Rare footage and audio newly released by ProjectCETI reveal an entire sperm whale family (mothers, sisters and even non-relatives) working together for hours to help deliver and lift a newborn calf off the coast of Dominica. #NatGeoExplorers DavidFGruber, Founder and Lead of Project CETI, and Biology Lead ShaneGero were part of the team on the water to witness this moment firsthand. Their observations, now published in two new peer-reviewed studies in ScienceMagazine and NaturePortfolio's Scientific Reports, suggest these cooperative family bonds have been anchored in the deep for more than 36 million years.
