Over the course of a few days we caught and counted the population of crawdads at Hannah Park. Once we caught the crawdads
they were counted and the left antennae was clipped the first day, on the second day the right antennae was clipped. Many
of the crawdads caught were from 1 to 3 inches in size. The most common crawdad size was 1 1/2 to 2 inches.
What is a Crawdad?
Crawdads are crustaceans that are typically freshwater dwellers. They are usually a reddish brown color and have a thorax
and segmented body. To protect themselves from predators they have pinchers and a hard outer shell. Their pinchers are strong
and also help them capture food. Their food source is fish. They are mainly found under rocks and in rapids. They easily blend
in with the rocks so it's an ideal location for them. The typical size of a crawdad is 10-20cm. Crawdads swim backwards and
use their tails as propellers. Female crawdads also use their tails to carry their eggs. The eggs turn a reddish-orange color
when they are about to hatch. When crawdads are first hatched they are white in color and have a soft shell. Eventually their
shell will develop and they will become less vulnerable.
