Mammals Vertebrates Animal Kingdom. Fauna.



Mammals are the most evolved animals of all that exist, with some 5,000 different species worldwide.
Its size ranges from 4 centimeters for the dwarf shrew to 30 meters for the blue whale.
This evolution and variety have allowed them to conquer all environments on earth, both the continents and the seas and air.

General Characters

The common characters are:

Some distinctive features of mammals

The lower jaw is made up of a single dental bone.
The epiglottis is a valve that closes the entrance to the trachea.
A muscular septum, the diaphragm, separates the abdominal cavity from the thorax.
Almost all mammals have seven cervical vertebrae, regardless of the length of the neck.
The ear of mammals has three ossicles:

Some mammals have hair changes, depending on the seasons of the year.

Horns and antlers

The horns are hollow, bony protrusions that emerge from the skull and never fall off.
Some horns are made up of modified and fused hairs.
> Antlers appear as buds on the skull and grow as spongy tissue that calcifies or hardens into bone.
The antlers are shed annually and new ones come out.

Development of mammals

Mammals have viviparous reproduction (except monotremes).
Its fertilization is internal through the copulatory organ of the male.
The baby before being born develops gradually in the mother's body, within several envelopes, and receives food from her through the placenta, and is protected by a bag full of water: the amnion.
After being born the young are suckled, taking milk from the mother's mammary glands.
In this table you can see the differences between the gestation periods and the number of offspring of a series of mammalian species:

Gestation periods and offspring of some mammals
House mouse 9 days 5-7 pups
House cat 2 months 4-6 pups
Dog2 months 2-4 pups
Porcupine 2 months 2-4 pups
Deer 2 months 1-3 calves
Male 9 months 1 calf
Whale 10-12 months 1 calf
Elephant 24 months1 baby
