Their colouring may seem drab and unimpressive, camouflaging them will with the seafloor - until it spreads its brilliant blue pectoral fins, from where it draws its name. Just in front of these fins, you might notice that it appears to have a set of little “legs” that helps it creep along. These are not actually legs, they are modified rays of its fins, which the gurnards use to stir up the sand to find prey – small crustaceans. Gurnard's bodies are long and compact, with armoured, bone-plated heads.

Threats:
Some of the threats faced by the bluefin gurnard are pollution, overfishing, climate change etc.
