and &#8220;pous&#8221; (meaning foot)<\/strong>. They are found in many places like land, sea, and air. There are a lot of different types of arthropods \u2013 in fact, there are one million known species, making them the biggest group of animals on Earth. They make up more than 80% of all animal species, and two-thirds of the named species on our planet. Among all these different types, insects are the most common in the animal kingdom.<\/p>\n<p>Arthropods have a body structure with three layers, and their bodies are symmetrical on both sides. They also have segmented bodies with hard outer coverings made of a substance called chitin, and their limbs are made up of segments that can bend, which helps them move. These unique features are a big reason why arthropods have been so successful and able to adapt to different environments.<\/p>\n<p><img loading=\"lazy\" class=\"alignnone size-full wp-image-667679\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/08\/Arthopoda.png\" alt=\"Arthropoda \" width=\"619\" height=\"403\" srcset=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/08\/Arthopoda.png 619w, https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2023\/08\/Arthopoda-300x195.png 300w\" sizes=\"(max-width: 619px) 100vw, 619px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Evolutionary_advancement_over_annelids\"><\/span>Evolutionary advancement over annelids<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Arthropods are more advanced in evolution compared to annelids because they have certain special features like:<\/p>\n<ol>\n<li>Putting their sensory organs and brain parts mostly in their head.<\/li>\n<li>Having parts like legs and arms that can bend and move.<\/li>\n<li>Muscles that look striped.<\/li>\n<li>Having a tough outer covering made of a hard material called chitin.<\/li>\n<li>Having special breathing structures.<\/li>\n<\/ol>\n<p>These changes make it easier for arthropods to talk with chemicals called pheromones and react well to what&#8217;s happening around them in their environment.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Habitat\"><\/span>Habitat<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Arthropods, like insects and spiders, can live in many different places like the ocean, lakes, and on land. They have bodies with parts like legs and claws that help them do different jobs, making them come in lots of different types. Spiders, for example, don&#8217;t have feelers. Arthropods look the same on both sides and have tough outer parts that are split into sections.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Metamerism_and_tagmata\"><\/span>Metamerism and tagmata<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>One important thing to know about these creatures is that their bodies are divided into three parts: the head, thorax, and abdomen. Another interesting fact is that they have body segments and special parts that do different jobs. One cool thing they have are parts that work like levers and muscles to help them move, which is something new that evolved in the group of animals they belong to, called Arthropods.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Exoskeleton\"><\/span>Exoskeleton<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Arthropods have a tough outer covering made of a substance called chitin, which helps protect them from drying out and from things that might harm them on the outside. They grow by getting rid of their old outer covering in a process called molting. Inside their bodies, there&#8217;s a space where important things like reproductive organs and waste removal parts are located, and it&#8217;s not very big. Another part inside them is filled with a liquid called hemolymph, which comes from when they were just tiny embryos and their bodies were forming.<\/p>\n<p><a href=\"https:\/\/infinitylearn.com\/surge\/articles\/biology-articles\"><button class=\"btn btn-dark mx-2 my-2 px-4\" style=\"border-radius: 80px;\" type=\"button\">Biology Articles<\/button><\/a> <a href=\"https:\/\/infinitylearn.com\/surge\/articles\/heart\/\"><button class=\"btn btn-dark mx-2 my-2 px-4\" style=\"border-radius: 80px;\" type=\"button\">Heart<\/button><\/a><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Functional_systems\"><\/span>Functional systems<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ol>\n<li>The digestive system has three parts: the foregut, midgut, and hindgut.

They might have gills if they live in water, or tracheae and book lungs if they live on land.<\/li>\n<li>The blood system in these animals is different. They have a heart in their back, and their blood has a special pigment called haemocyanin. This is true for creatures like spiders and crabs.<\/li>\n<li>Getting rid of waste in their bodies is done differently too. Land animals use something called Malpighian tubules, while water animals use coxal glands and green glands.<\/li>\n<li>These animals also have a nervous system. They have a nerve ring and a strong nerve cord on their belly. They also have good sense organs like antennas, simple eyes, compound eyes, and statocysts.<\/li>\n<\/ol>\n<h3><span class=\"ez-toc-section\" id=\"Reproduction_and_development\"><\/span>Reproduction and development<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Most are unisexual with internal fertilisation and are oviparous.

Examples include Palamnaeus, Aranea (garden spider), and Sarcoptes (itch mite).<\/li>\n<li><strong>Class Crustacea:<\/strong> Creatures falling under this class are predominantly aquatic and exhibit a wide range of forms.

Examples include Julus, Spirostreptus, and Spirobolus.<\/li>\n<li><strong>Class Hexapoda or Insecta:<\/strong> The largest and most diverse class, Hexapoda, commonly known as insects, dominates the animal kingdom.

Arthropods&#8217; impact extends economically and ecologically, with species like honeybees, mosquitoes, and silkworms playing pivotal roles. Their innovative traits, including cephalization and protective exoskeletons, underscore their ability to conquer diverse habitats.
