The green “Signal” crawfish is the rarest species of crawfish in North America. They cook up red like their cousins, but are much larger than the red swamp variety. Like many crustaceans, “Signal” crawfish are either left or right claw dominant. In this species, there is a tiny white dot between the claws on the dominant side. In repose, these critters go into a kind of trance, and as their claws open and close reflexively, this tiny white dot appears and disappears and then reappears. Famous abroad, especially in Sweden,these massive crawfish are sure to delight and amaze, and can be shipped LIVE to any kitchen in America.
