The short-tail stingray is one of the largest stingrays in the world. It lives in temperate seas off southern Africa, southern Australia and New Zealand, mostly on or near the sea floor. It is not aggressive, but its long venomous sting can cause a serious wound if the ray is startled.1

It lives on the bottom in estuaries, sheltered bays, sandy flats, rocky reefs and the outer continental shelf, and sometimes swims up into open water. Off southern Africa it is usually found offshore, at depths of 180 to 480 m. Off Australia and New Zealand it can be found from the intertidal zone down to 156 m. At Hamelin Bay in Western Australia, many rays gather where visitors hand-feed them fish scraps.1

Ano ang kinakain nito?
It eats bony fishes and invertebrates such as molluscs and crustaceans, including burrowing species. It finds buried bivalves and spoon worms by detecting the tiny water jets they produce, then sucks them out of the sediment. It also eats open-water animals such as salps and hyperiid amphipods.1

Paano ito makikilala

  • Diamond-shaped, heavy disc that is smooth, with no scales (dermal denticles) on the disc even in adults1
  • Plain grey-brown back, darkening towards the tail and above the eyes, with a line of white pores on either side of the head1
  • Whitish underside, darkening towards the edges of the fins1
  • Tail usually shorter than the disc, thick at the base, with one or two serrated stinging spines about halfway along it1
  • Adults have a row of large, spear-like thorns in front of the sting1

Madalas mapagkamalang: The pitted stingray (Dasyatis matsubarai) of the northwestern Pacific looks similar but is smaller. Records of this species from northern Australia and Thailand are thought to be other rays that were misidentified.1

Mga tusok

Lumalabas ang kamandag sa pamamagitan ng pantusok.

Ano ang epekto ng kamandag nito?

Its sting is venomous. The mucous sheath covering the sting contains a toxin that causes necrosis, which means the death of body tissue. The most dangerous injuries involve damage to a vital organ, heavy blood loss, or secondary infection (sepsis) or tetanus.1

Gaano ito kapanganib sa tao?

Panganib sa tao: NapakapanganibKaya nitong pumatay ng taong hindi nagamot.

The short-tail stingray is not aggressive, but if startled or harassed it can inflict a serious and even fatal wound. Its sting can be over 30 cm long and can penetrate most footwear, including kevlar bootees. It is responsible for most stingray injuries off New Zealand, including the death of Australian naturalist Steve Irwin, who was pierced in the chest by its barbed tail.1

Ano ang ginagawa nito kapag natatakot?

When threatened, it raises its tail over its back like a scorpion, and a startled ray can leap through the water and strike with its tail.1

Kung tumusok ito

  • Ilubog ang sugat sa mainit na tubig, kasing-init ng kayang tiisin ng tao nang hindi napapaso (subukan muna gamit ang sarili mong kamay), sa loob ng 30 hanggang 90 minuto. Kumuha ng tulong medikal, lalo na para sa stonefish at pagi.

Laging tawagan muna ang numero pang-emergency (112, 000, 911). Ito ay pangkalahatang gabay sa pangunang lunas, hindi payong medikal. Mga batayan ng pangunang lunas

Mag-ingat

  • Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
  • Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
  • Kung tusukin ka ng isa: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.

Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat

Mga fact

1

It can flap its pectoral fins with enough force to make a loud audible 'bang' in the water, although it is usually slow-moving.1

2

It is one of the largest stingrays in the world, and reliable observers off New Zealand have reported individuals almost 3 m across.1

3

Captive experiments suggest it can detect magnetic fields, which may help it navigate.1

4

Every summer, large groups gather under the rocky archways of the Poor Knights Islands off New Zealand, where both mating and birthing have been seen.1

5

Captive females have been observed mating with up to three different males in succession.1
