Scientists Develop Zebra Barcode Reader


Scientists have developed an image scanning program that can distinguish between individual zebras by their stripes:

When a zebra has been entered into the database and given a StripeCode, the researchers match another picture of the same animal by comparing the StripeStrings of the new and original images. Each image will generate a different set of StripeStrings, but the underlying ratios of black and white should remain similar.

By finding the StripeCode with the most similar StripeStrings in the database, the system is able to accurately identify the correct animal. Other existing zebra identification systems are less accurate, more complex, and require a greater level of manual input from the user.

Amazing Armored Animals

 
Indian Rhinoceros
These massive beasts have some noticeable physical differences from their African relatives. Their segmented hide looks like a formidable coat of natural body armor. It functions a bit like one also: Flexible skin between the thicker hide “plates” allows them to shift as the rhinoceros moves.
 
Three-banded armadillo
The skin is modified to form a double-layered covering of horn and bone over many of the surfaces. Three-banded armadillos are blackish brown in color. Most animals have three moveable bands, although some possess only two, and others may have four.  Members of the genus Tolypeutes are the only armadillos that can completely enclose themselves in their own shell by rolling into a ball.
 
Thorny Devil
The Thorny Devil is on average about 20 cms long, and they feed on a wide variety of ants. An intimidating array of spikes cover the entire upper side of the body, these thorny scales are a defence against predators. Camouflage and deception may also be used to evade predation. Despite its appearance, it is totally harmless.
 
Pangolin
The pangolin (also called the scaly anteater) is an unusual mammal that is covered with tough, protective scales made of keratin. The pangolin has scales that cover everything except the belly, snout, eyes, ears, and undersides of the limbs. The pangolin has short legs with huge claws; it uses its claws to dig into ant hills and termite mounds. The sticky tongue is up to 27 inches long. The pangolin ranges from 24-62 inches long. The pangolin has no teeth. The long tail is prehensile; the pangolin can even hang from its tail.
