The serrated spine is potentially dangerous, and the cowtail stingray is regarded as particularly dangerous to handle.1

Hufanya nini akiogopa?

When threatened, it flees at a 45° angle away from the predator, keeping the predator in view while covering distance.1

Akidunga

Weka jeraha kwenye maji ya moto, moto kiasi ambacho mtu anaweza kuvumilia bila kuungua (pima kwanza kwa mkono wako), kwa dakika 30 hadi 90. Tafuta msaada wa kitabibu, hasa kwa samaki-jiwe na taa.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

A cowtail stingray was recorded in the Ganges River about 2,200 km (1,400 mi) from the sea.1

Resting groups of cowtail stingrays often form a rosette, with their tails pointing outward so they can see threats from every direction.1

Its large, regularly arranged skin bumps have made it a source of shagreen leather since ancient times.1

The cowtail stingray and reticulate whiprays often form mixed-species groups, probably because the whiprays detect predators well thanks to their long tails.1

Its tail fold and tail tip are black, and the tail carries sensors that act as a secondary warning system.1

Newborn cowtail stingrays have completely smooth skin, and their denticles develop quickly after birth.1
