- To study the external anatomy of an Arthropod
- To understand what an Arthropod looks like
- Look for similarities between organisms of the same phylum
- Look for differences between organisms of the same phylum
The scientific name of a grasshopper is Caelifera. Depending on the type of species of grasshopper will determine the other part to the scientific name. The scientifc name of a crayfish is Astacoidea. The habitat of an arthropod is numerous and varied from anything that is not under extreme conditions. There is a picture below to show the various habitats. The predators of grasshoppers and other arthropods are lizards, birds, rodents, and spiders. The prey are grasses since grasshoppers are herbivores. Arthropods are so diverse and so widespread that there is no one niche that is covered between all, so there is a large number of niches an arthropod can have depending on the ecosystem. Many adaptations include hard exoskeleton, segmented bodies, open circulatory system, and etc. The link below the picture is a link describing the evolutionary relationships between arthropods.
Functions Of Integumentary Organs
1. Exoskeleton: To protect inside organs
2. Head: Site of majority of sensory organs
3. Thorax: Body segment with wings and legs attached.
4. Abdomen: Part of body that contains reproductive and digestive organs.
5. Antennae: Detect smell,touch, and movement.
6. Legs: Enables movement
1. Grasshoppers can be as big as 5 inches long.
2. Grasshoppers go through 3 stages of development when being born.
3. Grasshoppers make sound by rubbing their wings or legs together.
4. 350 different species of crayfish live in the United States
5. 500 different species of crayfish live in the world.
6. There is a crayfish called dwarf crayfish that is very small.
Grasshoppers serve as a high-protein, nutrient-rich source of food for people in parts of Africa, Asia and the Middle East. When large numbers of grasshoppers decimate crops, humans can eat the grasshoppers to avoid starvation, but that's not the only time the insects serve as entrees.
