Data Table | Body Sections(1,2,3, or >3) | Walking Legs (6,8 or >8) | Other Appendages | Antennae(0,2 or 4) | Claws Present? | Jaws Present? | Class | Common Name | Specimen 1 | | | | | | | | | Specimen 2 | | | | | | | | | Specimen 3 | | | | | | | | | Specimen 4 | | | | | | | | Beach Hopper |
Questions:
1. Many species of arachnids are predators, but have no teeth or jaws. How do they obtain nutrients from their prey?
They inject venom in the prey that paralyzes them then the predators suck out the nutrients they need.
2. Arthropods are the most diverse group of animals. Describe some characteristics of arthropods that may have contributed to their great evolutionary success.
* The body segmented, the segments usually grouped in two or three rather distinct regions - making them highly mobile.
* Paired segmented appendages (from which the …show more content…
There are about 900,000 known insect species, three times as many as all other animal species together, and thousands of new ones are described each year. They are commonly grouped in 27 to 32 orders, depending upon the classification used. The largest order is that of the beetles (Coleoptera). Next, in order of size, are the moths and butterflies (Lepidoptera); the wasps , ants , and bees (Hymenoptera); and the flies and mosquitoes (Diptera). Other major orders are the true bugs (Hemiptera); the cicadas , aphids , and scale insects (Homoptera); the grasshoppers and crickets (Orthoptera); the cockroaches (Blattodea); and the mantids
