A marine biologist was seriously injured after being attacked by a shark while working off the coast of Costa Rica. The man involved in the attack has been identified as 48-year-old Mauricio Hoyos, who works with the One Ocean Worldwide Coalition. Hoyos sustained injuries to his head, face, and arms due to the attack.

Costa Rica’s Fire Department reported that Mauricio Hoyos was attacked by a shark on Saturday, September 27, while conducting scientific research on Coconut Island. The renowned shark scientist encountered a Galapagos shark during his work on the island, as part of the One Ocean Worldwide Coalition. Luis Fernández, a physician with the Fire Department, explained that Hoyos was tagging shark species for monitoring when he was bitten on the head by a 4-meter shark with an enormous bite force.

It took 36 hours for rescue crews to transport Hoyos from the remote island, located about 340 miles off the coast, to a local hospital. When he arrived, Hoyos was in stable but serious condition, as reported by Mexican broadcaster Noticieros Televisa. The Costa Rica Fire Department has not yet responded to requests for comment from PEOPLE.
Members of the For The Oceans Foundation expressed gratitude towards Hoyos’ rescuers for their quick response and heroic efforts in assisting him. Alex Antoniou, Executive Director of Fins Attached, described the incident as extremely rare and praised Hoyos as an extraordinary scientist dedicated to shark conservation.
Furthermore, the For The Oceans Foundation acknowledged Dr. Hoyos’ leadership in ongoing research focused on shark conservation and oceans protection. Despite the challenging circumstances, the coalition remains committed to their important work, inspired by Dr. Hoyos’ dedication and resilience.
Incidents of shark attacks on marine biologists are rare but can have serious consequences, highlighting the risks faced by those working in the field. The incident serves as a reminder of the dangers faced by researchers and conservationists as they carry out vital work in understanding and protecting marine ecosystems.
The community surrounding the Coconut Island has shown solidarity and support for Hoyos during this difficult time. The incident underscores the importance of continued research and conservation efforts to ensure the safety of those working to protect our oceans and marine life.
In conclusion, Mauricio Hoyos’ experience highlights the bravery and dedication of marine biologists who work tirelessly to study and conserve our oceans. The industry will continue to support and recognise the valuable contributions of researchers like Hoyos, while striving to enhance safety measures in shark-infested waters.
