A teenager from Spain died after being stung by a poisonous fish while he was snorkeling in the sea near to Playa d’Aro on the Costa Brava.

The parents of the boy did not see him for around 30 minutes, so they raised the alarm.

Authorities recovered his body from the water, he was dead at that time.

An initial post-mortem concluded that he went into an anaphylactic shock, which was caused by the poison of a fish.

The authorities found a small wound in his neck and marks on his face, which are not found when a person drowns to death.

The autopsy pointed to a fish sting being the cause of the boy’s death.

Forensics are still waiting for the toxicology report of the boy.

Footage said to show the attack, which his parents say involved a weever fish.

Weever fish can cause painful swelling, heart attacks, or severe allergic reactions.

The boy is reportedly from Montagut i Oix, around an hour and a half away from where he died.

A spokesperson of the Montagut i Oix council said:

We have no words. Our thoughts are with the family. All our support in these sad times.

The parents of the boy said that their boy found a jellyfish 100 meters from the beach as he was snorkeling.

The boy filmed the fish from a distance before it bit him around the jaw area.
