[Music] [Applause] [Music] hello friends welcome to a new happy learning video today we’re going to meet animals with eight legs and they’re a little scary today we’re going to meet arachnids [Music] 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 [Music] spiders scorpions and dust mites are part of their arachnid family and share a number of characteristics that we need to know [Music] they have four pairs of articulated legs don’t have antennae or wings but do have a pair of clamps by their mouth called cholestera 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’ve carnivores and spiders and scorpions feed from insects and other arachnids and sometimes small reptiles and mammals an arachnoid’s body is divided in two parts cephalothorax consisting of the head and thorax joined in a single segment and the abdomen that can be segmented or not arachnids breathe through tracheas or pulmonary sacs and when they’re born they look the same as they do when they’re adults but of course they are much smaller scorpions and the biggest arachnids the largest ones can measure up to 20 centimeters they have huge cholesterol in their heads and use them to grab their prey before they inject venom with their sting at the end of their tale [Music] 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 spiderweb they are able to hunt their prey in multiple ways look look [Music] 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 are 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’re very strange and mysterious animals but they’re important for the balance of life for this marvelous life [Music] goodbye friends see you next time and don’t forget to subscribe to happy learning tv [Music] [Applause] [Music] you Video source: https://www.youtube.com/watch?v=6k-0yaLrJjI
