whale in bubble net
Vertical Humpback whale attacks its prey by encircling them in a "bubble net"—a turbulent cylinder of bubbles the whale creates by expelling air through its blowhole as it spirals upward toward the ocean surface. The path of the whale has been traced for clarity by a series of columns of bubbles. The bubble net can be as small as five feet in diameter. Such tight turning is made possible by the hydrodynamic lift generated by the whale’s long pectoral flippers. Patricia J.
