Sometimes it's not a good idea to walk barefoot across a beach...

Hidden just beneath the sand in shallow waters, the weever fish is a notorious beach hazard across Europe and North Africa. Most victims don’t even see it before it strikes.

Small, camouflaged and almost invisible, it lies buried with only its venomous dorsal spines exposed. A single, accidental step can trigger intense, burning pain, inflammation and nausea that can last for hours. In rare cases, it too can cause death. 

Like a lot of creatures dead or stranded specimens still pose a threat, so it’s a good idea to wear protective footwear in weever-prone waters, especially on calm, sunny afternoons in the summer, when weevers are most likely to be buried in the sand… waiting for prey.

Some studies suggest encounters with weever fish could become more common as climate change expands their range and alters their behaviour, making it more important than ever to know how to spot

They can be found in the eastern Atlantic Ocean, the North Sea, and the Mediterranean Sea

These pencil-sized predators aren’t out to harm humans: they bury themselves in the sand in the hope that some lunch might swim by. They don’t attack humans (I doubt our feet are particularly tasty to them) but if you don’t see them camouflaged in the sand, it’s very easy to stomp on their dorsal fin and get stung. 

Weever fish stings don’t tend to be fatal (unless the person has an allergy) but they really hurt. If you stomp on a weever fish, you might experience swelling and numbness but the pain will go away with time
