Whales Team Up in Amazing Bubble-Net Hunt | National Geographic

well we’re spending our morning watching
one of the most exciting biological
phenomenon any place to be seen the
bubble net feeding behavior of humpback
whales it is exciting in the extreme you
got a group of animals all traveling
together they know where the prey is
before they dive or have some sense of
it single animal breaks off from the
group dive down it starts spiraling
upwards and blowing that blowing air out
of its blowhole which rise up and
creates that cylinder of bubbles now
almost certainly they’re doing that
above where the fish are located because
of the constraints on bubbles traveling
to the surface it can’t be that deep
when they deploy it and the fish tend to
be located below that depth so the
remaining animals I have to force that
prey up into that pre-existing bubble
net has already been deployed and so
what seems that happen is one individual
will vocalize in an effort to drive the
fish up towards the surface while the
remaining animals seem to flank that
group of herring that school of herring
tain them corral them as they’re being
pushed into the existing bubble net and
then once that happens just before they
break the surface when it occurs they
are the whales actually come from the
outside of the bubble that convene in
the center to do that final push to the
surface
