The science of entomology is the study of insects and allied organisms. These animals belong to the Phyla Arthropoda. Within the Phyla, there are two classes, 1. the Arachnida, and 2. the Insecta.
We performed a cladistic analysis of 25 characters to determine how the chelicerates, crustaceans, and uniramids should be classified, possibly under 1 phylum, Arthropoda, or in 2 or more phyla.
Claws and anemones may help with defense. - Must acquire larger shell as grow. Exhibit elaborate shell switching behavior, and may kill and eat snail to get shell.
The best known arthropods are the myriad terrestrial insects we encounter every day. Many marine arthropods can be found in our tidepools, though some of these arthropods are barely recognizable as belonging to the phylum.
Many arthropods have adopted the parasitic way of life. Depending on your definition of parasitism, something between 15 and 50% of insect species are either parasitic or have parasitic stages in their life cycle. Some groups of parasitic arthropods are more economically important than others.
