Skate (fish)

Skate (fish) is a term used to refer to a group of cartilaginous fish belonging to the family Rajidae within the superorder Batoidea of rays. More than 150 species of skates live in oceans worldwide, from shallow coastal waters to deep abysses.

Anatomy and Appearance

Skates are characterized by their flat bodies and wing-like pectoral fins which are attached to their heads, giving them a distinct, ray-like shape. Their bodies are covered in rough, tooth-like scales called dermal denticles. Unlike rays, skates have a prominent dorsal fin.

Diet and Behavior

Skates are carnivorous, feeding on a variety of organisms such as crustaceans, mollusks, and small fish. They are benthic creatures, spending most of their time on the ocean floor. Skates are known for their unique method of reproduction, laying eggs in hard rectangular cases often referred to as "mermaid's purses".

Commercial Importance

Skates are commercially fished worldwide, primarily for their wings. The meat is considered a delicacy in many cultures. However, overfishing has led to a decline in skate populations, raising concerns about their conservation status.

Conservation Status

Many species of skates are currently listed as endangered or threatened by the IUCN. Overfishing and habitat destruction are the primary threats to skate populations.
