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

It lives in water from shallow depths down to 150 m, mostly over muddy or sandy sea floors. In shallow water it hides in fine sand, where bathers may step on it or fall onto it, especially in summer.1

It is an ambush predator that waits buried in sand during the day, with only its eyes and the tip of its dorsal fin showing. It attacks prey that come close in a swift, sudden movement, mainly small fish, decapods and mysids.1

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

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

1

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

2

It is classed as one of the most venomous fishes in the Mediterranean.1

3

The record weight is 1.74 kg, for a specimen caught off La Gomera in the Canary Islands in 2005.1

4

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

Atosɛm sɛefoɔ

Atosɛm: A weever sting is often thought to be fatal because of the venom itself.

Nokorɛ: Reported fatal accidents are widely believed to be caused by secondary infections and sepsis rather than the toxin itself.1
