Kuhl's maskray is a flat, diamond-shaped stingray with green skin and blue spots. It lives on sandy and muddy seabeds in warm coastal waters from Indonesia to Japan and around most of Australia. Its tail has venomous spines, so it is important to know what it looks like and to keep a safe distance.1

Nguvu ya sumu

Kudungwa

Sumu hutoka kupitia mdungo.

Sumu yake hufanya nini?

The venom contains serotonin, 5' nucleotidase and phosphodiesterase. These are active compounds that act on the body's tissues.1

Ana hatari gani kwa watu?

It is very venomous. Its barb can be about 30 cm long.1

Hufanya nini akiogopa?

Its bright colouring warns predators of its venomous spines. It buries itself in sand to hide from predators.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

Large sharks such as hammerhead sharks prey on it. A hammerhead pins it down with its head while the ray is in shock and much weaker.1

Its tail is about twice as long as its body and carries two venomous spines.1

Unlike most stingrays, which bury themselves to hunt, Kuhl's maskray buries itself in sand only to hide from predators.1

Its skin is used to make drums, such as the Arab and Turkish darbuka goblet drum and the riq tambourine.1

Two short peptides found in its hydrolysed proteins have shown protective effects against the oxidation of lipids, DNA and proteins. They may be useful as functional food ingredients or nutraceuticals.1
