Four Pacific Angel sharks have been born at the Aquarium of the Bay in San Francisco, USA. The pups weighed between 115 and 120 grams at birth and measured 21-24 cm.

“We’re thrilled to have these rare births at Aquarium of the Bay,” said Christina Slager, Director of Husbandry at the Aquarium. “Very little is known about the reproductive behavior of these beautiful sharks, so the information we gather from these pups will be really valuable.”

The Pacific Angel shark (Squatina californica) is found from South Eastern Alaska to the Gulf of California and the San Francisco birth coincides with the pupping season for many local shark species.

The newborns have been moved from the exhibition to more secluded nursery tanks where they will be able to enjoy some peace and quite while being monitored by the husbandry team.

The Aquarium of the Bay is the only nature centre to consistently exhibit, study and care for Pacific Angel Sharks. The Aquarium of the Bay Foundation is currently funding a research project related to Angel sharks, where the collected data on breeding patterns and migration will be made available to government agencies, with the hope of protecting the animals’ habitat.
