Jimmy Sukat, the dolphin’s Indonesian trainer, said Hindri was showing signs of fatigue and didn’t want to perform in the morning.

Around 3 pm, the tail of a baby dolphin was spotted coming out of Hindri and by 6 pm the calf was fully born, he said, adding that dolphins are usually pregnant for 13 months before giving birth.

As there are no veterinarians with dolphin expertise in Vietnam, the deputy director of Suoi Tien Tourist Area, Doan Minh Tuan, said he will invite experts from Indonesia to examine and care for Hindri and her baby.

Hindri is one of four performing dolphins imported from Indonesia to Suoi Tien. The animals began performing in January 2009.

The tourist area is situated 19km to the northeast of Ho Chi Minh City on the Hanoi Highway where visitors can enjoy natural landscapes including streams, woods and aquariums with hundreds of species of fish and rare animals.
