if there's a lesson here
for the calf it's that
:23:04
a dolphin must always
be inventive in finding food
:23:07
for out in the wild
it's no easy task
:23:12
calves are dependent on their mothers
for some three to six years
:23:18
during this period
:23:19
the young dolphin must learn
how to fend for itself
:23:23
like humans, dolphins are not
born with the skills to survive
:23:34
the learning process may start

:23:37
the calf will imitate

:23:40

the calf will follow suit
:23:47

:24:01
dolphins are opportunistic feeders

:24:24
the calf may not be
capable of just yet
:24:40
the buzzing sound is a series
of rapid fire clicks
:24:44
part of a sophisticated sensory
system called echolocation
:24:49
the sound signals
penetrate the sands
:24:51
then echo back, giving a clear
indication of what lies below
