Not many do though. I’m only aware of one in Australia, but there may be others.

Blood is rich in oxygen.

so they can drink oxygen?

I’m no tick expert but it would seem likely that they can extract all they need from the blood.

Ticks breathe through spiracles, which are small holes on the back and/or rear of the arachnid. This is a common invertebrate form of breathing.
