Transcript of What is a Arthropod?

What is a Arthropod?
A arthropod is an invertebrate animal which has a exoskeleton, segmented body, and jointed appendages.
Types of Arthropods
There are many types of arthropods. There are 5 main classes which are insects, Arachnid, Crustacean, Diplopoda, and Chilopoda.

My project
I had to do a lot of searching to find all of my specimen. When I finally caught all of my specimen I took them and soaked them in rubbing alcohol (to preserve them). Then I hot glued each one of them in a section of the plastic showcase. On the lid of the showcase I labeled the specimens common name and scientific name.
Arthropods and there role in the environment
What I have learned
I have learned a lot doing this project. I have learned there are many different types of arthropods. They help us in so many ways and they interact with other organisms. With out them it would be a disaster and no good.
Arthropods have many different body parts. Each one is designed different for different purposes. The 3 main parts is the head, thorax, and abdomen.
Arthropods Body
insects are in the class Insecta. Insects have 3 pairs of legs and a body segmented into head, thorax, and abdomen. this includes butterfly's, Dragon flies, Bees, praying mantis, Grasshoppers, and etc
They have a single pair of elongated legs attached laterally to each segment. They have a pair of thoracic legs converted into poison fangs. These include centipedes. They are very active and have many legs.
Arachnid have four pairs of segmented legs and a body that is divided into two regions, the cephalothorax and the abdomen. This includes spiders, scorpions, mites, and ticks.
A Crustacean has a segmented body, a chitinous exoskeleton, and paired of jointed limbs. This includes lobsters, crabs, shrimp, craw fish, and etc..
They have a body composed of numerous double somites each with two pairs of legs. These are millipedes.
Well habitat is there home or environment. Every arthropod is designed different for there environment. some live in a aquatic habitat like creeks and water areas. Also some live in terrestrial habitat which is like plant structural (forest & grasslands). Different arthropods live in different habitats.
Arthropods design
Each arthropod is designed different. Some are camouflage to fit there environment. This helps them hide from there predators. Some of them play dead like the spiky shell spider did when I captured it. Some have different parts to help them do things. For example a craw fish has two pincers to help them move small objects.
Importance of Arthropods
They help in many ways. They can be a good diet for humans, pollinate flowers, use for medicine, use for medicine practices, they can help control bug population, and a lot more. Some scientist say most life would not survive if arthropods suddenly went extinct.
Trees and Arthropods
Trees help arthropods for example they provide shelter for them. Also trees provide co2 for them. But the Arthropods might not be as helpful to the trees. There are chewing insects like beetles and centipedes that chew into trees. Also some of them eat the leaves off of the trees. Some of the bugs can be harmless and others can cause fatal damage.
Prey & Predators
other insects, nectar, each other, plants, animal or plant matter, and etc.. Some are herbivorous which means they eat plants. while others are carnivorous which means they eat meat such as insects.
animals, insects, plants (fly trap), and etc..
Humans & Arthropods
We eat arthropods such as lobsters, shrimp, and more. We would not be here if it was not for them. They do so many things like keep our air clean.
Arthropods have different shapes and colors. Some of them can look like sticks and leaves. Some can can be colored like flowers, leaves, and woods which means they can be camouflage. Not only do they look like stuff they have to act like it also. Some arthropods have some kind of warning like hissing roaches
Most reproduce sexually but some reproduce asexually. In asexually parthenogenesis occurs. Parthenogenesis is when an unfertilized egg can develop into a new arthropod.
Interesting Facts
They have been on earth since about 428 million years ago.
Some stride on water such as water striders.
Ants don't sleep and they are social insects
Dragonflies are the fastest flying insects
There are more than 900,000 known species of insects in the world.
Parts and Pieces of Arthropods
jointed legs
Some have wings
poison gland
These are just a few of the parts of a arthropod.
