Sturgeons have bony plates and thick sucking lips but no teeth. They live in rivers and coastal waters around the world, including the Fraser River, near New York, Alaska, Russia, and China. Sturgeons eat shellfish, worms, crabs, snails, small fish and insects. They are endangered due to overfishing and pollution reducing their populations. People fish and sell sturgeons illegally on the black market. Conservation efforts are needed to protect sturgeons and stop overfishing.
