Greater weever
The greater weever is a small sea fish that buries itself in shallow sand along the eastern Atlantic coast and in the Mediterranean and Black Seas. Its spines carry a venom that causes intense pain, so it is one of the most dangerous fishes in the Mediterranean for swimmers.1

Lakas ng kamandag
May dalang kamandag ang matatalim na tinik. Masakit kapag naapakan o nahawakan ito.
Ano ang epekto ng kamandag nito?
The venom contains a large protein called Dracotoxin, which can be lethal in high enough doses. It damages cell membranes, and the sting is followed by a short period of tissue changes around the wound. The best-known effect is excruciating pain that begins shortly after the sting and can last from a few hours to days.1
Gaano ito kapanganib sa tao?

Napakabihira ng namamatay.The most common incident happens when a bather steps, jumps or falls onto a buried greater weever in shallow water, especially in summer. Fishermen handling fish caught in nets are also at risk. The pain can reach 10 out of 10 on the numeric rating scale, and some stings have caused pain for months, though this is rare. Reported fatal accidents exist, but these are widely believed to be due to secondary infections and sepsis rather than the toxin itself.1
Kung matusok ka ng mga tinik nito
- Ilubog ang sugat sa mainit na tubig, kasing-init ng kayang tiisin ng tao nang hindi napapaso (subukan muna gamit ang sarili mong kamay), sa loob ng 30 hanggang 90 minuto. Kumuha ng tulong medikal, lalo na para sa stonefish at pagi.
Laging tawagan muna ang numero pang-emergency (112, 000, 911). Ito ay pangkalahatang gabay sa pangunang lunas, hindi payong medikal. Mga batayan ng pangunang lunas
Mag-ingat
- Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
- Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
- Kung matusok ka ng mga tinik nito: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.
Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat

Mga fact
Its venom glands sit in the skin, and the sting works through a groove along each spine that carries the venom into the wound.1
It is classed as one of the most venomous fishes in the Mediterranean.1
The record weight is 1.74 kg, for a specimen caught off La Gomera in the Canary Islands in 2005.1
Its diet changes with size: small mysids are the most common prey for fish under 20 cm, while cephalopods and fish make up a bigger share of the diet in larger fish.1
Myth buster
Mito: A weever sting is often thought to be fatal because of the venom itself.
Totoo: Reported fatal accidents are widely believed to be caused by secondary infections and sepsis rather than the toxin itself.1
