Enough visibility to see the massive crabs

I feel like I'm on a roll here with all the 'dangers' lurking in the ocean. For the longest time I've been wearing booties - I started wearing them after regularly being pinched by crabs. I've been weaning myself off my booties for the last few weeks...but after today I am not so sure... The water was heavenly, another day with no waves, no wind, fantastic visibility - one one could see every little shell. This fantastic visibility meant that one could also see the MASSIVE crabs...and suddenly I feel like I need to rethink the booties...
