what is a crawdad bird

A crawdad is another word for crayfish, a type of freshwater crustacean that looks like a miniaturized lobster. They have five pairs of legs, or 10 legs total, with the front two legs modified into large claws, called chelae, used for defending themselves and snagging food. Crawdads can make noise, which sounds a bit like Morse code, using a thin appendage that draws water and air through the gills. The noises made are likely used for communicating with other crawdads and to alert others to the presence of predators. Crawdads are a keystone species, meaning they are integral to the overall health of their environment, as they are a food source for numerous animals in their ecosystems, including raccoons, foxes, snakes, turtles, fish, and waterbirds.
