What are stingrays?
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.
[4] 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.
