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

Domov

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

Kaj je?

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

Kako jo prepoznaš

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

Moč strupa

Piki

Strup pride ven skozi želo.

Kaj naredi njen strup, ko ugrizne ali piči?

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

Kako nevarna je za ljudi?

Nevarnost za ljudi: BolečeLahko zelo boli, a skoraj nikoli ni resno.

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

Kaj naredi, ko se prestraši?

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

Če piči

Rano daj v vročo vodo, tako vročo, kot jo poškodovanec prenese, ne da bi se opekel (preizkusi jo s svojo roko), za 30 do 90 minut. Poišči zdravniško pomoč, še posebej pri kamnitih ribah in morskih bičih.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te piči: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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

Razbijalec mitov

Mit: Stingrays attack people in the water.

Resnica: 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
