Sea Robins Fish Species are members of the Triglidae family, which has gurnard fish (sea robin) as their emblem. Gurnard fish is known for its unique physical features. The orange ventral surface of the West Atlantic and large pectoral fins, which open when swimming, close like the wings of an airplane to create a larger wing surface area similar to it.
In the Triglidae family, there are three genera and about twenty species. They live in temperate waters of the Atlantic Ocean and the Pacific Ocean, usually in deep oceanic trenches. The fish found in the Atlantic are called sea robins and those found in the Pacific are called gurnard; a family of bottom-feeding scorpaeniform fish. They get their name (sea robin) from the orange ventral surface of the species in the Western Atlantic (Prionotus carolinus) and from large pectoral fins which resemble a bird’s wings.
Sea robins have several distinctive features, including their drumming muscles. These muscles can be found in the abdomen, and when the fish is caught against its swim bladder, they beat to produce a sound similar to that of a frog.

Body Structure of Sea Robins Fish Species
Robinseas are fish with armored heads and elongated bodies. Their front fins are wings, which they use to move along the bottom of the sea and to hunt for food. They live below 20 meters. Their touching wings are the size of wings, with a few rays underneath each forming a separate feller. The body is typically dark red, but the fins are translucent pink. It has a covering of thick armor plates and spines over its entire body.
Sea robins are remarkable in both looks and behavior. These creatures have fierce eyes and a pointy nose, but they only grow to be about 11cm long. Their bodies are flat, with the head being flatter than the body. The armor on their heads has a long point on it that resembles a fin. The snout develops both broad and long protrusions that end in sharp points.
The sea robin has three “walking rays” on each side of its body. These are derived from the supportive structures in the pectoral fins, called fin-rays. The walking rays in sea robins have been shown to be used for locomotion and prey detection on the seafloor via chemoreception, a method of detecting chemical substances. The most prevalent amino acids in marine invertebrates are detected by this chemoreception, which is highly sensitive.
Habitat and Diets
Sea robins are very common. All members of the group live in tropical waters, but most inhabit the Pacific. The latest species to be discovered was found off the coast of Costa Rica and lives at a depth of 110 meters or more. Its diet consists primarily of annelid worms, small crustaceans, and small fish.
Uses
Gurnard is a member of the sea robin family, Triglidae. They have firm white flesh that holds together well in cooking, making them well-suited to soups and stews. The French especially enjoy Gurnard as a dish called “bouillabaisse,” which is made with tomatoes, onions, garlic, and saffron. They can also be used as bait.
