Acarian

Acarian

The term acarian refers to a group of invisible but microscopic creatures that are born, feed, reproduce, prey on each other, and die in a micro planet. According to a professor at the National Museum of natural history, there are currently about half a million known species of the acarian, and acarologists believe that their number could possibly be twice as much. They are linked to be distant relatives of the crustaceans, and they have predators, prey, as well as scavengers like crustacean counterparts.

Some interesting Acarian facts

In the micro-planet that the acarian exist, they have highly adapted to the environment. Each species of the acarian has its specifity, and each one has its shape, where some are ovoid and others resemble minute spiders or worms. According to researchers, their closet relative is the red spider mite, which is actually an acarian. The most visible relative of the acarian order is the tick, can grow up to almost 3 centimeters by feeding on its host's blood. On the other extreme of the acarian organisms, the smallest acarian organism is found in the trachea of a bee. It is so minute, and with millions of species of acarian organisms, they are virtually omnipresent. They can be found on any kind of organic matter including plants, animals, soil, and water. In fact, because they do not have the wings to fly like insects, they are adapted to living anywhere except in the air. Scientists have located different species of acarian from the Antarctic ice to the super-heated water on ocean floors. Between the two extremes of the scale of the acarian organisms, there are literally hundreds of thousands of different species exist. Unsurprisingly, not all the species are harmless to humans. In fact, the immediate environment humans live in boasts of more than thirty known species. The house dust mite is among the most familiar companion. Humans have lived with the acarian for as long as the human race has existed, and it will not be amusing to find out that every day, the acarian are responsible for feeding on the dead skin that people exfoliate.
