FC: Arthropods | By: Harry McMahon, Shelbe Fowler, Amina Horam, and Dalton Brans

1: Characteristics of Arthropods All arthropods have exoskeletons, segmented bodies, and appendages. An arthropod is an invertebrate that has an external skeleton, a segmented body, and jointed attachments called appendages. Exoskeleton is made of chitin. Exoskeleton protects the animal and helps prevent evaporation

2: Centipedes and millipedes Millipedes have 80 segments. Millipedes are herbivores and can roll into a ball and form a smell to defend themselves. Centipedes have over 100 segments, They are swift predators with sharp jaws and venom.

3: All Arthropods have segmented bodies with appendages. Arthropods and segmented worms may not be closely related. They however live almost everywhere. Some are adapted to live in fresh water or saltwater.Very few insects live in water, but live everywhere else.

4: A Crustacean is an arthropod with two or three body sections and usually three pairs of appendages for chewing and five or more pairs of legs. Crustaceans are the only arthropods with two antennas. Most crustacean start as microscopic animals. They develop by metamorphosis. They obtain food in many ways. Many eat dead organisms. Others are predators.

5: Arthropods have been on earth for 540 million years. DNA evidence that segmented worms and arthropods are not closely related. This scorpion is an arthropod

6: Arachnids are arthropods that have only 2 body sections. The first if the head, and the second is the abdomen. All of their organs are in the abdomen. All arachnids have 8 legs but no antennae, and they breath with organs called book lungs, which are tubes that run throughout their bodies.

7: Spiders: All spiders are predators, most of which eat insects. Most spiders make webs and wait for their prey to entangle themselves in the web, while others actually run down their prey. While all spiders have hollow fangs, only some of them can inject venom into their victim. Most spider bites however, aren't lethal, and the more dangerous ones would only hospitalize you.

8: Mites: Mites are tiny arachnids that will give you an itchy rash if you get bitten by them. Some examples of mites would be chiggers or ear mites. Most mites are parasites, and the ear mite is no exception. Many of them are microscopic though, and some people are actually allergic to their exoskeletons.

9: Ticks: Small parasites that suck the blood of a specific animal. Most species of land animals have some type of tick that suck their blood. | Scorpions are arachnids that live in hot climates. They come out from their hiding spots at night, and they hunt. To kill their prey, they use a stinger to inject venom. Most aren't too serious.
