Dasyatis Pastinaca
The common stingray (''Dasyatis pastinaca'') is a species of stingray in the family (biology), family Dasyatidae, found in the northeastern Atlantic Ocean and the Mediterranean Sea, Mediterranean and Black Seas. It typically inhabits sandy or muddy habitats in coastal waters shallower than , often burying itself in sediment. Usually measuring across, the common stingray has a diamond-shaped pectoral fin disc slightly wider than long, and a whip-like tail with upper and lower fin folds. It can be identified by its plain coloration and mostly smooth skin, except for a row of tubercles along the midline of the back in the largest individuals. The predominant prey of the common stingray are benthic, bottom-dwelling crustaceans, though it also takes molluscs, polychaete worms, and small bony fishes. It is aplacental viviparous: the embryos are nourished by yolk and later histotroph ("uterine milk") produced by the mother. Females bear 4–9 young twice per year in shallow water, after ...
