This video was taken recently in Maui on my first ever whale watch. The assistant on the boat put his special iphone in the water and took this video of a mom and her calf along with their male escort. Each mom and calf have a male escort who protects them. This male is not the father of the baby, but a male who hopes to get with the mom after her calf leaves. You can hear the male singing - only males sing. It's an unbelievably good capture.
