Stingray

Presentation

The Stingray is a cartilaginous fish with a flattened, disc-shaped body, equipped with a long, thin tail armed with one or more venomous spines. It belongs to the group of batoids, close relatives of sharks. This term actually designates several species of the Dasyatidae family distributed in temperate and tropical seas, as well as certain brackish or fresh waters. It generally lives on sandy or muddy bottoms, half buried, where it feeds on small invertebrates. Discreet and non-aggressive, it only stings if it feels threatened or trampled.

The diamond- or disc-shaped body is dorsoventrally flattened, with pectoral fins fused to the head forming flexible wings. The tail, thin and whipping, bears one or more serrated prickles connected to venomous glands. The dorsal color is often gray, brown or sandy, while the belly is light, a camouflage suitable for life on the bottom. The eyes and vents (spiracles) are located on the top of the body, the mouth and gill slits below.

Characteristics

Indicative values: they vary by subspecies, sex and region.

Habitat and distribution

Stingray mainly frequents sandy or muddy bottoms of shallow coastal areas, lagoons and estuaries. Some species tolerate brackish water, or even migrate upstream into freshwater rivers in the tropics. It likes sheltered areas where it can easily burrow into the loose substrate.

Behaviour

A rather solitary animal, the Stingray spends a large part of its time immobile, partially buried in the sand. It can group together seasonally during migrations linked to reproduction or the search for food. Its behavior is generally fearful towards humans, the sting only occurring in the event of accidental contact, often when a swimmer steps on it.

Reproduction

Reproduction is ovoviviparous: the eggs develop inside the body of the female and the young are born already formed, completely autonomous. Gestation generally lasts several months depending on the species. The number of young per litter is low, often between two and ten individuals.

Peculiarities

The caudal sting, covered with a venomous sheath, serves exclusively for defense and not for hunting. Some species of stingrays are among the largest rays in existence, with a disc that can exceed two meters wide. The sting wound is painful and may require medical attention, although fatal accidents remain rare.

Threats and conservation

Overfishing, particularly bycatch in nets and trawls, poses the main threat to many stingray populations. Degradation of coastal habitats, such as mangroves and sandy bottoms, also reduces their breeding and feeding areas. Certain species are also sought after for their skin or flesh, increasing fishing pressure.
