The blue runner Caranx crysos , also known as the bluestripe jack , Egyptian scad , hardtail jack or hardnose , is a common species of moderately large marine fish classified in the jack family , Carangidae. The blue runner is distributed across the Atlantic Ocean, ranging from Brazil to Canada in the western Atlantic and from Angola to Great Britain including the Mediterranean in the east Atlantic. The blue runner is distinguished from similar species by several morphological features, including the extent of the upper jaw , gill raker count and lateral line scale counts. The species inhabits both inshore and offshore environments, predominantly over reefs , however it is known to congregate around large man made offshore structures such as oil platforms. Juveniles tend to inhabit shallower reef and lagoon waters, before moving to deeper waters as adults. The blue runner is a schooling, predatory fish, predominantly taking fish in inshore environments, as well as various crustaceans and other invertebrates.
