Neotrygon kuhlii
O imenu: The 'maskray' part of its name comes from the colour pattern around its eyes. 'Kuhl's' honours Heinrich Kuhl, who discovered it in Java, Indonesia.1

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

Kako jo prepoznaš

  • 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

Pogosto zamenjujejo z: 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

Moč strupa

Piki

Strup pride ven skozi želo.

Kaj naredi njen strup, ko ugrizne ali piči?

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

Kako nevarna je za ljudi?

Nevarnost za ljudi: ResnoPo piku je potreben zdravnik. Smrtni primeri so zelo redki.

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

Kaj naredi, ko se prestraši?

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

Če piči

  • Rano daj v vročo vodo, tako vročo, kot jo poškodovanec prenese, ne da bi se opekel (preizkusi jo s svojo roko), za 30 do 90 minut. Poišči zdravniško pomoč, še posebej pri kamnitih ribah in morskih bičih.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

  • Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
  • Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
  • Če te piči: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

1

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

2

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

3

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

4

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

5

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
