The claws are used for digging, or as defense. As you will see in our journal we did find a crawdad with one claw and released him back into the creek. Crayfish are hunted by otters, raccoons, minks, snakes, turtles, fish, and certain birds. Crawdad can also go into reverse if they are attacked. They eat snails, small fish, tadpoles, or young insects.
Crawdads come in different colors, from blue and green to red and brown.
The only color crawdads that we saw in the creek were red and brownish colored. The clear white crayfish is a blind animal that lives in underground railroads. Crawdads mate in the autumn, the female crawdads produce about a hundred eggs or more. Since, we did our project during the fall, it may have some affect on the data, if you did this same experiment in the winter, spring or summer, you may find more or less and the results from the different tests may be different then our data. We were going to answer our question with the different tests listed in the introduction.
