Marine biologist Andrew Nosell, professor of environmental and oceanography at the University of San Diego, recorded with his drone swimming with dozens of leopard sharks on the beach in La Jolla, San Diego, USA. )
Although they may seem scary to many, they can reach 1.5 meters in length, he explains, and these animals are harmless to humans, so they were seen swimming quietly with bathers in San Diego. “[Esses tubarões] They are, for the most part, 97%, mature pregnant women.

The expert has been studying these animals specifically since 2007 and they are common on the San Diego beach between August and September, and can be seen during the summer and fall months (June to December).
Sharks were recorded during a daily survey by a drone last Thursday (12) and quickly attracted attention because the animals were so close to the sand on the beach, near “knee height”. “In our sound surveillance research, these sharks exhibit annual biopathology, i.e.‘ home lover ’: they return to this place every year,” he explained.
According to him, at night, the animals search for food and scatter on food based on small fish commonly used as bait, squid, octopus, crab and crabs.
Today, they represent the economic potential of San Diego and the California coast. “These delicate sharks feed the burgeoning local ecotourism industry, which watches snorkeling and kayaking tours,” he concludes.
