The southern stingray is a flat, diamond-shaped fish that lives on the sea bed in warm waters of the western Atlantic Ocean. It hides under sand and mud and is famous for the venomous spine on its tail. Divers and snorkellers often meet it in the Caribbean.1

The barb on the tail is covered in venomous mucus. The spines are not fatal to humans, but stepping on one causes intense pain.1

Ana hatari gani kwa watu?

Hatari kwa watu: MbayaKudungwa kunahitaji daktari. Vifo ni nadra sana.

The spines are not fatal to humans, but they are incredibly painful if stepped on. They are used to defend the stingray against predators, including humans.1

Hufanya nini akiogopa?

It buries itself in the sea bed to avoid predators and uses its venomous tail spines to drive them off.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

In shallow waters, birds follow the stingrays as they dig, eating the fish that the stingrays uncover.1

Its eyes and breathing openings sit on top of its head, so it can take in water while lying on the sea bed or buried in sand.1

It senses hidden prey through Ampullae of Lorenzini, which pick up the electric fields that prey give off.1

It is nocturnal, so most of its hunting happens at night.1

Female southern stingrays grow much larger than males.1
