Miruna

Miruna is a genus of marine fish belonging to the family Sciaenidae, commonly known as croakers or drums. These fish are found in temperate and tropical waters worldwide. The genus Miruna is characterized by a single dorsal fin, two anal spines, and typically a lateral line that extends to the tip of the caudal fin. They are often recognized by the presence of barbels or cirri on their chin.

Species within the Miruna genus are generally medium-sized fish, though some can reach larger sizes. They are demersal, meaning they inhabit the bottom of the sea. Many species are commercially important food fish, valued for their firm, white flesh. Their common names often reflect their habitat, such as "jewfish" or "corvina," though these names can also apply to other fish families.

Miruna species are known for their ability to produce sound, a characteristic shared by many Sciaenidae. They achieve this by vibrating a specialized swim bladder muscle against the swim bladder wall, creating a drumming or croaking noise. This sound is thought to be used for communication, mating, or predator avoidance. Diet varies among species but generally includes small fish, crustaceans, and mollusks.
