A California sea lion gave birth to a pup unexpectedly in front of a crowd Memorial Day at the New York Aquarium in Coney Island.

The aquarium says that Ariana, the mother, is protective of the pup and is shaping up to be a great mom. It adds that the ability for guests to view the pair may be temporarily limited as the two bond and the pup matures.

“It is unusual for visitors to have the opportunity to witness the birth of an animal at the aquarium,” said interim New York Aquarium Director and WCS Director of City Zoos Craig Piper. “Aquarium staff were on hand to answer questions from the guests, and our keepers and veterinarians continue to closely monitor the pup’s development. This is a special birth that has been a wonderful experience for everyone.”

The aquarium also says the pup is healthy and doing great. It is the mother's first offspring.

When veterinarians can confirm the pup's gender, they will name the young sea lion.
