Dolphins

:24:01

dolphins are opportunistic feeders

:24:03

and the young must learn
many extremely difficult

:24:07

and creative
hunting techniques

:24:21

the mother is using
sound in a way

: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

:25:05

it's like x-ray vision

:25:06

capable of seeing through
almost any porous medium

:25:21

dolphin calves can create
sounds shortly after birth

:25:25

mostly whistles
used for communication

:25:29

the clicks required for echolocation
may take months to develop

:25:35

like most intelligent
predators

:25:37

dolphins learn to hunt
by making a game out of it

:25:52

this trunkfish is
not part of their diet

:25:55

but for the young dolphins

:25:57

it's a target to practice on
