The Orange Sea Perch is distinguished for its strange lifespan, and it is a vital fish to commercial deep-probe fisheries.
The Orange Sea Perch is the biggest recognized deep sea species, with a maximum body length of 30 inches (75 cm), excluding its tail, with a maximum body mass of 15 lbs (7 kg) (15 lbs). The fish is, in fact, has a brilliant, brick-red color body, but this body color will fade after its death.
