Bats
A bat is beautifully soft and silky; I do not know any creature that is pleasanter to the touch or is more grateful for caressings, if offered in the right spirit. - Mark Twain
The body of a bat
A bat has pokey ears, gray fur, and big umbrella-like wings. It has little feet, pink mouth, sharp teeth.What bats eat and who eats it
Bats eat berries, fruits, insects,
fish and flowers. The adaptations that
they use are sharp teeth, and echolocation.
A bat uses its wings as a net to scoop insects into its mouth. Its
predators are snakes, hawks, owls, eagles, and raccoon's. It protects itself by using its sharp teeth
and flying fast and high.
Life of a Bat
Bats grow up so fast! In 2 months a bat becomes an adult size. The mother bat carries her babies for the first few days of life. They leave their mom in one month. Did you know that they live in a quiet
cave? Bats live more than 20 years! They live in trees, caves and all over the world except Antarctica.

Blood
Blood can be scary and revolting to many. But it has four major functions:
- Fights off invaders
- Warms up and cools down the body
- Carts away waste
- Brings oxygen and nutrients to parts of the body.
Blood group
Blood groups can be categorized in many different ways. One well known system is the ABO system developed by Landsteiner. In this system, blood groups are categorized based on their antigens. After ABO system, many more systems have been discovered like the Rh system.
DId you Know: Today, there are over 150 types of classifications for blood like MN system, Kell System etc.
