a blood-like fluid that baths the internal organs of an arthropod
crustaceans, centipedes, millipedes and insects - Most important to vet parasitology
mites, ticks, spiders and scorpions - Most important to vet parasitology
Auatic arthropods - serve as intermediate hosts for helminths parasites, including flukes, tapeworms and roundworms, also serve as causal agents as ectoparasites of many fish, amphibians, and exotic reptiles
centipedes and millipedes - produce venoms and toxic substances (sting, blind and paralyze or even kill)
largest number of members – most diverse group – important:
- may serve as causal agents
- may produce venoms or toxic substances, - - may serve as intermediate hosts for protozoan and helminthes parasites
- may serve as vectors for bacteria, viruses, spirochetes, rickettsiae, chlamydial agents and other pathogens.
- have 3 pairs of segmented legs (3 body sections – head, thorax, abdomen)
found at the anterior end (front end) - contains the brain, antennae and ventrally directed mouthparts and eyes

- contains the reproductive organs (often)
