did you know that the scientific name
0:01
for a killer whale is Orsonous orca well
0:04
there's a lot more that you probably
0:06
didn't know so let's get started humans
0:08
can be at risk too although there have
0:10
only been a handful of recorded attacks
0:13
they typically happen when people are in
0:14
the water they don't really attack boats
0:16
though unless they're trying to protect
0:18
their prey the females tend to be
0:20
smaller than the males and even though
0:22
they're called killer whales they're
0:24
actually dolphins that's right they
0:27
belong to the oceanic dolphin family
0:29
despite being the largest member of the
0:31
dolphin family orcas are still
0:33
considered a tooththed whale because
0:34
they have teeth unlike the boline whales
0:37
such as humpbacks and blue whales which
0:40
use a series of plates instead orcas are
0:42
one of the most intelligent creatures in
0:44
the world in some cases they'll
0:47
purposely beach themselves to get at the
0:49
food this was spotted by a researcher
0:51
who was tagging sharks off the coast of
0:53
South Africa orcas are known to kill
0:55
great white sharks just to eat their
0:57
liver and it's believed that they've
0:59
developed this behavior because the
1:01
liver contains a high concentration of
1:03
oil that's rich in nutrients and in
1:06
other cases they'll use rocks to crack
1:08
open the shells of their prey they use
1:10
teamwork to tip over ice flows and knock
1:13
their prey into the water they also have
1:15
the ability to work together to isolate
1:17
a single animal from a pod making it
1:20
easier to capture and eat in one case
1:24
group of orcas surrounded a seal on an
1:25
ice flow and took turns flipping it over
1:28
until it slipped and fell into the water
1:30
then they all ate it together highly
1:32
adorable and social animals who live in
1:34
groups of up to 40 members called pods
1:37
they communicate with each other through
1:38
a variety of clicks whistles and pulses
1:41
that can travel up to 16 m hour each pod
1:45
has its own unique set of calls and even
1:48
though they make a ton of noise
1:49
scientists have developed special
1:51
listening devices to record their sounds
1:54
they're highly intelligent social
1:55
animals who use tools have their own
1:58
unique language and exhibit remarkable
2:00
hunting skills so next time you hear
2:02
someone call an orca a killer whale
2:04
you'll know that it's not just a name
2:07
it's a testament to their amazing
2:08
abilities
2:10
thanks for watching your host Malcolm
2:12
Walker that way they can study how they
2:15
communicate and pass on information to
2:16
each other orcas are known to be deadly
2:19
predators preying on almost any other
2:22
marine mammal including sharks seals
2:25
porpuses dolphins turtles whales and
2:28
even each other in 1972 a killer whale
2:32
named Tikum grabbed a young girl off the
2:35
coast of Canada and held her underwater
2:37
just to be playful that same year
2:40
another killer whale snatched a boy out
2:42
of his kayak near Seattle and in 2003 a
2:46
pot of orcas surrounded a small boat
2:48
near South Africa and pulled it under
2:50
before eating the fish inside even
2:52
though they sometimes go after humans
2:54
we're not on the menu most of the time
2:56
we're more of a side dish on average
2:59
orcas measure between 16 to 20 ft long
3:01
and weigh 4,500 to 6,000 lb there are no
3:06
real predators of adult orcas but baby
3:09
orcas are sometimes eaten by other
3:11
whales sharks seals and even sea lions
3:16
now that's a scary thought baby orcas
3:19
are born with black and white coloring
3:21
but as they mature they develop
3:23
different markings depending on where
3:24
they live the males are typically bigger
3:27
and have a more triangular dorsal fin
3:29
than the females it can grow to be
3:31
almost 7t tall
3:34
now let's talk about something really
3:36
interesting orcas don't really have
3:38
natural enemies but they do have some
3:40
frenemies they sometimes form alliances
3:43
with other marine animals like sea otter
3:46
you heard that right sea otterters will
3:48
ride on the back of orcas to get a free
3:50
ride and help them find food in return
3:53
the orcas get to feast on the sea otter
3:55
prey now here's another fun fact now
3:58
this next fact might surprise you but
3:59
orcas are also known to use tools one of
4:02
the most notorious cases of an orca
4:04
killing a shark happened in 2003 when a
4:07
pot of orcas surrounded a great white
4:09
shark and pulled it down into the depths
4:12
even though orcas are often seen as
4:14
ruthless killers they're actually very
4:16
smart and strategic when it comes to
4:18
hunting as you can see orcas are
4:21
incredibly complex creatures that play a
4:23
vital role in the marine ecosystem
