On February 16th, Angolan angler Sergio Reis reeled in an impressive Atlantic Blue Marlin, weighing in at a massive 497 kg (1095 lb 11 oz).
The crew fishing out of Lobito, a port city in Angola, took their huge haul back to get processed and upon cutting the monster open they found something unexpected.
Apparently, people watching on as the belly of the 497 kg blue marlin was cut open were shocked to find the remains of a sailfish fall out.
