On Wikipedia

Squalidae, also called dogfish sharks, dog sharks, or spiny dogfish, are a family of sharks in the order Squaliformes. Dogfish sharks make up the second largest order of sharks at 119 species. They have two dorsal fins, each with smooth spines, but no anal fin, and their skin is generally rough to the touch. Dogfish tend to have slender bodies with a pointed snout. These species are also known to be more compact in comparison to other sharks. As the species reaches adulthood, males usually measure a maximum of 39 inches (990 mm), while females typically measure 49 inches (1,200 mm) long. The species therefore exhibits female-dominant sexual dimorphism. Dogfish sharks earned their name after a group of fishermen observed the species chasing down smaller fish in dog-like packs.Dogfish sharks…
