Photographs of ticks


Ticks are members of the arachnid family, along with spiders and scorpions. They are ectoparasites, feeding on the blood of an unsuspecting host. The tick itself is not particularly dangerous, but it can carry a whole host of nasties with it so you should take care not to be bitten. They tend to climb long grasses and attached themselves to passing animals - including people.
		About 2-3 millimetres long, you have to admire a tick's ability to survive. As you can see, ticks are black so it is good idea to wear light clothing when in tick-infested areas so that you are more likely to spot them. If you are walking with your dog then you should definitely check him or her for ticks. Bloody ears are a good sign that your dog has been scratching to get rid of an attached tick.
		Once on your body, the ticks climb up to somewhere safe and warm. For some reason, the groin area seems a popular choice so make sure you check down there. When they bite, a neurotoxin in their saliva means that you may not feel them bite you as they insert their mandibles and feeding tube into your skin.
		After hiking in a tick-infested area, take a shower as soon as you can and hopefully get someone to check your body for ticks in places that you can't easily see (in your hair for example).
