Image Gallery: Sharks Make Home With African Penguins
Shark Meets Penguins
The California Academy of Sciences introduced a group of pyjama sharks to its popular African Penguin exhibit. The two species are natural neighbors off the coast of South Africa.
Surface Feeding
For several months, biologists have been training the sharks to feed at a target location, allowing them to closely monitor each animal's progress.
The pyjama sharks were introduced, two at a time, to the aquarium's African penguin exhibit on July 31, 2012.
Shark Exam
Each animal received a physical exam before being introduced to the exhibit in African Hall.
Shark Cave
Biologists built underwater caves for the shy pyjama sharks, which live with a colony of African penguins at the Academy.
Still Building ...
