Common Stingray Dasyatis Pastinaca Razza Ray Trigone intotheblue.it
As soon as I entered the water for a swim with the snorkel and the mask I met three specimens of Ray of the species Trigone Dasyatis Pastinaca, commonly known as Pastinaca. All three of the same size, about 25/30 cm, after a while ‘are left to approach and film rather closely. The meeting took place in the Masua sea in South-Western Sardinia, on a backdrop mixed with sand and posidonia in a few meters of depth.

The stingray, a breed belonging to the family Dasyatidae, Class Chondrichthyes, is widespread in the North Atlantic Ocean and in the Mediterranean, from Norway to the Baltic Sea to the Canaries and the Black Sea. The ideal habitat is represented by sandy and silty bottoms, where this animal hides and feeds.
