In a rare event, a school of over a hundred nurse sharks was filmed crossing the waters of San Matías Gulf in Río Negro, Argentina, marking a significant moment in the observation of this species in the region. The nurse shark, typically found in the southern Atlantic, usually inhabits deeper waters, making this sighting particularly valuable for researchers as it provides insights into the current behaviors of the species. The footage was captured by drone pilot Maximiliano Facundo Cartes Salas, whose documentation of the event has garnered considerable attention due to its rarity.

The nurse shark, which can grow between 2.5 to 3 meters in length and weigh between 80 to 100 kilograms, is commonly found in southern Atlantic waters but often remains in deeper locales. This observation could suggest shifts in their habitat or habits, inviting further ecological study. Local biologists have emphasized the importance of documenting such occurrences, as they may reflect broader environmental changes or disruptions in their regular patterns.

The incident not only highlights the biodiversity of the San Matías Gulf region but also raises awareness about the species and the ecological significance of its presence in shallower waters. As such sightings become more notable, they could lead to increased conservation efforts and further research into the health of marine ecosystems in Argentina and beyond.
