OBJECTIVES
Caelifera - The General Information
What habitats do grasshoppers live in? Most grasshoppers prefer dry open habitats with lots of grass and other low plants, though some species live in forests or jungles. Many of the grassland species invade farmer's fields too.
What adaptations have grasshoppers made to survive better in the environment? - Grasshoppers usually have large eyes, and are colored to blend into their environment, usually a combination of brown, gray or green. In some species the males have bright colors on their wings that they use to attract females. A few species eat toxic plants, and keep the toxins in their bodies for protection. They are brightly colored to warn predators that they taste bad.

DID YOU KNOW...
Most grasshoppers can only survive the winter as an egg; the adults all die when it gets cold.
No grasshoppers are known to be endangered.

Crustacea - the general information
How do we classify crayfish? Crayfish are classified into Kingdom Animalia, Phylum Arthropoda, Subphylum Crustacea, Class Malacostraca, Order Decapoda, and Suborder Pleocyemata.
Where do crayfish live? Rivers and brooks are the main living habitat for the crayfish due to their water clarity and thin ice conditions. Freezing water conditions are enough to destroy crayfish habitat and that’s a main reason they thrive in rivers of moving water.
What adaptations do crayfish have? Crayfish have two big pincers that help tear food apart. When threatened, crayfish often raise their pincers high and wave them around. Some also use their front pincers to help dig burrows. If a crayfish loses a leg or pincer, it grows back, usually during the animal's next molting cycle.Crayfish adapted eyes on short stems that move around, allowing them to see in all directions just by turning the stems. They also have two pairs of sensitive antennae that help detect movement in the water as well as chemicals transmitted through the water.

FUN FACTS
Over 350 of the 500 total crayfish species lives in the United States alone
Crayfish are also called craw-fish, crawdads and mud bugs.
Crayfish live on every continent except Africa and Antarctica.
The colors of a crayfish can be sandy yellow, pink, red, dark brown, and blue.
