NEWBORN 02 03 SDOP 42 The day started promisingly 02 Freediving is the with three sightings and an only practical way to underwater encounter to approach sperm whales within about 14 metres. From 03 Nine hours a day in a small boat gets a small boat like ours, it was extremely tiresome not possible to see whales 04 Soon the calf could from the surface. Therefore, swim independently for short distances we worked with two vigias 05 The mother’s da baleia who watch out massive head got for whales from hillside bigger and bigger observation towers, remnants from commercial whaling days. The boat’s radio suddenly crackled, and from the driver’s reaction I could tell it was a good message. A group of about six animals had been spotted about one nautical mile to the south. Courtesy of twin 150-horsepower motors, we reached the spot quickly and there was our prize. The pod was swimming in circles very slowly, which was decidedly unusual behaviour. We cut the motors to avoid scaring them away, and kept to a safe distance of about 150 metres. With a last look at the pod’s position, I gently slid into the water. For the first 80 metres I swam as fast as possible, scanning the blue to get a glimpse of the animals, but there was nothing but a big murky cloud. I soon realised that the cloud was blood, which appeared greenish because of the loss of red light underwater. This explained the pod’s strange behaviour. I thought they must be watching over a wounded member. Female sperm whales are famously social. They form networks with their young and live in groups of 15 to 20 animals. Sexually mature males leave the pod and form associations with older males but travel alone. I assumed, correctly as it turned out, that this was a pod of females. As the whales’ communication sounds intensified and I got nearer, I could discern the group about 30 metres in front of me, huddled just below the surface. But with the sun directly in front of me it was difficult to see exactly what was going on. I descended to about 15 metres to pass carefully beneath them. My descent revealed that my initial assessment was wrong. There was no wounded animal; it was a mother giving birth. The placenta and pieces of skin were floating in the water around the calf, which had left the womb only seconds earlier.
