Watch out for wandering crayfish!

This short video shot near Chicago was posted a few weeks ago on youtube, and it shows the remarkable ability of crayfish to traverse land in search of a new aquatic home. It's no wonder that crayfish are among the most successful aquatic invasive species in many parts of the world - their ability to invade new habitats by traversing through grasslands, fields and or other terrestrial areas makes them an ideal candidate for invasion. Can you imagine if all aquatic invaders had such an ability??!
