The Chorthippus brunneus (common grasshopper) are found all over in North America, Europe, Asia and Northern Africa. They have three pairs of legs with a pair of antennae and segmented bodies. This specific species of grasshopper play a vital role in feeding and consuming organisms in its food chain. There are either male or female grasshopper that reproduce using sexual reproduction
The Procambarus clarkii (common crayfish) have segmented bodies and four pairs of legs that include a pair of claws. They prefer freshwater and are found mostly in the south eastern United States. This specific species of crayfish play a vital role in consuming and feeding organisms in its food chain. There are either male or female crayfish that reproduce using sexual reproduction.
ecological niche of grasshopper
The niche of a grasshopper involves stabilizing the food chain by being omnivores and consuming it prey. They also stabilize their food chain by being consumed by its predators. Another vital role to their niche is reproducing because their offspring will have the same niche that is just as important.
ecological adaptation of grasshopper
Hind legs allow grasshoppers to jump twenty times their length.
Camouflage allows grasshoppers to blend in with their surroundings.
Wings help with mobility when grasshoppers jump.
ecological adaptation of crayfish
Crayfish have adapted to murky waters by having their eyes on short stem. The stems allow the eyes to move around to see better.
Crayfish have a pair of antennae that are sensitive to movement.
Camouflage allows crayfish to blend in with their surroundings.
evolutionary relationships of grasshopper
evolutionary relationships of crayfish
Students will classifying various arthropods such as grasshoppers and crayfish. They will also observe their external and internal anatomy of the specimens and be able to identify each part. The links below provide great information about arthropods and this assignment.
Circulatory System of Grasshopper
Grasshoppers have an open circulatory system where blood Flows freely through the body which begins at the hemolymph. It then goes through large blood vessels, into the coelem, to the abdomen and finally the heart.
Circulatory system of Crayfish
Crayfish have a open circulatory system which means they have no veins or arteries and blood flows freely through the body. Begins at the blood starts at hemolymph, then goes through large blood vessels, into the coelem, to the abdomen and finally the heart.
Classifying Arthropods in Person
Classifying arthropods during the lab ended up being really interesting and allowed me to see each body part of the specimen in person. This ended up being a great hands on experience and I learned so much from it.
