Discover fishes of the family of Carcharhinidae

Carcharhinus falciformis, known as the silky shark, is widely distributed in tropical and subtropical seas. However, this species is threatened due to overfishing, and is classified as vulnerable by the IUCN. Recognizable by its elongated and slender body, gray back, and white belly, this fast and aggressive predator feeds on fish, mollusks, and crustaceans.

The bull shark is listed in most tropical and subtropical seas. It is feared due to its propensity to attack humans, being responsible for most recorded fatal attacks to date. This active predator primarily hunts in murky waters. It is capable of swimming long distances and adapts to changes in salinity, frequenting estuaries, coves along the coasts, and waters with high turbidity.

The blacktip reef shark is viviparous and gestation lasts about a year. The litter varies from 2 to 4 juveniles, measuring about 40 centimeters. After giving birth, the female abandons it juveniles. If disturbed, this small sized shark, may attack. It gets into the Mediterranean more and more often via the Suez Canal.

The tiger shark is the third largest shark in the world. It is recognizable by its distinctive stripes along its sides, and by its short, flat snout. Tiger sharks are opportunistic hunters, known for their "bite-and-see" exploratory behavior to assess the nutritional value of their prey. These sharks generally prefer shallow waters, but can sometimes be found at greater depths.

The blue shark, also known as the "blue skin shark," is a pelagic predator found in temperate and tropical marine waters, with occasional sightings near the coast. Its wide distribution, however, is threatened by overfishing. Recognizable by its blue back and white belly, this sleek-bodied shark mainly feeds on small fish, mollusks, cephalopods, and sometimes birds.

The scalloped hammerhead shark, a semi-oceanic hammerhead, is found in tropical and temperate waters worldwide. This species is easily recognizable by its curved flat head and black tips on the pectoral fins. These sharks feed on fish, cephalopods, and crustaceans, taking advantage of their flat head to make tight turns while hunting. Although potentially dangerous and aggressive towards intruders, attacks on humans are rare. Conversely, despite its wide distribution, this species is threatened with extinction.
