Killer Whale Report
Killer whales are Carnivores which means it only eats meat. Killer
Whales eat fish, squid, sharks, seals sea lions walruses, penguins,
turtles, octopi and gulls. They even hunt bigger whales as big as they
are. The killer whale is a very powerful predator. The killer whale has
been known for killing a young blue whale and other bigger whales.
They have 10 or 13 pairs of a big interlocking conical, enameled teeth
distributed that is in both the upper and lower jaw. The total of pairs is
20 and 26 pairs. So the orca has 40 and 52 teeth. A killer whale teeth
curve inwards and backwards. This helps the killer whale catch their
prey. Their teeth is about 3 inches (7.6cm) long and about 1 inch in
diameter. A killer whale can eat about 551 pounds (250kg) of food a
day. They are also being found in the cold coastal waters. They can
also be soon in the Polar Regions by the equator. They can be seen
around the world. They have a long population in the northern pacific
basin, coastal areas of Washington State, Johnstone strait and in
California. There are a large number of killer whales near Norway,
and in the coastal waters of Argentina regions. Orcas live in the
waters that ranging from tropical to Arctic. They can also be found in
deeper waters. They are found in all the world’s oceans and some
parts of the sea. Sometimes orcas enter estuaries, but they do not go
far from the sea. They can be found in the Arctic and Antarctic
oceans. They can be found worldwide. The killer whale is a high
intelligent animal. The killer whale is in the dolphin family it is the
world’s largest dolphin. It can grow about 8,000-12,000 pounds.
(3.600-5.400kg). Males are bigger than females. The orcas is called
the killer whale because they are the top predator in the ocean and
very successful hunters. They can be seen in most seas like the
Mediterranean and the Arabian seas. The killer whale is the second-
most widely distributed mammal after the humans. Killer Whale can
swim about 30 miles an hour but they can travel about 26mph for
periods of time. A killer whale can also go for 50 miles without
stopping. There are three different types of killer whales in the world
which are the resident orcas,” they eat fish and squid. The transient
orca they eat marine mammals. There is also the offshore orca they

2. eat fish, sharks and sea turtles. Male killer Whales can grow about 8
meters in a length. Female Killer whales can grow about 7 meters in
a length. A killer whale can eat about 200kg of food every day. Which
also includes over 20 different species? Of marine mammal and even
more than 30 different species of big fish. Killer whales in captivity do
not live longer they live about 25 years. They do live longer in the
wild. Male Killer Whales can even grow about 8 to 9m and females
can also grow about 7-8m. Male Killer Whales can live about 50 and
60 years and females live about 90 years. Killer Whales had never
killed a human in the water. Killer Whales use a special skill to catch
their prey it is called “Scan-hopping”. They use this to catch larger
prey on the shore. The orca is the fastest member in the dolphin
family. It can go for the speeds of 50km 1 hour. When they swim
normal it can move about 10-15km 1 hour. They are very good
swimmers. They can swim about 30 mph (48km) to catch their prey.
Unlike their dolphin cousin’s killer whales are very extreme vocal
animals and communicate between each other using clicks and
whistles in process this is called echolocation. Killer Whales use their
vocals and noisy sounds when they are hunting. Killer whales are
clam and quiet when they are resting. A killer whale can dive about
100feet (30m) to allow them to hunt. Orca vocalizations include clicks
for echolocation this also means for whistles, and scream-like pulses.
Those are use for communicate with other orcas, mating and for
locating prey. A Male Killer Whales average is 19 to 22 feet (6 to 7
meters) in a length. Female’s average is 16 to 19 feet (5 to 6 meters)
long. Some people call the killer whale the wolves of the sea because
they kind of act like wolves. Because they life in a group like wolves
do. Killer Whales live in a group called a pod. A pod can hold 6 and
40 whales. There are approximately 30 mixed sex individuals, some
pods have 150 orcas. Killer Whales are very social animals. Their
bonds are between the members of orca pods are strong and that
last all of their lives. Pods hunt together in a very sophisticate
manner, attacking larger prey and they will share their meal with the
rest of the members. All the members of the pod protect the young.
They also protect the sick and injured orcas. Also have another way
to look for their prey it is called spyhopping this is when the killer
whale pokes its head out of the water to look for prey. When a killer
whale leaps out of the water means it is telling how the animal is
feeling like sad, happy are mad. Female Killer whales give birth to 3
and 10 years. After a 17 month of pregnancy. Females give birth to

3. one baby killer whale like about 5 years. Their gestation period is
about 18 months long. On the baby killer whales skin have a yellow
tint parts on their baby orca’s body. The white parts on the baby will
fade when it gets older. Mothers will look after the calves the first few
weeks of their lives. Female orcas will not reach sexual maturity until
they are about 15 years old calves will drink milk from about a year
until the calf will start to eat solid food. Orcas will begin to mate about
in the early spring but they mostly mate in the winter that is near the
surface and in warmer waters. A female can reach maturity at 6 to 10
years and males are 12 to 16 years old. Some babies gestation
periods are about 16-17 months. A calf is born with it’s tail out first
and that is near the shore, usually between October and in Match. A
new born calf can swim about 10 seconds for the calves first breath.
They usually have to swim near the surface. It will get help from the
mother’s flippers. A new born calf can weight about 400 pounds
(180kg). A new born calf can grow about 6,5-8feet (2-2m). The calf
will stay with its mother about a year or even longer. A mother having
twin babies is extremely rare. A average for a female killer whale is
one birth for every ten years. Some females may give birth to three
and five years. The killer whale is currently endangered because of
habitat loss and people are hurting them. Pollution and contamination
will make orcas to a lot of susceptible to disease and likely cause
reproductive difficulties. They are also in trouble from reduction in
food supply in some areas. They can also be in trouble from
fishermen nets and boats. As the amount of food is reduced they may
have to move it. Some people will kill them for sport for even
consume the meat from them. They are also in trouble from oil spills
and global warming. That is what I know about the Killer Whale.
