Stingray
A diverse group of cartilaginous rays with venomous tail spines.
Stingrays are a suborder of cartilaginous fish comprising about 220 species across eleven families. They inhabit coastal, deep, and fresh waters globally, using flattened bodies to ambush prey on the sea floor. Many species face threats from unregulated fishing, with dozens listed as vulnerable or endangered.
- About 220 known species in 11 families
- Use electroreceptors to find buried prey
- Venom stored in tissue cells, not glands
- Can store sperm for delayed birth
- 45 species listed as vulnerable or endangered
What it is
Stingrays belong to the suborder Myliobatoidei, a group of cartilaginous fish related to sharks. There are approximately 220 known species divided into eleven families, including eagle rays, butterfly rays, and river stingrays. Their bodies are flattened, allowing them to blend into sandy sea floors. Most have a venomous spine on their tail for defense. They vary greatly in size and shape, from the broad wings of eagle rays to the compact forms of round stingrays.
Where it lives
These fish are common in tropical and subtropical coastal waters around the world. Some species, like the thorntail stingray, live in warmer temperate oceans, while others, such as the deepwater stingray, inhabit the deep ocean. River stingrays and certain whiptail species are restricted to fresh water habitats. While most are demersal, living near the bottom, pelagic species like the eagle ray swim in open water columns.
How it lives
Stingrays are often ambush hunters that bury themselves in sediment to wait for prey. They use electroreceptors called ampullae of Lorenzini to detect electrical signals from hidden animals. Their diet mainly consists of mollusks, crustaceans, and small fish. Freshwater species may eat insects, while large pelagic rays filter plankton. They use suction to pull prey under their bodies before crushing it with powerful jaws adapted for hard shells.
Breeding and life cycle
Stingrays are ovoviviparous, meaning they bear live young without a placenta. Embryos initially feed from a yolk sac, then receive uterine milk from the mother. Litters typically contain five to thirteen pups. Mating can be prolonged, lasting months in some species, driven by hormonal changes. Females may store sperm for extended periods, giving birth when conditions are favorable. Young usually swim away immediately after birth.
Fish and people
Stingrays are eaten in many coastal regions, such as Malaysia, Singapore, and India, where they are grilled or curried. The wings, cheeks, and liver are prized, while other parts are often too rubbery. They possess a venomous spine that causes painful injuries if stepped on. Fatalities are rare but possible if the spine pierces vital organs. Unregulated fishing has threatened many species, leading to conservation concerns.
Status and threats
Many stingray species are becoming threatened due to unregulated fishing. As of 2013, the International Union for Conservation of Nature listed 45 species as vulnerable or endangered. The status of other species remains poorly known, resulting in data deficient classifications. Conservation efforts are needed to address population declines caused by overfishing and habitat loss.
Questions people ask about Stingray
Are stingrays dangerous to humans?
Stingrays are not aggressive and usually only sting when stepped on. The venom causes pain and swelling but is rarely life-threatening unless it hits a vital organ. Fatalities are extremely rare.
What do stingrays eat?
Most stingrays feed on mollusks, crustaceans, and small fish. They crush hard shells with powerful jaws. Pelagic species like mantas filter plankton, while freshwater rays may eat insects.
How do stingrays reproduce?
They are ovoviviparous, bearing live young. Embryos feed on yolk sacs and uterine milk. Litters range from five to thirteen pups. Some females can store sperm for months before giving birth.
