Well there's mountain lions, lynx, bobcats, bears, porcupines, raccoons, opossums, and timber rattlers up in maine. All of them could do quite a bit of damage to humans. And the smaller ones are worse...
Of course, none of them will bother people. Except the raccoons

No kidding, I was about to say, are you trying to pass opossums off as dangerous?

I dunno, that one opossum with a jetpack, armour and a sword was pretty kickass. I forget its name now though.

That's disgusting.

Reminds me of those bugs in King Kong.

Wow. I certainly did mis-read that.

Have you ever seen their teeth? They play dead and then they can wake up really quickly, my grandfather had to get surgery in their finger because one bit them.

Those squirrels are EVIL! So my mom would say...We lived on the Maryland side of D.C. and...er yeah...squirrels. It was a windy day and these baby squirrels were all tangled in our chain linked fence, and we took 'em in (well...we took one in, and then a couple of mins. later found another and took it in) and...the first one went raving mad. We uh...put in our bath tub...and...erm..threw lettece at it..I was like 6 when we did this, and my sister and brother were 10-12 years old...so. Yeah. We finally let them out after the storm passed, and they stayed on our front porch...and the psycho one jumped on my mom's head after she came home from work. It was funny to see the squirrel on her head but...I felt sorry for doing it. The other one was very, very timid. The psycho one bullied it a lot. Poor lil' thing.
Anyway, we've got spiders, vicious flies, birds. that sorta thing here. Oh..and thugs! Yeah...there's a group of like 40 people going around beating up people. 40 people to beat one person up...that's insane. So um, yeah. Las Vegas=very dangerous

Texas has 3vil scorpions and spiders. Qatar...has the famous Camel spider...
