Chelicerates. Includes spiders, ticks, scorpions, horseshoe crabs, and sea spiders. Today we will study the annelids, the segmented worms, and the arthropods, a huge group that contains insects, spiders, and crustaceans. Three tissue layers are present in both of these groups.

Arthropods. Enormously diverse phylum. Many parasitic arthropods serve as hosts for a number of parasites (hyperparasitism) from cestodes to viruses. We focus on the crustaceans, insects, and arachnida.
