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

Početna

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

Što jede?

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

Što radi njegov otrov kad ugrize ili ubode?

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

Koliko je opasno za ljude?

Opasnost za ljude: BolnoMože jako boljeti, ali gotovo nikad nije ozbiljno.

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

Što radi kad se uplaši?

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

Ako ubode

Stavi ranu u vruću vodu, toliko vruću koliko osoba može podnijeti bez opeklina (provjeri je vlastitom rukom), na 30 do 90 minuta. Potraži liječničku pomoć, osobito kod ribe kamena i raža.

Uvijek prvo nazovi broj za hitne slučajeve (112, 000, 911). Ovo su opće upute za prvu pomoć, a ne liječnički savjet. Osnove prve pomoći

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ubode: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice

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

Razbijač mitova

Mit: Stingrays attack people in the water.

Istina: 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
