Hello friends! Welcome to a new Happy Learning video.
Today, we’re going to meet animals that have eight legs, and are a little scary! Today, we’re going to meet.. arachnids!
Same as insects, arachnids are invertebrates and belong to the arthropods. But don’t get confused! Arachnids are part of a different animal group than insects, while insects have six legs, arachnids have eight! Like you can see in these images.
Spiders, scorpions and dust mites are part of the arachnid family, and share a number of characteristics that we need to know.
They have four pairs of articulated legs, they don’t have antennae or wings, but they do have a pair of clamps by their mouth called chelicerae (kelicera) that they use to hold their prey.
A fun fact about arachnids is that they can’t chew, so they swallow their prey by sucking them in. They suck the soft parts as if with a straw. They are carnivores, and spiders and scorpions feed from insects, other arachnids and sometimes small reptiles and mammals.
An Arachnid’s body is divided in two parts: cephalothorax, consisting of their head, and thorax, joined in a single segment, and the abdomen, that can be segmented, or not.
Arachnids breathe through traqueas or pulmonary sacs.
And when they’re born, they look the same as they do when they are adults, but of course, they are much smaller.
Scorpions are the biggest arachnids, the largest ones can measure up to 20cm.
They have huge chelicerae (kelicera) in their heads they use them to grab their prey, before they inject venom with their sting at the end of their tail.
Spiders are the most popular arachnids, but also the scariest. Most of them are venomous, but very few are truly dangerous for human beings. The truth is spiders are astonishing animals.
Also! Apart from being able to produce their famous spider web, they are able to hunt their prey in multiple ways, look look!
Dust mites are the least popular arachnids, because they are so small you can’t see them at a glance, they are microscopic, but what is true is that they’re everywhere!
In every house there are thousands and thousands of dust mites…
Well, now we know a little more about arachnids, the truth is they are very strange and mysterious animals. But, as for everything else, they are important for balance of life, of this marvellous life.
