No, The Mahi-mahi (in Hawaiian), Coryphaena hippurus, also known as common dolphin-fish, dorado maverikos, or lampuki (in Maltese) are surface-dwelling ray-finned fish found in off-shore tropical and subtropical waters worldwide.

It is called a dolphin fish but it is not a dolphin it is a fish with red fins.

The name "mahi-mahi" ("strong-strong" in Hawaiian), particularly used on restaurant menus, has been adopted in recent years to avoid confusing these fish with dolphins, which are mammals.
