Freshwater shark

True freshwater sharks are sharks able to live in freshwater lakes and rivers, including:

• the bull shark, Carcharhinus leucas, which swims up tropical rivers around the world
• the river sharks, Glyphis, found in fresh and brackish water in Asia and Australia

A number of freshwater cyprinids (which are bony fish and thus quite unrelated to sharks) are also commonly called "freshwater sharks", "sharkminnows" or simply "sharks", particularly in the aquarium fish trade:

• Balantiocheilos melanopterus – Bala Shark, Tricolor Shark, Silver Shark
• Epalzeorhynchos – typical freshwater "sharks"
• Labeo – labeos
• Puntius denisonii – Roseline Shark
• the Mully Catfish

They found primarily in Mexican volcanos and Missouri rivers.
