Another name for a dogfish is a spiny dogfish or sometimes a mud shark. It's a small type of shark found in oceans around the world.
Dogfish have a slender body with a pointed snout, large eyes, and sharp teeth. They are typically gray or brown in color with a lighter underbelly. They have two dorsal fins and are known for their scavenging behavior.
The kidneys of a dogfish shark, like those of other elasmobranchs, are elongated and flattened, resembling a pair of ribbon-like structures. They are located along the dorsal side of the body, running parallel to the spine. In dogfish sharks, the kidneys are typically dark in color and have a smooth, firm texture. Their structure is adapted for osmoregulation, helping the shark manage salt and water balance in its marine environment.
