Dolphins are carnivorous mammals that hunt fish, squid, and other prey in pods. They use echolocation and teamwork to locate and catch food. Dolphins live in oceans worldwide and have diverse diets, behaviors, and lifespans depending on their species. However, dolphin populations are threatened by fishing nets, pollution, and habitat loss caused by human activities. Conservation efforts aim to protect dolphins by changing fishing practices and reducing waste.

Dolphin Report
Dolphins are carnivores which means that they only eat
meat. The food that they eat are fish , sardines, herring, salmon,
codfish, shrimp, squid, grouper and many other fish that live
under the water. Dolphins work together as a team to get their
food. Some dolphins were use clicking sounds to the herd to
come join the feast. The dolphins will make the school of fish
into a tight group then the dolphins were circle around the fish
to keep the fish from getting away. Every dolphin takes a turn
of getting a fish. Sometimes dolphins get their food by
swimming near the surface. A bottlenose dolphin can whack a
fish up into the air with their tails to send the fish soaring into the
air. When the fish lands in the water again then it will be easy to
catch the fish. A dolphins tooth is only used to grab the food.
Dolphins always turn their food around then the dolphin will
swallow the fish whole. The dolphin usually goes for the head
first. Dolphins will also eat octopus to. Dolphins have very sharp
teeth that are on the upper jaw and the lower jaw. Dolphins
can crush their prey at very fast speed. Dolphins use a very
special skill to find their prey they will use their sonar this can
show the dolphin the size, the speed, the shape and the
direction of the prey. A dolphin’s favorite prey is fish and squid.
Dolphins are amazing predators. Bottlenose dolphins will rush up
to the surface to grab a fish. Some dolphin species will feed on
fish and cephalopods. Dolphins will also eat cuttlefish. Some
Dolphins have a varied diet. A diet that includes squid, crabs,
shrimp, lobsters, and rays. Dolphins will also take down sharks.
Dolphins can be seen in every ocean in the world. Some
dolphins usually live near cold waters but other dolphins spend
their whole lives out in open oceans. Some dolphins can be
found in tropical and temperate waters. They can usually be
seen in the Mediterranean. Some dolphins can even be seen in

2. the polar waters. Dolphins do not migrate in very long distances
some dolphins can migrate about hundred miles in a search of
a meal. The dolphins that live in the freshwaters they are only to
be found in very big rivers that are in Asia and in South
America. Some dolphins like the Ganges River dolphins are very
blind. This dolphin will use a long snout to look for food in the
bottom of a river. Dolphins can be found in very warm oceans
around the world. The real common place to look for dolphins is
in the deep off shove waters. They can also be found in shallow
waters. Some dolphin populations have a present in all year
round. The Bottlenose dolphin lives near the coast and in the
Northern Cape Hatteras to the Southern of Florida and the
westward that is through the Gulf of Mexico. The dolphins other
location is near the continental that is off coast of New Jersey.
Bottlenose dolphins can also live in many different places of the
life cycle which is responding or giving birth. A dolphin’s length
is 1.7-2.4m. Their weight is up about 75kg. The biggest dolphin in
the world is the killer whale it can grow about 23 feet (7 meters)
long. The smallest dolphin is the Heaviside dolphin it can grow
about 3, 5 feet (1, 2 meters) long. The weight of a killer whale is
4, 48 tons and (4, 55 tons). The height of the Heaviside’s dolphin
can grow about 88 pounds (40 kilometers). The dolphins rather
size is 1.2m (4ft) and 40kg (88lb). The Maui dolphin can grow
about 9.5m (30ft) and 10 tons this also the weight of the killer
whale too. The average length of the North American dolphins
can grow about 13, 89 feet in a length. Some species can
weigh about 50 to 200kg (110 to 440 lb).The bottlenose dolphin
can grow about 12 feet (3. 7m) long. Sometimes their weight
can be about 1,400 pounds (635 kg). The killer whale can grow
about 3½ feet long and 88 pounds. Dolphins can live about 25
years. A life span of a dolphin depends on the species. They
can live about 20 and 90 years. The other life span of dolphins is
also 12 or 80 years. The Bottlenose dolphin can live about 50
years. The killer whale can live about 80 years. The bigger
dolphins have a longer life span then smaller dolphins do.
Dolphins can also live about 50 years. Dolphins have two
stomachs. One stomach is to in store food the second stomach

