ST. LOUIS, MO (KTVI) – We now know what caused three seals on their way to join the Saint Louis Zoo to die in transit.   Zoo officials say the seals died due to multiple factors, but mainly exertional myopathy.

Three harbor seals died from the muscle disease while they were being transport from the Storybook Gardens theme park in London, Ontario.  Severe cases of myopathy are characterized by stiffness and acute renal failure and may develop under stress.

Zoo officials say the harbor seals were not used to being in a transit situation.  The surviving seal has been taken out of quarantine at the zoo and has adapted to her surroundings.
