Dall’s
Porpoise Phocoenoides dalli
Dall's Porpoise Behaviour
Dall’s porpoise is
often attracted to moving boats to ride the bow wave and
schools of 2 to 12 animals are most common.
Calves are
born in June and July, and mating occurs soon after the
calves are born. Calves stay with their mothers until
the next calf is born. They then gather with other
immature porpoises and adult males in the southern part
of the range. Dall’s porpoises eat deepwater fish and
squid probably at night, and schooling fish such as
herring, anchovy, hake and juvenile rockfish during the
day.
