Story summary

A dolphin named Echo from Marineland in Niagara Falls, Ontario, died at Oceanografic Valencia in Spain on Wednesday. Echo, a blind Black Sea bottlenose dolphin in her late 20s, had trouble swallowing and respiratory issues. She was one of four dolphins and two belugas transferred to Oceanografic on August 26 from the closed Marineland park. This is the fifth animal death since 30 belugas and 4 dolphins were relocated over the summer; four belugas also died at Shedd Aquarium in Chicago. Marineland had shut down due to financial issues and could no longer care for its whales. Oceanografic, where Echo was transferred, increased monitoring but her condition deteriorated rapidly despite efforts by veterinary teams.
