Bull sharks are apex predators, playing a critical role in maintaining the balance of marine ecosystems.

Carcharhinus leucas, commonly known as the bull shark, is native to warm ocean waters worldwide. It is found in the Atlantic Ocean from Massachusetts to Southern Brazil and from Morocco to Angola, in the Indian Ocean from South Africa to India, and in the Pacific Ocean from Baja California to Peru and from Japan to Australia. They are also found in the Mediterranean Sea.

Bull sharks inhabit shallow, warm waters of coastal areas, often less than 30 meters deep. They are unique among sharks for their ability to live in both saltwater and freshwater and are frequently found in rivers and lakes. The temperature range they prefer is typically between 20°C and 30°C.

Bull sharks are apex predators in their habitats, playing a crucial role in maintaining the health of marine ecosystems by controlling prey populations. They are opportunistic feeders, consuming a diverse diet that includes fish, dolphins, birds, and even other sharks. Their ability to thrive in both marine and freshwater environments allows them to exploit a wide range of food sources.
