Here you can see the ventral pleats on the belly side (allow expansion during feeding).
On of the best believed theories as to why humpbacks show this kind of surface behaviour during feeding season (and when they are not trying to stun their prey) is to knock external parasites off their bodies (also to attract mates during mating season...and maybe just for fun). Here you can actually see some blood on the pectoral flipper, most likely where the banacles were....first time I have ever seen evidence like this....so amazing and THANK YOU Jolinne for pointing it out! Oh....and Arrowhead was NOT hitting the water with his pec he was hitting himself!
Cheers,
