The sandbar shark (Carcharhinus plumbeus) is a species of shark of the genus Carcharhinus and of the Carcharhinidae family. It is present more or less in all tropical seas and in the temperate zones of the earth. The color can vary from bluish to burnished gray up to bronze, with a clear or white belly. Generally they are solitary, but we can find them in variable numbers divided by sex. They are active mainly at night, especially at sunrise and sunset. It is often found in waters below the coast with shallow, sandy or muddy bottoms. However, it can swim at depths of over 200 meters. As we know, sharks are at the top of the marine food chain: they are in fact considered real sea scavengers. However, in recent times we have been witnessing a decrease in the species due to indiscriminate fishing by the man who often kills them only to take only their fins. squalo grigio Carcharhinus plumbeus

The cay is about 25 kilometers long and 3 kilometers wide and is the second largest island in the Cannareos Archipelago. Cayo Largo is part of the special municipality of isla de la Juventud. squalo grigio Carcharhinus plumbeus

Cayo Largo is a limestone island, formed over millions of years from the remains of marine organisms, such as the ones that build coral reefs. Living coral reefs form one more attraction for tourists on this island, although coral bleaching has stressed some reef communities in the Carribean. The northern coast of Cayo Largo consists largely of manroves and salt pans. While the water south of the island appears clear enough to reveal the underlying ocean floor, the water on the north side of the island is cloudy. This cloudy water indicates that sediment is washing off the land surface and into the water or is being stirred up from the shallow sea floor.
