Bolinopsis in Terceira Island

3 Bolinopsis in Terceira Island Azores - By boat, close to shore, no wind and sunny day. I don´t know if it matters, but in that day 5 humpack whales were seen more or less 3/4 miles away. Temperatue of the water was probably 18º/19º. We also saw other species but I´m not sure of what was it. Maybe Salpidae. Hope it helps!
