Dolphins are mammals because the babies drink their
moms milk. They are also mammals because they
breathe air in and out of a blow hole on the top of their
head. Dolphins are carnivores because they eat meat
such as fish and squid. Dolphins use camouflage to
protect themselves from predators. Dolphins also have
to get used to the other animals that live around them.
They are made with flippers and fins so they can
swim. They do not live in a neighborhood because
they don’t have salt water in ponds. They also don’t
live in ponds because it would be too shallow for
dolphins to swim around.
Dolphins live in oceans and there is a lot of sea
weed. It is full of sand all over the place. The ocean
is usually very cold as the temperature is about 39
degrees Fahrenheit or 2 degrees Celsius. There are
many other fish that live in the ocean with the
dolphins. The ocean is very deep.
Dolphins are killed for there blubber which is
fat. They are also caught for their oil.
Fishermen also kill dolphins when they are
fishing.
What is being done to help them?
People are putting dolphins in protective places
such as Sea World and wildlife centers. You can
also use symbolic adoption to help save real
animals. You can get a defender’s membership and
that also saves real animals.
Because the forty species of dolphins are so diverse, they
range in size. Five species of dolphins live in the world’s
rivers. Scientists believe that dolphins conserve energy by
swimming alongside ships. Usually a dolphin has 1 calf,
twins are rare. They are mostly gray with a darker back
than the rest of its body. It is difficult to estimate the
population numbers since there are so many different
species. The Bottlenose dolphin can live over 40 years, and
the Orca can live to be 70 or 80 years old!!!! To prevent
drowning while sleeping only half of a dolphins brain stays
awake while the other half goes to sleep to keep breathing.
They are highly intelligent. The smallest of the dolphins
species is the Maui dolphin. Most dolphins live long lives.
Mating season is throughout the year.
