Panga is the common South African name for Pterogymnus laniarius, a small, ocean-dwelling fish, native to the southeast Atlantic Ocean and southwest Indian Ocean. Alternatively called "torpedo scads", they're cold-blooded with white flesh. Their scales are generally pink in colour with whitish underbelly and blue-green stripes running laterally along their sides.
Over the course of its life, a panga will undergo periodic sex-changes with as much as thirty percent of the population being hermaphroditic at a time. Despite the presence of both sex organs, it is thought unlikely that both are simultaneously active. Panga are slow to reach sexual maturity, with a minimum population doubling time of 4.5–14 years.
In additional countries, the name panga might refer to a different species. In Indonesia, it refers to Megalaspis cordyla, in Spain, France, the Netherlands and Poland it refers to Pangasius hypophthalmus, and in Kenya it refers to Trichiurus lepturus.
