Shark near the beach, the alarm goes off but it was only a blue shark.What's the difference?

Moments of panic on the beach because of a shark?No, it was just a harmless blue shark

ROME - Moments of fear today on the beach of Marinella di Sarzana, in the province of La Spezia, when not far from the shore the fin of a shark at least one and a half meters long, probably a blue shark, was spotted at the edge of the water.The news was released by the Rights Desk.Although the species did not represent any danger to humans, the beach lifeguard adopted precautionary measures for the safety of bathers and requested the intervention of the Port Authority of Foce del Magra.The Harbor Office staff intervened promptly, identifying the shark among the cliffs in front of the establishment.After a short period of confusion due to the rough sea and the presence of boats, the shark has left the area, allowing swimmers to resume their activities without further worries.
“Sharks often run away from humans - explains Diana D'Agata, veterinary surgeon in the United Kingdom - but our unexpected action can lead to their reaction with a bite”.Giovanni D'Agata, president of the Rights Desk, points out that "with a ratio of over one hundred million sharks killed by humans compared to four humans killed by sharks every year, they are always the first to suffer the worst consequences.But the presence of a specimen near the Italian coast is still a thrilling thought“.

DIFFERENCE BETWEEN SHARK AND BLUE BLUE

But what is the difference between the two specimens, the shark and the blue shark? First of all it must be said that they are both sharks.In fact, the blue shark is a shark belonging to the family Carcharhinidae characterized by a slender body, elongated and narrow pectoral fins while the others are short and pointed, it is also known as blue shark for the blue of the lateral-dorsal area, light, whitish the ventral one, and its scientific name is Prionax glauca.The blue shark is a large predator, males can reach 2.82 meters and females also the 3.3 meters.They mainly eat blue fish and squid and compared to some similar ones, blue sharks are not dangerous, but they only attack if frightened.According to what experts say, the presence of this predator is therefore not dangerous for humans:the blue shark tends to follow boats but does not recognize swimmers as potential prey.To be honest, even the feared great white sharks have no interest in humans because we are not part of their diet.
