15.10.2016 – Salted herring and Sperm whale spectacle

19.10.2016 – Vertical Sperm Whales
October 27, 2016
Today we had on both trips whales. During the morning we saw shy Blainville’s Beaked whales, which showed up a bit closer to Ribeira Brava as Stenella.
During the afternoon we had a short encounter with a shark, we just could say “Hi”, before we drove on. A little while later we were able to observe two Tropical whales, mother and calf. Very clearly we could follow their direction to swim by following their fluke prints. When the whale moves his fluke he also moves tones of water, which changes the water structure on surface. So fluke prints are not a substance, they are a hydraulic action formed by water turbulences. It looks like a mirror, very smooth. A ring like wall of water blocks waves from entering.
