The Samson fish, Seriola hippos, a jack of the genus Seriola, is found in the Indo-Pacific Oceans including Australia and straggling to eastern Northland in New Zealand. Its length is between 31.5 and 59.05 in (80 and 150 cm).
The Samson fish has a very low spiny first dorsal fin with no gap between it and the second dorsal fin, which has a high pointed anterior part mirrored in the anal fin.
These fast swimming pelagic fish have similar habits to the kingfish. They are dark blue-green above and silver white below with golden yellow flanks and fins.
