Skates
Skates (pronunciation: /skeɪts/) are a type of fish belonging to the family Rajidae in the superorder Batoidea of rays. More than 150 species have been described, in 17 genera. They are found worldwide in temperate and arctic waters.
Etymology
The term "skate" is derived from the Old Norse word "skata".
Anatomy
Skates have a flattened body and large pectoral fins extending from or nearly from the snout to the base of the tail. The dorsal fins are located toward the tail. The skin of skates is covered with tiny, tooth-like scales called Dermal denticles.
Diet
Skates feed on various types of bottom-dwelling organisms. Their diet includes invertebrates such as crustaceans, mollusks, and polychaetes.
Reproduction
Unlike most fish, skates reproduce by producing egg cases that are often called "mermaid's purses".
Conservation
Many species of skates are currently threatened due to overfishing and habitat loss. They are often caught as bycatch in commercial fisheries.
