The yellow stingray is a small ray that lives on the sandy, muddy or seagrass bottoms of shallow coastal waters in the western Atlantic, the Gulf of Mexico and the Caribbean. It spends much of the day buried under sand or lying still. It can sting with a venomous spine on its tail, but it usually ignores divers unless it is stepped on or provoked.1

Leef in

Western Atlantic: Gulf of Mexico and Caribbean Sea, from North Carolina to Trinidad, including Florida and the Bahamas1

Atlantiese Oseaan, Karibiese See, Golf van Meksiko

Tuis

It lives in bays, lagoons, estuaries and low-energy surf zones, from the water's edge down to 25 m deep. It likes hard, rocky bottoms covered in small sea creatures, and also sand, mud and seagrass, sometimes near coral reefs. People are most likely to meet it in shallow water while diving or wading.1

Wat eet dit?

It eats small invertebrates such as shrimps, and probably worms, clams and small bony fishes. It often settles on prey and traps it against the bottom, then moves it to its mouth with its disc. It may also wave the edges of its disc to dig pits and uncover buried prey.1

Hoe om dit te herken

Nearly round pectoral fin disc with a short tail and a small, leaf-shaped tail fin.1
Pattern of spots and blotches, either light on dark or dark on light, which varies a lot between individuals.1
Can quickly change the tone and contrast of its colour to match its surroundings.1
Underside is yellowish, greenish or brownish white, with small darker spots near the edge of the disc and the tail.1
A serrated spine sits about halfway along the tail.1

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

The tail spine is coated in potent venom. The wound it causes is extremely painful, but it is seldom life-threatening.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

It is not aggressive towards people. It injures people only when it is stepped on or otherwise provoked, and the resulting wound is very painful but seldom life-threatening.1

Wat doen dit as dit bang is?

When threatened it mostly stays still, buried under sediment or lying in vegetation, and if stepped on or provoked it defends itself with its tail spine.1

As dit steek

Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand (toets dit met jou eie hand), vir 30 tot 90 minute. Kry mediese hulp, veral vir klipvisse en pylsterte.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

die moeite werd om te weet

Feite

It glows green when lit by blue or ultraviolet light, a effect called biofluorescence that may help it communicate and camouflage itself.1

It can raise the front of its disc to form a shaded 'cave' that draws in small creatures looking for shelter.1

Off Jamaica, up to one yellow stingray per square metre gathers under mangrove roosts used by cattle egrets, possibly because bird droppings feed the small animals that attract the rays.1

Its eyes give it a 360° view of its surroundings, and each eye has a covering that controls how much light enters.1

It can live for 15 to 25 years.1

Mite-breker

Mite: Stingrays attack people in the water.

Waarheid: Yellow stingrays generally pay little attention to divers and can be approached closely. They only sting when they are stepped on or otherwise provoked.1
