The sighting of a blue shark (Prionace glauca) near the Punta Marqués Protected Area in Rada Tilly (Chubut) has generated great interest among photographers and nature lovers.
Documented by photographer Diego Cabanas, this event highlights the presence of a rare oceanic species in coastal waters.
A team photographic record
The event was captured on Friday, April 11, when the shark was swimming close to the surface.
Cabanas emphasized the teamwork with Alberto Loizaga and Patricio Larrea, reserve staff, to achieve the record. “Without that collective effort, this moment would not have been possible”, he pointed out.
What does the presence of the blue shark mean?
The blue shark is a migratory species from the South Atlantic. Although it is not common to see it near the coast, it occasionally approaches following schools of fish. Its presence does not pose a danger, as it is a elusive animal that avoids contact with humans.
The most relevant aspect is its ecological role, as it regulates marine populations and contributes to the balance of the ecosystem. Spotting it in these waters is a privilege, not a cause for alarm.
Knowledge and conservation
Cabanas stressed the importance of overcoming fear and approaching scientific knowledge. “Knowing is the first step to conserving. Sharing these records not only raises awareness, but also adds scientific value”, he stated.
The blue shark is among the most abundant and widely distributed elasmobranchs. Its high reproductive rate compared to other oceanic sharks and its rapid growth make it more resilient to exploitation than other shark species.
These types of sightings reinforce the need to protect marine ecosystems and understand the importance of key species like the blue shark in ocean biodiversity.
