Order level detail.
A large and highly diverse group of modern bony fishes many of which have a generalized perch like body form. Most have pelvic fins with one spine and 5 rays and the maxillary bone is excluded from the gape of the mouth. Interrelationships of the group are poorly understood and continue to be studied. They inhabit almost all aquatic habitats from high-altitude strams to the deep sea, although most are marine.

Family level detail.
Powerful streamlined fishes with two dorsal fins that fold into grooves, deeply forked or lunate tails and a series of dorsal and anal finlets before the narrow tail base. They are fast-swimming open-water predators and are extremely commercially and recreationally important.
