By:Andrew Lee, Noah Martens and Simon Netznick

Define Arachnid● What is an Arachnid's characteristics?

– Have a hard exoskeleton.– Jointed appendages (used to walk)– Have eight legs– Have no antennae– Some have parts that inject venom into others– Only have 2 body parts cephalothorax and

Scorpions

Scorpions in General● Characteristics of a scorpion.

– Some are poisonous.– They have a tail.– They prefer a hot climate.– They usually travel in colonies.– A small number of them are actually dangerous

to humans.– Most if not all scorpions that can hurt humans

are small.

Scorpions diet and defense/offence

● What do scorpions eat?– They mainly eat any bug they can find.

● How Scorpions defend themselves.– They don't really defend themselves they just kill

the predator by stinging it or attacking it with their claws so basically their offense is their defense

– They're offense is they stab their opponent with their pointed tails or attack with their claws. (even if they aren't poisonous) Then they can dig in.

The parts of a scropion● What the parts are and do.

– There is a part of scorpion called a telson this part lies on the end of its tail and holds the venom

– This part is near the mouth and you may define as its “claws”

Here is an emperor scorpion

This is a very simple diagram of a scorpion

SPIDERS

Spiders in General● Characteristics of a spider

– All spiders spin silk,but most of them spin silk by using the spinnerets under the end of the abdomen so they are able to spin silk behind them.

– Most have 8 eyes but some have less or none– They can only eat liquids because they lack

chewing parts of their mouth

Different kinds of spiders● How many?

– There are more then 40,000 different kinds of spiders throughout the world!

● Famous spiders– The Biggest Spider in the world is called the Goliath spider

it is 1foot long! And its fangs are 1in long!– The most poisonous spider in the world is the Brazilian

wandering spider it can kill a mouse with 0.000000021oz. Of its venom!

– Then of course the famous tarantula known as a big hairy spider.

A Spiders Defense and Offense● Defense & Offense

– A spider uses these tactics to get away from a predator: it can run away,hide with its camouflage, or even scare its predator away.

– Then it catches prey with it's web. Then waits till its prey is stuck it then goes up to it and injects venom into it so I cant get away. It wraps it's prey up in a web and saves it for later.

– Some spiders just steal food from others

A Spider's Diet● What different spiders eat

– Most spiders eat insects– Some eat birds or mammals– Some eat other spiders– Some eat worms and/or leaves

Parts of a spider● The parts and what they do.

– They have the same things as normal Arachnids like a: cephelathorax, abdomen, and eight legs.

– They're fangs are called Chelicera.– They have Palps used for mating.– Most have eyes but some don't they most eyes

spider can have is eight.

Mites

Mites in General● General stuff about Mites.

– They are small most being microscopic.– Only some are parasites. (mainly on birds and

other mammals)– Feed on outer skin.– Pass on old and make new diseases.

Diseases mites spread● The diseases

– Scabies is one diseases and its symptoms are: inflammation of the skin,and dry and itchy skin

– Then there are mites such as dust mites that trigger allergies.

A mites life cycle● They start as eggs● When the hatch they have six legs● They grow into adult hood by shedding.

A mites diet● A example of a mites diet from a dust mite

– They enjoy eating your skin.– We shed 35,000 cells of skin every day,which is

enough to feed almost 1 million mites.– They don't have a digestive system so they

digest outside their body– Their food eventually=allergens

Ticks

Ticks in general● All 'bout Ticks

– They are tiny little bugs the crawl on your body find a spot they like and drink your blood (so like vampires but real).

– Ticks spread many diseases the one most commonly known as lyme disease

Life cycle of a tick● It starts in an egg● Then, a larva with six legs● Then a eight legged larva called a nymph● Finally, it reaches adulthood

The life cycle of a tick Part II

A ticks diet● What and how it eats

– It eats by latching onto something or someone and using the thing they latched onto called a “host” to feed themselves.
