ASL What is an Arthropod?
What do spiders and lobsters have in common? It may surprise you to learn that these two animals actually fall into the same phylum: arthropods! In this video for kids, you will learn lots of interesting facts about the many different arthropods that live around us. Of all the groups of animals, arthropods are the most diverse. There are over a million different species!
Insects, arachnids, and crustaceans are the three largest groups of arthropods. Crustaceans, of course, live in water. Insects and spiders live on land. In fact, you can find arthropods in every habitat on earth! Some can easily live in really cold, frigid climates while others thrive in the heat of the hottest desert! Which ones live near you?
Most arthropods are segmented into three sections: head, thorax, and abdomen. Arthropods also have a nervous system with a brain and nerves! They also have a circulatory system and a digestive system. Speaking of food, their diets vary widely depending on the species.
Some eat plants, some eat animals, and some eat both. Usually, they have some form of appendage that helps them get food into their mouths. And there are others, such as some species of spiders, that have an appendage specifically for inserting venom into their prey. Ouch!
