The pelagic stingray is a ray that lives in the open ocean rather than on the sea floor, which sets it apart from almost all other stingrays. It is found in warm waters around much of the world. It can give a severe sting with its tail spine, so it matters most to people who work on fishing boats.1

  • The pectoral fin disc is a thick, wedge-shaped wing that is about one-third wider than it is long.1
  • It is a plain dark purple to blue-green above, with a slightly lighter shade below.1
  • The tail is whip-like, up to twice as long as the disc, with an extremely long, serrated spine about a third to halfway along it.1
  • Young rays are smooth-skinned, and small prickles and thorns appear with age.1

Tge fa ses tissi?

The venom is on the tail spine and is quite potent, which is why other fishes avoid it.1

Quant privlus è el per umans?

Privel per umans: GravIna piztgada sto vegnir tractada dad in medi. Cas da mort èn fitg rars.

It is rarely encountered except by fishery workers. Its tail spine can inflict a severe wound that can be fatal.1

Tge fa el, cura ch'el ha tema?

When captured and handled, it releases a thick black mucus that covers its body, and its tail spine delivers venom.1

Fatgs

1

It is the only stingray that almost exclusively lives in the open ocean rather than on the sea floor.1

2

Instead of rippling the edges of its disc like other stingrays, it swims by flapping its pectoral fins, similar to eagle rays.1

3

Both sexes have pointed teeth, which is unusual among stingrays. Only the teeth of adult males are longer and sharper.1

4

Females can store sperm inside their bodies for more than a year, waiting for good conditions before their young develop.1

5

A captive female reached 94 cm across and 49 kg, the largest individual on record from a rearing experiment.1

6

Oceanic whitetip sharks, great white sharks and toothed whales prey on it.1
