Phylum: Chordata
Class: Chondrichthyes (cartilaginous fish)
Order: Rajiformes
Family: Rajidae
Scientific name: Raja laevis
French name: Grande raie

Weight: 14 to 17 kg
Status: Common species

Distinguishing features: This skate has a flattened body, a pointed snout and fairly smooth skin. There are several mucous pores marked with black spots on its ventral surface, and several rows of spines on its tail.

Reproduction: Spawning occurs in winter. Fertilization is internal. The eggs of the barndoor skate are encased in yellowish capsules that are 12.7 cm long and 7 cm wide.

Diet: These fish eat invertebrates, including bivalve molluscs, crabs, lobster, shrimp and worms. They also eat various types of fish, including spiny dogfish, gaspereau, herring, sea lances and flatfishes.

Predators: Their main enemies are large sharks.

Habitat: Barndoor skates live in salt water on various types of bottoms. They tolerate a wide range of temperatures, from 1.2 to 20°C. They are found in shallow water, along the continental shelf, down to 750 metres.

behaviour: These voracious predators have few enemies. At rest, barndoor skates are camouflaged against the bottom. They use their sensitive snouts to forage in the sand or mud. The spiracle, a small hole located behind each eye, is used to take in water and avoid blocking the gills.
