Baja Centipede + Scorpion under one rock

[many many legs]

I flipped over a rock on a dusty trail found a double venom surprise! I believe this is a Polymorpha pede and an arizona bark scorpion. Any ideas how/when/where to find either of these creatures next time in ensenada without my random dumb luck? Bonus if there's a tarantula under there next time too
ps. what kind of tarantulas can I find near ensenada?

Nice!
