See how spiders and scorpions are called close relatives!
Here is how simple it is! lets reveal the magic of classification.
THEY BOTH ARE ARACHNIDS
Yes, they both are arachnids. It means that they belong to the class arachnida. What? What are arachnids bla bla!
Don’t worry, wild web members; I'll clear. First, you have to clear the doubt that spiders are not insects.
Actually, like insects are a group (known as class in scientific language) of bugs you see around, like cockroaches, ants, bees, they are insects.
Like insects, spiders have a separate group which includes spiders, mites, harvestmen and even scorpions.
Now you would have understood what I am trying to say. Neither scorpions, nor spiders are insects. Their group is called arachnida. That’s why we call them relatives or cousins.
Now, obviously, you have a question. What characteristics make scorpions and spiders relatives and separate from the group of insects?
Let's solve it!
WHAT MAKES SPIDERS SEPARATE FROM INSECTS?
Scientists who study different species of animals and classify them into certain groups are called taxonomists. They arrange them in order through observing their specific characteristics.
For example, an ant has three pairs of bodies, six legs in three pairs, and a couple of antennae. Butterflies, bees and beetles also have the same structure as ants.
So taxonomists, by examining these factors, have put them in a group and named it insecta, in which all the insects are included.
It means that, the more relevant is creatures characteristics, behavior, and anatomy. The more they are known to be close to each other.
"Spiders and scorpions belong to the same group arachnid"
THE SAME APPLIES TO ARACHNIDS
But, if we look at the spiders, they have two pairs of body parts, eight legs and no antennae. The same goes for scorpions. They too have two body parts, eight legs and no antennae.
That’s why taxonomists put them in a remote group, separated from insects.
Remember that classification is not only on the basis of outer structure. Other factors such as metabolism, diet and behavior are also considered.
CONCLUSION
I hope that you’ve understood what I am trying to say to you. If you want more amazing facts about animal classification, ask me in the comments and I'll bring you a super-info article about that.
