Two southern stingrays swim over the sea bed

Stingrays

Stingrays are a family of cartilaginous fish containing nine genera and about 70 species. They can be found in all tropical and sub-tropical seas, and there is also a freshwater-only sub-family - the river rays. A flattened body shape and disc-shaped pectoral fins help stingrays live and hide in sand and mud underwater. The famous barbed stinger on the tail is only used in self-defence, often when they are stepped on in shallow waters.

Scientific name: Dasyatidae

About

Stingrays are a group of rays, which are cartilaginous fishes related to sharks. They are classified in the suborder Myliobatoidei of the order Myliobatiformes, and consist of eight families: Hexatrygonidae (sixgill stingray), Plesiobatidae (deep water stingray), Urolophidae (stingarees), Urotrygonidae (round rays), Dasyatidae (whiptail stingrays), Potamotrygonidae (river stingrays), Gymnuridae (butterfly rays), and Myliobatidae (eagle rays).

Most stingrays have one or more barbed stings (modified from dermal denticles) on the tail, which are used exclusively in self-defense. The stinger may reach a length of approximately 35 cm (14 in), and its underside has two grooves with venom glands. The stinger is covered with a thin layer of skin, the integumentary sheath, in which the venom is concentrated. A few members of the suborder, such as the manta rays and the porcupine ray, do not have stingers.

Stingrays are common in coastal tropical and subtropical marine waters throughout the world, and also includes species found in warmer temperate oceans, such as Dasyatis thetidis, and those found in the deep ocean, such as Plesiobatis daviesi. The river stingrays, and a number of whiptail stingrays (such as the Niger stingray), are restricted to fresh water. Most myliobatoids are demersal, but some, such as the pelagic stingray and the eagle rays, are pelagic.

While most stingrays are relatively widespread and not currently threatened, for several species (for example Taeniura meyeni, D. colarensis, D. garouaensis, and D. laosensis), the conservation status is more problematic, leading to them being listed as vulnerable or endangered by IUCN. The status of several other species are poorly known, leading to them being listed as Data Deficient.
