Phylum Arthropoda Phylum Arthropoda is the largest phylum of animals – there are more than one million identified arthropod species. http://informedfarmers.com/livestock/honey-bees/ http://www.visualphotos.com/image/2x3787588/a_vinegaroon_crawling_on_the_ground

Cactus Longhorn Beetle Phylum Arthropoda Arthropod is from the Greek words “Arthros” meaning joint and “podos” meaning leg or foot. The arthropods are divided into five major groups: Class Crustacea Class Arachnida Class Chilopoda Class Diplopoda Class Insecta Cactus Longhorn Beetle (Moneilema gigas) http://fireflyforest.net/firefly/2006/11/23/cactus-longhorn-beetle/

Class Crustacea crayfish crabs shrimps sow bugs Fiddler crab; crayfish; peppermint shrimp; sow bug sow bugs

ticks scorpions spiders Class Arachnida harvestmen

mites whip spiders pseudoscorpions solpugids Class Arachnida

Class Chilopoda Scutigera coleoptrata

Class Diplopoda

Characteristics of Arthropods Arthropods have bilateral symmetry. Arthropods have an open circulatory system. Arthropods have a complete digestive system (i.e. a digestive system with two openings). Most arthropods reproduce sexually.

Characteristics of Arthropods The open circulatory system of spiders: it is an open network which means its arteries carry haemolymph, the arthropod equivalent of mammalian blood, out into the tissue spaces where it diffuses past individual cells before being collected back into the heart. There are few, if any, veins in this system and definitely no capillaries. http://www.findaspider.org.au/info/spiderblood.htm

Characteristics of Arthropods: Exoskeleton The exoskeleton is a waterproof outer covering. The exoskeleton provides protection and prevents water loss. The muscles of arthropods attach to the exoskeleton. As an arthropod grows larger, the hard exoskeleton cannot expand. Therefore, arthropods periodically shed their outgrown exoskeleton - a process called molting. http://green-buzz.net/wp-content/uploads/2011/01/Horny_Skeletons_.jpg http://www.bexar-tx.tamu.edu

Characteristics of Arthropods: Appendages Head louse - Pediculus humanus (SEM) The appendages of arthropods are jointed and highly specialized for moving, obtaining food, reproducing, and sensing the environment. Most arthropods have antennae that are appendages attached to the head containing sense organs. http://www.sciencephoto.com/media/372074/view http://www.sciencephoto.com/media/367471/enlarge
