Before they are cooked to bright-red perfection, crawfish can be blue, green, white or yellow. Crawfish walk forward and swim backward because they have four legs for walking and four for swimming.Click to see full answer. Also asked, do crayfish move backwards? Common name: Crayfish Their four pairs of walking legs assist them in rapid locomotion across the bottom substrates of their aquatic habitats. Surprisingly, they are not really capable of swimming although they can use powerful thrusts of their tails to rapidly propel themselves (backwards) through the water.Subsequently, question is, how do crayfish move? Crayfish swim by beating pairs of paddles called swimmerets on each body segment. The swimmerets move in sequence, starting at the back of the animal and moving forward. The movements of each segment keep a precise difference in timing, while varying in speed and force. Furthermore, how does the crayfish swim rapidly backwards? Large muscles in the abdomen curl the tail fan forward beneath the body propelling the crayfish rapidly backwards. Typically crayfish walk slowly forward on their legs, but if they are startled, crayfish use rapid flips of their tails to quickly swim backwards in a series of jerking movements to escape danger.Why do crayfish leave the water?The location of their gills under the carapace means that they stay moist for some time even when the crayfish is out of the water. This and the crayfish’s ability to tolerate low oxygen levels allows them to venture from the water for short periods.
