Arthropoda Phylum
-Phylum Arthropoda (arthro = joint; poda = foot) is the most populated phylum of all living organisms, both in number of individuals and number of species.
-An arthropod has a segmented body that is covered by an exoskeleton. The exoskeleton is made from chitin and other chemicals. This exoskeleton acts as protection and provides places for muscle attachment. Arthropods have open circulatory systems that consist of a dorsal heart. The dorsal heart collects blood from the body cavity and pumps it back into the body cavity again.
-Arthropods have a well-developed nerve cord and well-developed sense organs.
-This is the largest and most successful of the animal phyla, with over 1 000 000 species identified today-
-This exoskeleton protects the organs, gives support for the body, and allows for efficient locomotion. However, because the exoskeleton cannot grow, it must be shed from time to time to allow for the organism to grow.
They have a complete digestive and excretory system. They also have well-developed sensory organs, that include antennae, eyes, and ears.
-Arthropods locomote in a wide variety of ways. They can walk, crawl, climb, hop, fly, glide, swim, skate, dive.
-Arthropods can be found on every continent and in every ocean.
