Two more cetaceans

Okay, here are the two other species of whales we saw this weekend.  These first two pictures are of one individual — they show the dorsal fin and then the flukes:

 

 

Humpback Whales (Megaptera novaeangliae) are known for their "knobby" dorsal fins and their large flukes with a deep central notch and serrated trailing edge.  

We saw several Humpback Whales on Saturday.  The photos below are of a different individual.  They show the fin and back; the flukes from above; and a side shot showing the flukes from below, in case anyone wants to try to identify this individual whale by the color patterning:

 

 

 

And the fourth species of cetacean we saw on 30 July 2016?

 

I think this is a Common Minke Whale (Balaenoptera acutirostrata scammoni).  It surfaced while we were watching the Blue Whales in the morning, and we only had this one view.  The overall size (relatively small), the dark color, the shape of the dorsal fin, and the behavior made me think "minke."   

Minkes only get to about 6.5-8 meters (21-28 feet) long.  In comparison, humpbacks reach lengths of 11-17 meters (36-55 feet).
