FLEAS
Fleas are ectoparasites, meaning that they live on the exterior of a host animal. The survive off hematophagy; feeding off the blood of their host. Fleas are part of the Siphonaptera order and go through complete metamorphosis, progressing from egg to larval stage, then the pupal stage and then finally becoming an adult. Similarly to mosquitoes, females must have a blood meal before they can reproduce. There are over 2,500 species of flea, with each individual species feeding off a different host animal.
