Weever

Trachinus vipera

WeeverFish

Weever is a common name for fish of the family Trachinidae, which are known for their venomous spines. These fish are typically found in the sandy or muddy seabeds of the eastern Atlantic Ocean and the Mediterranean Sea. They are notorious for their painful stings, which can cause severe pain and other symptoms in humans.

Description

Weevers are elongated fish with a somewhat flattened body. They have a large head and mouth, with eyes positioned on top of the head. The most distinctive feature of weevers is their venomous spines, which are located on the first dorsal fin and the gill covers. The venom from these spines can cause intense pain, swelling, and in some cases, more severe reactions.

Species

There are several species of weever fish, including:

• Greater weever (Trachinus draco)
• Lesser weever (Echiichthys vipera)
• Starry weever (Trachinus radiatus)

Habitat

Weevers are typically found in shallow coastal waters, often buried in the sand with only their eyes and the top of their head exposed. This behavior makes them difficult to spot and increases the likelihood of accidental stings by humans.

Venom

The venom of weever fish is a protein-based toxin that can cause severe pain, swelling, and redness at the site of the sting. In some cases, it can also cause systemic symptoms such as nausea, vomiting, and difficulty breathing. The pain from a weever sting can last for several hours and may require medical treatment.

First Aid

Immediate first aid for a weever sting includes immersing the affected area in hot water, as the heat can help to denature the protein-based venom. Pain relief and medical attention may be necessary, especially if symptoms are severe.

Prevention

To avoid weever stings, beachgoers and swimmers should be cautious when walking in shallow waters, especially in areas known to be inhabited by weever fish. Wearing protective footwear can also help to reduce the risk of stings.
