Leaping waves hit the wave ruthless character! Killer whales across the four oceans
Beautiful and huge killer whales are distributed in all
oceans in the world. According to the different ethnic groups, their eating
habits are very different, and the predation strategies of different ethnic
groups are very different. Do you know what the majestic shark fears most? The
answer is the killer whale.
Leap the waves and hit the rugged characters! Killer whales across the four oceans
In movies, TV series, documentaries, and countless marine
aquariums, killer whales are the absolute beauty of the aquatic animal world.
Not only are they scary in appearances, but no matter
children or adults, everyone is deeply fascinated by the black and white body
color of killer whales-look at the small white dots on the black body, it is
simply a giant panda in the water, no wonder there are So many people like it!
Mountain and sickle, distinct dorsal fin
Killer whales have an average body length of 8-9 meters and
weigh 6-9 tons. They are large and muscular; they are the largest aquatic
species in the small-headed dolphin family of toothed whales, also known as
killer whales, killer whales, and orcas; From the North Pole to the South Pole,
it is distributed in all oceans in the world.
Although killer whales all over the world are called killer
whales and their appearance is roughly the same, the huge differences in
habitats (such as polar and tropical) have caused them to differentiate into
many different sub-groups, and these sub-groups are not genetically structured.
There are significant differences in, ecology and living habits.
Some scientists even advocate that killer whales of different
races should be classified into different subspecies or even new species; but
at present, this is just a proposal.
In addition, killer whales are highly dimorphic animals, and
the differences between males and females are mainly reflected in body size and
dorsal fin: adult male killer whales are a bit larger than females. Records
show that the largest male killer whale is 9.75 meters long and weighs 9524 kg;
while the female is 8.53 meters long and weighs 6803 kg.
The dorsal fin of the killer whale is located in the center of the back, flat, narrow and towering, like long spines growing across the branches of thorny plants. Most male dorsal fins can grow up to 1-1.8 meters high, with a solid bottom and sharp top, like a steep mountain, which is highly recognizable and full of tough masculinity.
Killer Whales have Diversified diet, even close relatives can eat well
The killer whales at the top of the marine food chain are keen to hunt all kinds of fish, mammals, marine invertebrates, seabirds and turtles.
Their food types are the most diverse of cetaceans, with different
habitats Ethnic groups have their own unique eating habits, which will be
passed on from generation to generation.
For example, killer whales that live in the Arctic will hunt
walruses, harp seals, ring seals and crested seals for food, and occasionally
besiege large whales such as narwhal and beluga.
The killer whales of Antarctica have a soft spot for leopard
seals, and the two animals have been hostile to each other for a long time.
There, the killer whale even became the only natural enemy of the leopard seal.
The killer whales living in Alaska have surprising food
addictions. Their favorite food is precisely their close relative, the
white-rumped vaquita.
The white-rumped vaquita is a small dolphin that swims very
fast (a little bit bigger than us humans). They are covered with black skin and
have white spots on their abdomen and dorsal fins. If you don’t look at the
size alone, they and The killer whale is almost carved out of a mold.
Imagine if you also have a relative who shines and drools when you see yourself, and wants to swallow you all the time, how tired you have to live?
So here, we express our most concerned condolences to the hard life of the white-rumped porpoise.
In addition, the killer whales living on the northwest coast
of North America also prey on land animals. Moose and other deer animals often
swim across the sea between islands near the coast to find food. When they
enter the water, hum, they enter the range of killer whales.
What horns, hairs, hooves, and tails can make it difficult to
digest. Killer whales don't care about these. Since the cute and attractive
deer came to the door, of course they would eat it quickly.
Thirty-six counts! Dazzling predation strategy
Killer whales are extremely intelligent, and they may be one
of the smartest animals in the sea; this is mainly reflected in their predation
strategy-each group has a set of different predation strategies that are quite
different.
These strategies are complicated and often suspicious, making people guess the beginning but not the end; and the strategies are intertwined and interlocking, and the wonderful things abound.
Watching them hunting is
like watching a live "Thirty-Six Strategies", which is dazzling and
amazed!
Killer whales living in the Arctic will single out small prey such as walruses, harp seals, ring seals, etc.
When facing bowhead whales,
humpback whales, and even huge fin and blue whales, they call Peng Huayou,
using quite clever means to launch the wheel tactics-this is actually the same
as the wolf pack tactics-siege without attacking, frequent harassment, until
the opponent's physical strength is exhausted before launching a general
attack.
When hunting fur seals, killer whales will launch the
strategy of "the reality is the imaginary, and the imaginary is the
real": they will appoint a strong forward with a large dorsal fin to swim
on the water surface to attract the attention of the seal group .
At this time, the other killer whales dived deeper and approached quietly from the left and right sides of the seal group. Hearing only one command (of course, only they can hear their command, it is ultrasound after all), the killer whales on both sides jumped out of the sea, opened their blood basins and opened their mouths to give the seals a lightning strike.
The
seals were frightened. Rong lost her color, so she had no choice but to flee
and plunge into the sea. As for the guys with inflexible legs and poor
reactions, they have become the dead souls under the sharp teeth of killer
whales.
But in fact, the strategy to this step is only a false move. The main purpose of the killer whales that suddenly jumped out is to intimidate the seal group and make them jump into the sea in a panic.
Once in the sea, the
Nature TV will automatically switch the channel and start broadcasting the
killer whale exclusive program.
The fastest swimming speed of the killer whale can reach
55km/h, and the northern seal, the representative of the seals, can only reach
8km/h even if they do their best.
At this time, the big killer whale that previously served as the bait took the lead in attacking, and the killer whales ambushing in deeper waters followed closely behind. So blood, fat, meat, and fur (the fur seals are hairy). All kinds of things are either swallowed in the abdomen, or torn into pieces, just floating in the upper, middle and lower layers of the sea, as if they are showing to the world.
This is the collective cemetery of the sea
dogs. The picture is really too bloody, so I just touched it here.

