Ticks are small parasites – they look a little bit like spiders as they have 8 legs, and they feed on blood.
They do not have wings and they cannot jump. They travel by walking on the ground and up plants from where they latch onto their prey with specially designed hooks on their legs. An unfed tick is approximately 3mm (sesame-seed-size) and small, oval and flat. After a blood meal, a tick can reach 11mm in diameter with the grey/brown body extending out from the back of the thorax.
