propulsion. Realistic anatomy, natural proportions, no fantasy or monster features. Environment: murky river or lake, underwater scene with plants and submerged wood, soft filtered light. Scientific wildlife illustration, ultra-detailed, photorealistic, high resolution. See more
