On June 26, a rare species of angel shark, known scientifically as Squatina occulta, was accidentally caught in a fishing net near the entrance of Guanabara Bay, Brazil. The shark, measuring about 1.2 meters in length and weighing approximately 15 kilograms, was released alive back into the ocean by a fisherman from the Z-13 Fishing Colony in Copacabana during a field activity for the Raias da Guanabara Project, which monitors such species in the area.

The Squatina occulta is classified as one of the most threatened shark species globally due to its slow growth rate, late sexual maturity, and low reproduction rates, making it highly vulnerable to fishing exploitation and environmental degradation. This incident brings attention to the conservation challenges faced by this species, which can reach lengths of about 1.3 meters and can be found from Southeast Brazil to Argentina.

The return of the angel shark to its natural habitat highlights the importance of conservation efforts in Guanabara Bay, particularly those conducted by local initiatives such as the Raias da Guanabara Project. The classified status of the angel shark as Critically Endangered by ICMBio indicates an urgent need for protective measures to ensure the survival of this rare species in its natural environment.
