Distribution sources

Identification

Compare Echiichthys vipera with greater weever: the absence of lateral streaks and of spines above the eyes matters more than an assumed small size. Do not raise the dorsal fin by hand to check.

Upturned mouth, high-set eyes and black first dorsal fin; no spines above the eyes.

Habitat

It may remain buried very close to shore; an inconspicuous fish does not mean there is no risk of contact.

Sandy or fine-gravel bottoms, including very close to shore.

Diet

Small coastal fish and crustaceans.

Behaviour

Ambush hunting explains why it can be difficult to see before contact. These observations do not justify specifically targeting it with rod and line.

It ambushes prey while partly buried in sand.

Indicative biological size

Average size of 6–11 cm according to Guillaume Fourrier.

Fishing context and precautions

Fourrier describes incidental catches from a boat at slack water, on a string of feathers worked close to the sandy bottom, sometimes with a small terminal jig. Prepare to unhook the fish without contact with its venomous spines.

The Chtipecheur log also documents incidental summer surfcasting catches on the Dunkirk coast; this local corroboration does not establish a targeted rig.

A distinctive feature

Venom remains active after death: do not handle it with bare hands.
