Sharks and penguins living together at Cal Academy


Six pyjama sharks were released into the Steinhart Aquarium Tuesday morning, joining a colony of African penguins. Biologists say not to worry. The seemingly unlikely housemates co-habitate in the wild along the South African coast.

The pyjama sharks are nocturnal bottom feeders and shy by nature, while the penguins fish in shallow waters during the day.
