How many legs does a rolling roller really have?

The slide - some are called "centipedes" - not worms and not insects. Insects only have six legs, and obviously the mats have more legs than that. So how many more legs does the book have?

Many respondents were 994 due to the Latin language prefix "milli-" (meaning 1,000) in this animal's name but they were wrong.

As it turned out, scientists did not choose the prefix "milli-" , to indicate the exact number of feet this creature had. The common name of the slide is "hundred feet " is also incorrect.

The specific identity of the roll is that each pair of legs has two pairs of legs.

Millipedes is a group of arthropods, a group of diverse invertebrates including spiders, scorpions and butterflies. All arthropods have a common feature: the exoskeleton, the body splits the artery and the joint. Meanwhile, the specific identity of the roll is that each pair of legs has two pairs of legs, instead of one pair as you see on the centipede. This explains the more precise name used by scientists: Diplopoda, which means "double leg".

Having a lot of legs is an element that helps to adapt to the environment. Fossil evidence suggests that rolling is one of the first terrestrial animals, meaning they have survived about 400 million years.

In the Coal Age, about 300 million years ago, a rolling species called Arthropleura developed into a two-meter-long and 0.5-meter-long creature. Today, the roll is only about 3mm to about 0.3 meters. So far, scientists have discovered about 12,000 species that are projected across the continent except Antarctica, but it is estimated that up to 80,000 species can be found.

"Each country has only a handful of rolling species that appear there, not living elsewhere" - says Derek Hennen, an entomologist for Virginia entomology at Virginia Tech. Hennen studied the rolling species and loved them so much that he even set up a Twitter account (@DearMillipede) about everything related to this animal.

Why does the book have so many legs?

The mats eat fallen leaves because this food is scattered everywhere but not nutrient-rich. This means that the slide spends most of the time in the ground, under leaves and rocks. And what makes them easy to travel in this harsh living environment? Of course, thanks to their legs .

Hennen said : "Collum (first body burning) acts as a bulldozer, and possessing multiple legs helps to further energize the body and dig deep into the ground."

The projection has many legs depending on the rolling species.

When the film was just hatched, they had only a few legs. Then, like many other creatures like crabs and spiders, rolling mat matures through a process called molting . During this process, roll out the outer skeleton and develop a new skeleton. Each time this is done, the slide also develops a new body burn along with two new legs. Some rolling species stop molting when they reach adulthood, while others lose their lifelong life - an average of about two years.

So, how many legs are there on rolling? Hennen revealed, this depends on each species rolling, but the number of legs is in the range of 24 to 750 feet.

Hennen said : "I guess those who saw this said:" This one is true! ", So I thought of the nickname that people often hear. mats are similar to centipedes, just that they possess more legs ".

In fact, most rolling species have less than 100 feet.

The difference between rolling and centipede

The slide has a number of defense mechanisms, but not bite or bite (they have very poor eyesight, some don't even have eyes and mostly use beards to find their way). The optimal response of self-defense is when they feel threatened, they will curl and secrete chemicals that repel enemies. Although the rolling chemicals are secreted differently, only a small amount is released to the extent that it is not usually dangerous to humans. Many studies describe in certain tropical regions, monkeys come to scurry to take advantage of these biological chemicals secreted to expel mosquitoes.

In contrast, centipedes can bite with small fangs that release toxins. However, even if the bite of the centipede has pain, it will not harm us.

In terms of legs, the centipede's legs tend to radiate, while the legs curl up and down. Centipedes have only one pair of legs on each body burning while rolling to two pairs. If you don't want to come close just to confirm this, Hennen advises everyone to observe the behavior of the species.If the creature ran fast, it was a centipede. If the creature is just curled up, it is a scroll .
