Cynoglossus
Introduction '''''Cynoglossus''''' is a genus of fish in the family Cynoglossidae. Most species are indigenous to the Indo-Pacific region, but there are also a few in warmer parts of the East Atlantic. They are commonly found in shallow waters on a muddy or sandy bottom, including estuaries and a few species are restricted to fresh water. One species ''Cynoglossus sinusarabici'' has invaded the Mediterranean Sea through the Suez Canal from the Red Sea, a process known as Lessepsian or Erythrean migration.
