COMPARISON WITH OTHER SPECIES
Sharing most of its habitat with a cat shark, star Cunha shark (Mustelus asterias) is a benthic predator. Combing through flocks millionie zone at a depth of 100 m, mustelids sharks prey on crustaceans, such as crabs and lobsters, and fish. In their diet can also include leopard sharks, as in length, they barely reach half the length of Kunia sharks. The star Kunia sharks well-marked dorsal and pectoral fins, typical for big sharks and make it a more threatening silhouette. It got its name because of overlapping rows of scales on the skin, making it smoother than other shark species. Eggs star sharks develop inside the body of the female, and the pups are born alive — unlike leopard sharks, which lays eggs on the bottom of the sea.
The majority of species found in coastal waters worldwide, including the Mediterranean and Chernomora. Missing in the seas of the Arctic and Antarctic. Some species are found in deeper waters.

• Small, bottom-dwelling sharks, preying on fish, mollusks and other invertebrates.
• During mating, the male wraps completely around the female, before to carry out internal fertilization.
• Large single eggs, protected individual leathery, attached to the seabed using a thin, twisted flagella.
• Floating, wriggling, above the seabed in search of food, cat shark relies on its spotted coloring, masking it from the sand and hide from predators.
Like other sharks, the skeleton of the cat sharks consists of cartilage. This material is so flexible that allows fish to fold-
