A Theraphosa Blondi Ate My Shoes

All spiders and tarantulas, from tree-dwelling to ground-dwelling, see humans as merely moving ‘land-mass’.
Practically all arachnids have venom, the most potent of which will never be indigenous to the spiders of Great Britain.
The largest of all species, the Goliath Bird Eating spider (Theraphosa blondi) rarely eats birds, actually. But if I were a magpie I’d think “Bloody Nora. I’m out of here”.

Give ’em chance, even the biggest and most ghastly of spiders aren’t out to get us.
Unless they tear your face off.
Sleep tight.
