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

Leef in

Indonesia to Japan, most of Australia, Kenya, Madagascar, Mauritius, Somalia, South Africa's east coast, India and much of Asian coastal waters1

Indiese Oseaan, Stille Oseaan, Koraalsee, Andamansee, Suid-Chinese See, Filippynse See, Timorsee & Arafurasee, Baai van Bengale

Tuis

It is usually found in waters less than 90 m deep, on sand and mudflats, and also near rocky coral reefs and seagrass beds. At high tide it moves into shallow lagoons and reef flats.1

Lengte

Wat eet dit?

It eats shrimp, small bony fish, molluscs, crabs and worms. It pins its prey to the seabed with its fins, then crushes it with its plate-like teeth.1

Hoe om dit te herken

Flat, diamond-shaped (rhomboid) body that is dark green with blue spots1
Light white underside1
Very short snout with an angular disc1
Bright yellow eyes1
Long tail, about twice the length of the body, with two venomous spines at its base, one large and one medium in size1

Word dikwels verwar met: It is often confused with the blue-spotted ribbontail ray, which is common in aquaria. The ribbontail has a rounded body, brighter green colouring and more vivid spots. Kuhl's maskray is larger.1

Gifkrag

Steke

Gif kom deur 'n angel uit.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Steek moet deur 'n dokter gesien word. Sterftes is baie skaars.

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

Wat doen dit as dit bang is?

Its bright colouring warns predators of its venomous spines. It buries itself in sand to hide from predators.1

As dit steek

Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand (toets dit met jou eie hand), vir 30 tot 90 minute. Kry mediese hulp, veral vir klipvisse en pylsterte.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

die moeite werd om te weet

Feite

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
