Flea – interesting parasite


Fleas are insects that live as parasites on birds and mammals, including humans. They depend on the animal they live on for food. Fleas bite the animal and feed on its blood. They can spread diseases. There are about 1,600 species of flea. The largest individual is only about 1 centimeter long. Fleas are excellent jumpers.
A flea has four stages of life: egg, larva, pupa, and adult. A female flea can lay more than 20 eggs every day. Adult fleas live for a few weeks to about a year.
Fleas commonly spend a great deal of time off their hosts, for example, in vegetation or on the ground. They can generally survive for a long time without feeding.

Sloth – slow-moving mammal


Sloths are slow-moving mammals that spend most of their lives in trees. They live in the tropical forests of Central and South America. They belong to order Edentata, which means “without teeth.” However, they have molars, chewing teeth, that have no roots and continue to grow throughout their lives. They are related to armadillos and anteaters.
Sloths can grow up to 69 centimeters long and weigh only about 4 kg. Sloths have flat faces on round heads, with round eyes, a round snout, and round nostrils. The fur is usually grayish brown or tan. They often have a greenish tint because of algae on their fur. This helps sloths to blend in with tree leaves. Their toes have long, curved claws, which the animal uses to grasp branches.

Eyes – Mirror of Soul

Eyes - Mirror Of Soul

Eyes – Mirror Of Soul


We use our eyes to see. When we see an object, we actually see light reflecting off that object. This light enters the eye, which changes the light into electrical signals, that travel through the optic nerve to the brain. The brain interprets signals as an image, or picture, of the object. The eyelid protects the eye. By blinking, eyelids move tears across the eye to keep them moist. Eyelashes also protect the eyes from dust and other particles.
The light rays enter the curved front of the eye called the cornea, where they are partly focused. They pass through the pupil, which enlarges in dim conditions to let in more light and shrinks in bright conditions to protect the inside of the eye from too much light.
