I think our largest native tick is the ornate kangaroo tick, the female is about 5 mm long before feeding. Not sure if that counts as a giant. The largest tick in the world is the sloth's giant tick; one specimen was found to be the size of a walnut (after feeding). Makes sense, ticks rely on not being detected by their host, so there's a strong selection pressure against getting too big - but sloths aren't exactly the most alert of animals, so if that's your host, you can probably afford to be more obvious about it.
I wonder if dinosaur-era ticks were bigger.
Skipping in order to post that, according to the Buffista Calendar, today is Sean K's birthday.
Happy birthday, Sean! With lots of wishes for a great day and a wonderful year!
Oh, and to anybody who celebrates it, or just enjoys the long weekend we're going to get here in Israel thanks to it, happy shavu'ot!
Happy birthday, Sean.
Had a traumatic dream. Up too soon. Hope it wears off and I can go back to sleep.
In the meanwhile, Don't Stop Believin' from Glee.
Happy shavu'ot, Nilly (and Shir, and anyone else who celebrates it).
Happy birthday, Sean.
General 'has a happy' wishes to everyone else.

I wonder if dinosaur-era ticks were bigger.
The earliest fossil tick dates 90 million years ago (a bird tick, as it happens), so it seems likely dinosaurs didn't have ticks.
What about the tick on the giant sloth?
What about the tick on the giant sloth?
That's an interesting question. The ground sloths weren't anything like as sluggish as their arboreal relatives, so they're likely to have been more fastidious in their grooming; but that's still a lot of animal to watch over. I don't know if we have fossil ticks from ground sloths (or other giant mammals); I still suspect there'd have been selection pressure capping their size, but it's speculation.
Happy Birthday, Sean!
And I love that video for "Don't Stop Believin'"
