okay.. here's one which looks like a horrific experiment on
cross breeding your worst nightmares gone bad... just imagine a
scorpion and a giant spider bred...
the result would be a Whip Scorpion

it looks horrifically like a spider with pincers... or a long
legged scorpion with no tail..
although it is an arachnid, it is neither a spider nor a
scorpion.. called a whip scorpion because it usually has (but not
always) a long whip-like tail...
it hunts insects and worms (and your dreams) with its
pincer-like front arms....
