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

Kako ga prepoznati
- Elongated, flattened body with a mouth that points upwards and a lower jaw longer than the upper jaw1
- Large, flat head with the eyes sitting almost on top of it1
- Greenish brown colour with several dark marks on the upper side of the head1
- Yellowish brown flanks with bright blue and yellow broken stripes, plus oblique black stripes along the sides that look tiger-like1
- Venomous spines on the first dorsal fin and on each gill cover1
Otrovna snaga
Oštre bodlje nose otrov. Boli ako ga nagaziš ili zgrabiš.
Što radi njegov otrov kad ugrize ili ubode?
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
Koliko je opasno za ljude?
Opasnost za ljude: OzbiljnoAko te ubodu njegove bodlje, idi liječniku. Smrtni slučajevi su vrlo rijetki.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
Ako te ubodu njegove bodlje
- Stavi ranu u vruću vodu, toliko vruću koliko osoba može podnijeti bez opeklina (provjeri je vlastitom rukom), na 30 do 90 minuta. Potraži liječničku pomoć, osobito kod ribe kamena i raža.
Uvijek prvo nazovi broj za hitne slučajeve (112, 000, 911). Ovo su opće upute za prvu pomoć, a ne liječnički savjet. Osnove prve pomoći
Ostani na sigurnom
- Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
- Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
- Ako te ubodu njezine bodlje: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.
Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice
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
Razbijač mitova
Mit: A weever sting is often thought to be fatal because of the venom itself.
Istina: Reported fatal accidents are widely believed to be caused by secondary infections and sepsis rather than the toxin itself.1