3. is to digest. Dolphins are social animals they live in a group
called a pod it can hold about 10 to 50 animals. Some dolphins
have schools which can hold about 100 and 2000 animals.
These groups are very social with each other these groups will
also have fun activities together, like surfacing, jumping and
splashing each other. The typical dolphin’s behavior also
includes breathing, tail-slapping, chin-slapping bow-riding and
proposing. Dolphins are very fast mammals they can swim
about 40km 1h. Dolphins are known to use both speed and
their groups to catch their prey. When dolphins go to sleep
then one hemisphere of their brain shut’s down. The dolphin will
remain conscious enough for the dolphin to breathe air and
look for predators. Dolphins usually sleep in the ocean then
they will sink then they would not be able to breathe. Because
their body and their bones are very structure. This is how
dolphins get more oxygen then humans do. Dolphins can float
above the water about (25 centimeters). That is below the
surface of the water. Every dolphin has sounds that can travel
under the water it is called echolocation this is the kind of
sound that bats can use to. This sound helps the dolphin locate,
the size, speed and the shape of object, this bounces off
something and then it returns back to the dolphin. Dolphins live
and play in schools that can hold 5 hundred animals. Some
dolphins can swim and roll in format. Dolphins can also help
each other when one of the group members is sick, hurt, or
giving birth. A group of Dolphins can even ram a shark. Even a
very big shark. Dolphins have many predators like the tiger
shark, Dusky sharks, bull sharks and the killer whale. Dolphins
love to have fun and play. They sometimes can play with
seaweed or play a game of fight with each other. They can
even play with other sea animals like turtles, fish, seals, birds and
even whales. Dolphins will play with an animal even though the
animal does want to play or not. Even adult dolphin will love to
play and have fun. Dolphins love to ride and leap on the waves
that are created by ships and boats that are moving in the
water. They can even body surf through the waves that are
made by human surfers. Dolphins can easily learn human

4. games. Sometimes dolphins can come up with their own
games to play with humans. Dolphins are really close related to
whales. They are mammals. You can till that they are mammals
because they have a blowhole on top of their head that helps
the animal breathe. When the dolphin goes underwater then
the blowhole will close so that the dolphin does not drown.
Dolphins are warm-blooded and they can give birth to live
babies. Dolphins are the smartest animals in the world. Dolphins
have very good eye vision they can see very will underwater
and up in the air. There underwater vision is like a cats or dogs
eye sight. The dolphins that live in the river do not have very
good eye vision because they live in murky water so using their
good eye vision would not be a good idea. A dolphin’s
gestation period is usually to 10 or 12 months. A newborn
dolphin is about 10 to 400 pounds. (4.5 to 180 kilometers). The
dolphins other gestation period are about 12 months, they are
able to wean in about 9 months. Dolphins will start to breed
when they are the age of 8 years old. Females only have one
calf though out their whole lives. They will stop having babies
when they are 14 years old. New born dolphins can grow
about 35 and 50 inches long and they can weigh about 30 and
50 pounds. Dolphin mothers can be very protective because
the calf can quickly swim away and they can get lost in the
open ocean. They also get attack by sharks. So mothers have
to keep a close eye on their young all the time. If the baby
stays to close to its mother then the mother will get trapped
between her flippers or she can hold on to it. The baby can
stay under water about seconds. The other females in the pod
are now called aunties. Their job is to help protect the baby
from getting into danger. Females can make a playpen by
swimming around in a circle so that the babies can play safe.
Dolphins are in trouble today because they are being hunted.
Dolphins are also in trouble because they are getting caught in
fishing nets these nets are used to catch dolphins too.
Fisherman usually catch them when they are underwater so
that the net can drown the dolphin. Fisherman will use their
nets to snag any underwater animal that ever swims by. A

5. dolphin worst enemy is people. When a fisherman catches a
dolphin then the dolphin often dies. Most of the time when a
fisherman mistaken a dolphin for a fish they often do not try to
save the animal that they catch in their nets. Dolphin’s habitats
are also about to disappear because of fishing nets and
people are hurting them. People sometimes use bait to catch a
fish. Dolphins are also in danger because of pollution and the
people are dumping their garbage into the ocean this is really
bad because dolphins will eat the garbage and then they will
get sick and die. People are dumping their garbage over
dolphin’s habitat this is causing too much trouble for the
dolphin population. During the 1973s and 144,000 dolphins
have died from fishing nets. The Marine Mammal Protection Act
is making laws to force commercial fisherman to change their
fishing techniques to reduce deaths from dolphins. People that
live in China, India and in the Amazon think it is very important
to protect river dolphins in these areas. There are lots of people
that admire and care for dolphins. We have to hope that these
amazing marine mammals can be with us for the years to
come. The bottlenose dolphin population is starting to go at
low risk of survival. That is what I know about dolphins.
