One of the most adaptive and resilient hitchhikers of the gruesome world of parasites is the hard-bodied tick. These hard-shelled masterminds rely on your blood because they lack sufficient energy to complete their lifecycle without indulging in a warm, crimson feast. They’re brought into the world as eggs unable to grow without latching onto a host, so they must find a small mammal or lizard in order for them to start developing.
The larva engorges itself on the fresh, warm blood of its first host before dropping to the ground exhausted and overindulged. They’re equipped with ferocious jaws yet unable to jump, so they can only lay in ambush when they need to feed again. They stretch out their clawed first pair of legs and then wait for an animal to pass, at which point they grab hold. When seeking their prey they wave their legs, looking for a signal that there is a host nearby.
You’re an easy target. She knows you’re there – the special sensory organs within her limbs can detect the carbon dioxide in your breath and the ammonia in your sweat. You’re getting closer, and suddenly she senses a spike in temperature, her cue to reach for opportunity and latch onto your skin with her tiny claws.
Beneath the protective plate guarding her soft body she is armed with a set of sword-like jaws. She settles somewhere after seeking out her favourite spots to lounge for a few days and punctures the skin with a miniscule, pointed tooth, allowing her saliva to ooze into the wound and keep your skin bleeding.
