I don't know Bob, all the ladies around here seem pretty crabby.

For thousands of years, horseshoe crabs have been coming to the Delaware shore to lay their eggs, which in turn are a great food supply for numerous other species including the endangered red knot.

However, overharvesting of the crabs for their blood (which detects bacterial infections in vaccines) and as bait (because it's cheaper than buying it) has harmed not only the horseshoe populations but those other species (again, like the red knot) which rely on them. Luckily, this year NJ extended and strengthened a ban on horseshoe crab harvesting because of the ecological effects the harvest was having. Delaware has yet to follow suit, but there's still hope.
