Meet the dinosaur nemesis—the 99 million-years-old blood-sucking ticks

You have a grand home, and are revered as a giant. You have two guests over for a visit. One pays for his food and accommodation by cleaning up after you. That’s symbiosis, and the guest is dermestid beetle larvae. The other not only refuses to pay, but also insists on sucking the lifeblood out of you. That’s parasitism, and the guest is the tick who, by the way, goes by the name of Deinocroton draculi (Greek word ‘deinos’–terrible, ‘kroton’–tick), or Dracula’s terrible tick.
