WALHT: Renewing the structure of an explanation.
What is are Arthropods?
An Arthropod is animal that has an exoskeleton, a segmented body and jointed appendages. Arthropods have been living in Earth for more than 500 million years.
Examples of arthropods are insects and arachnids.
The Phylum Arthropoda group has the highest amount of population. They are living in about three quarters of all the biological organisms on Earth. The counted population of the arthropods is more than 10 million. Arthropods can be found almost anywhere in the world.
The arthropods are divided into four different categories which are the Chelicerates, the Crustaceans, the Uniramians and the Trilobites.
- The Chelicerates have two tagmata, the cephalothorax which is their head and thorax and an abdomen. Spiders, ticks and mites are examples of Chelicerates.
- The Crustaceans usually live in the water but they can be seen in land. Crabs, lobsters and shrimps are examples of the Crustaceans.
- The Uniramians have a lot of segmented body parts and examples of Uniramians are millipedes and centipedes.
- The Trilobites are Arthropods that are extinct and can only be found through fossils. The Lichida and the Asaphida are examples of extinct Trilobites.
Arthropods eat many kinds of living things. However, they usually eat herbivores (eat only plants), shredders (eat bacteria and fungi) and predators (eat other bugs). Arthropods die slowly from hunger if they are two hungry and have nothing to eat. People shouldn't give any arthropod a food because it will find what it will need.
Arthropods are very beneficial to humans they can decompose waste and make money. Arthropods should not be killed often because maybe one day we will lose this amazing creature living in our world.
