In Friday's Weekend cover story, I looked at how the National Aquarium's new $12.5 million Blacktip Reef exhibit pairs predator and prey in the same tank, in a snowglobe version of an Indo-Pacific coral reef ecosystem. Ultimately, the tank will be teeming with tiny fish, a 518-pound green sea turtle and 20 young sharks. But getting each into the exhibit was no easy feat.
After a delay to ensure they were ready to play nice with their new neighbors, the sharks went into the water last week. Surprisingly, it's a lot like how one might introduce a new goldfish into a fishbowl. Then, watch the young sharks -- most under three feet in length -- as they zip around in their new environs.
