A couple of days ago at the boat ramp for Cocoa Beach, I spotted a
copulating couple of horseshoe crabs skittering in the shallows. I looked
closely and found that there were four sharp-ribbed drills (Eupleura
caudata) perched on the female's dorsum.
What were those drills up to?
This question has me alternately searching for a serious answer or a perfect
punchline.
