CLASSIFICATION ANIMAL BASED ON HOW TO
REPRODUCING
Types of animals have a lot of
virtually unlimited diversity. It can be seen from body shape, body color, body
size, food, how to adapt, behavior and habitat. Basically the grouping of
animals is divided into various kinds, the grouping of animals is divided
according to the food eaten, the number of feet, the breathing apparatus, the
living place, the reproduce way and many others. One of the factors that
differentiate animals is from the way they reproducing. Animals with each other
have different reproducing ways. How to reproduce that will later distinguish
animals with animals. Based on the way of reproducing, animals are grouped into
three parts:
The first is the Animal
reproducing by eggs or often called Ovivar. This group of animals reproducing
by laying eggs. Animals that reproduce in this way are generally poultry and
some species of fish, its characteristics is to produce eggs that will hatch
and become a child, have no earlobes and do not have mammary glands for
breastfeeding. As for some examples of animals that reproducing by laying eggs
(Ovipar) are as follows: Chickens, Ducks, Fish, Lizard, Geese, Birds, and
crocodiles.
The second is an animal that
reproducing by way of childbirth or also called Vivipar. Just as humans This
group of animals reproducing by way of childbirth. In general, animals that
reproduce in the way of birth are mammals. The characteristics possessed by
animals that multiply by childbirth are childbirth or childbearing, having
earlobes, milk glands for breastfeeding, containing their children in the womb,
and breastfeeding. The examples of some animals that reproduce by Childbirth
(Vivipar) are as follows: Cow, Goat, Horse, Tiger, Cat, Whale, Dog, and Rabbit.
And the last is an animal that
reproducing by eggs and childbirth with another term is Ovovivivar. this
reproduce is a combined between egggs and childbirth because the mother lays
eggs inside her body and then will hatch in the stomach and the child out by
birth. So fertilization is done in the parent body and produces eggs and seeds are
still in the form of zygote, in a certain period of eggs containing the zygote
develop into an embryo that will develop until the child tangible and hatch in
the stomach of the mother and the child came out with the process of giving
birth. The characteristics of animals that reproduce by ovovivipar are:
fertilization done in the parent body, after fertilization formed eggs, then
zygote develops into embryo and then grow again so that the child is tangible,
the eggs hatch in the body and the child comes out with the process of being
born. Examples of animals Ovovivipar are: Snakes, Platypus, Sharks, Stingrays
and lizards.
Reproducing in animals is a
feature of animals to produce offspring so that they are not extinct, which
starts from the marriage of a pair of animals, male animals and female animals.
Each type of animal has a different way to multiply as mentioned above that is
by way of eggs (ovivar), childbirth(Vivivar) also eggs and childbirth
(Ovovivipar).
