Harbor Seal

ST. LOUIS (AP) — A third harbor seal that was being moved from Canada to a new exhibit at the Saint Louis Zoo has died.

The zoo says Cri Cri, a 19-year-old seal, died Wednesday. She was being treated at the Indianapolis Zoo after developing problems while in transit from Storybook Gardens, a theme park in London, Ontario.

Two other harbor seals, ages 11 and 12, died on Friday while making the trip. A fourth seal arrived in St. Louis on Saturday and zoo officials say she appears to be healthy.

The seals were to join 11 sea lions at the St. Louis Zoo's Sea Lion Sound exhibit that opens June 30.

An investigation continues into what caused the death of the seals.
