The Humpbacks were in a mellow mood for Tuesday’s Mid-Morning Cruise. Throughout the course of the trip, we got to see spouts, dorsal fins and flukes from 8 different adult Humpbacks. All of these whales were in pairs and while we got to see some interaction within these pods, we didn’t witness any interactions between the pods.
Highlights from the trip included watching 2 different pods of two rolling around each other on the surface and getting to see too many fluke dives to count.
We also got to see a pair of Humpbacks dive at our bow…by the time they resurfaced they were well behind our boat, so we know they swam beneath us. Oh, and when we deployed the hydrophone we heard some very interesting “whoop-WHOOP-whoop” sounds.

Ocean Sports Whale Fact of the Day: Humpbacks produce sounds in frequencies ranging from 10 hz to 24 khz. A healthy young adult human can generally hear sounds in frequencies between the ranges of 20 hz to 20 khz which means that we’re not hearing everything the whales are singing.
