How does the embryo of an eagle develops?• The yolk contains the fertilized egg cell from which

the embryo forms, and is rich in proteins and fat that are the food required by the developing embryo.

• The shell not only protects the embryo but also allows the water, oxygen, and carbon dioxide to enter allowing the baby to breathe.

• After the egg is laid the cells will be alike, but then there will be changes. One cell might become an organ while the other might be a wing or a leg.

• On the second day of incubation the vascular system if formed while the heart if formed somewhere else.

• After 44 hours the heart and the vascular system will join while the circulatory system is already formed.

How does the embryo of a dolphin develops?• At the fifth week of development the hind limbs

are present as small bumps near the base of the tail.

• The fertilization is external with sperm and eggs being liberated into the water.

• Some fish have put effort into producing a small number of young at a more advanced stage, so they can survive to adulthood.

• The dolphin’s embryo passes through a stage is which they have hind limbs, but they disappear as the embryo develops.

How does the embryo of a giraffe develops?• Giraffes have only 7 cervical vertebrae. These are

followed by 13 thoracic vertebrae, 6 lumbar vertebrae, 4 sacral vertebrae, and a variable (20+) number of caudal vertebrae.

about 5 to 9 feet in diameter and they weight two tons.• Eagles build their nest on a high tree or on cliff.• After the egg is laid it takes 35 days to incubate.• The hatching process takes about 2 days and 12 hours (60

hours).• After the eaglet is hatched it has gray, downy coats, poor

eyesight and weak legs.• They cannot even hold their head up to feed for the first

few weeks.• Baby eagles grow very fast which is one pound every 5

days.

How does the young of a dolphin develops?• The tail and dorsal fin stiffens within two weeks

after birth.• Right after birth the baby dolphin weighs about 20

to 25 pounds and has a height of 2 to 3 feet.• It takes time for the baby to adapt to the

environment.• The baby raises its head higher that required on

the surface of the water to make breathing easier.• Dolphins grow by drinking their mother’s milk for

about 2 or 3 days.

How does the young of a giraffe develops?• The mother gives birth standing up.• First the head and the front legs come out then

the rest.• A newborn giraffe is 1.8 m tall which is 6 ft.• After a few hours it is able to run, however, for the

first few weeks the coat pattern provides camouflage that is why they go into hiding;.

How do eagles care for the young after birth?• Baby eagles don’t drink milk instead they eat

meat which their parents bring.• The first few months are vital because there might

be attacks from predators, so one of the parent must stay with the baby to protect.
