North Atlantic right whales, which give birth off the coast of Georgia, the Carolinas and Florida each winter, had their most successful calving season in more than 15 years. There are only about 380 right whales left, so every new baby is considered critical to keeping the species from going extinct.

Scientists spotted 23 right whale calves swimming with their moms this past calving season, which runs from November to April. It’s the most new calves since 2009. The number has researchers “cautiously optimistic,” said Amy Warren, scientific program officer at the New England Aquarium.

However, she said calving is only part of the whales’ story.
