Since we can't read a whale's mind our answers as to why whales jump is
all speculation based on years of observations and experience. It seems
that at least some jumping, especially in calves, is play/fun.
Sometimes a whale will beach a number of times and then defecate so it
my be caused by indigestion or digestion in some cases. There is breach
feeding techniques for some individual whales, and some researchers think
that breaching might be a form on communication technique using the sound
of landing in some manner, maybe location as in "here I am."
I equate trying to define why a whale jumps to why humans make a fist. We
make a fist in threats, triumph, excitment, play, etc. Whales most likely
do NOT breach for only one reason.
I hope that this helps.
