Kevin Moraga, 15, the victim of a shark attack on Sunday, died after enduring massive blood lost, San José’s Hospital Mexico said through a press release.
A shark bit Moraga while he surfed with friends in Playa Grande, in the northwestern province of Guanacaste at 12:15 p.m. on Sunday.
Moraga was transferred on Wednesday in a coma to the Hospital Mexico in San José, where doctors are better equipped to handle trauma patients. He died Thursday afternoon of a cerebral edema. An edema is caused by a large build-up of fluids in the brain.
Elidio Mendoza, from the Cartagena Red Cross, told The Tico Times that Moraga had a “considerable wound” in his left thigh.

Kevin Moraga, 15, suffered a shark attack while surfing with friends in Playa Grande, in the northwestern province of Guanacaste at 12:15 a.m. on Sunday.
Elidio Mendoza, from the Cartagena Red Cross, said Moraga has “considerable wound” in his left thigh.
“Happily, in spite of the injury, the boy was conscious and vital signs were also good,” Mendoza said. “But obviously he had fainted due to the blood loss.”
The Cartagena Red Cross said they have not attended to any shark attacks in recent years at Playa Grande.
Moraga remains under observation in an intensive care unit at Hospital La Anexión on the Nicoya peninsula in Guanacaste.

A team of researchers encountered a very large bull shark on the Pacific coast of Costa Rica. The shark was more than 13 ft long, which is really big for a bull shark. The largest bull shark ever recorded was only about 11 ft.
The shark was discovered at the mouth of the Rio Sirena, in Corcovado National Park.
The team was able to equip five young sharks with acoustic transmitters that will track their movements (see photo above).
The bull shark, species classified as “near threatened”, is one of the few sharks that can survive in freshwater. I’d hate to run into the new guy in one of those rivers…