The killer whale population living in New Zealand mainly
feeds on cartilaginous fish, and its menu includes a variety of ray fish and
sharks. For killer whales, sharks are more than just food, they are also their
competitors, so if they can fill their stomachs and eliminate a guy who will
snatch their food resources, such a cost-effective business will kill two birds
with one stone. Why not?
When attacking large filter-feeding sharks, they basically
use wolf pack tactics to win by number; but if their opponents are similar to
themselves or smaller (the great white sharks, ferret sharks and Pacific
sleeping sharks are all in this category), the tiger The whale will use the
hand-to-hand tactics of "fist and fist": one after another killer
whales swing their tails to increase their speed, and directly slam these
sharks from the side.

After evading the powerful collisions time and time again,
some sharks concussed their brains and fell into a state of fainting after
turning their eyes. Next, the killer whale with its index finger moved
swallowed its saliva and opened its mouth wide to eat and chew.
What are sharks most afraid of? The answer is killer whale
In 1997, cetacean researchers discovered that when killer
whales in the Farallen Islands were hunting great white sharks, they used the
above methods to knock the great white sharks stunned, and then they turned the
shark's whole body in a circle so that its belly was facing up. The great white
shark suffocated and died before tearing its body apart and eating its flesh.
There was a cruel hunt like a revenge ritual.
An interesting digression-for great white sharks, killer
whales may be the most unwilling creatures to see in the vast ocean. They are
afraid of killer whales, scared to the point of incredible.
Picture 15: Retreat, there are killer whales here!
Scientists have done a study in the western waters of
Australia where great white sharks gather. After they played the calls of
killer whales, the great white sharks in the surrounding waters looked like a
group of frightened wild horses, turning their heads and fleeing; for as long
as three hours. During the playing time of, not even one shark appeared in the
sea area.
Today, the calls of killer whales have been proven to have a
strong shark repellent effect. Researchers are using this advantage to transform
the beaches, so that the beaches where tourists gather are protected from
sharks and become safer.
The ruthless role of the ocean hunting ground
Having said that, among the killer whale's predation methods,
the most wonderful thing may be the next trick-"Mantis catches cicadas,
and the oriole is behind."
Killer whales living in many areas have the habit of preying
on birds, and birds such as cormorants and seagulls are regular visitors to
their stomachs. There was a record that killer whales deliberately drove
schools of fish to the surface of the sea, and the seagulls flying in the sky
took a look, oh my god, good fellow! Fish are densely packed! So the seagulls
roared and plunged into the sea, and began to prey on small fish.

At this time, hehe, while showing a smug grin, the killer
whale quickly floated up, swallowing many greedy seagulls in their mouths, and
asked them to settle down in their stomachs and spend the rest of their lives
without thinking. .
The killer whale is a cunning and intelligent animal. In
nature’s hunting grounds and wars against other creatures, they are majestic
and commanding generals, as well as far-sighted and talented staff and
soldiers, and at the same time decisive and unhesitating frontline fighters.
The three advantages converge in one place, no wonder they
can sail across the four oceans and become the most feared and ruthless
characters in the sea.
