The size of an animal is a very important physical trait that often plays a key role in many aspects of its life. It is common to see the larger an animal is, the better suited they are to survive adverse conditions in their environment including predators. This study was conducted as a new study that was testing two variables regarding the distribution of C. Carinirostris to hopefully find if there is a correlation between the two. I collected 15 crayfish from each of the 3 different habitat types, these habitats are defined in the paper below, for a total of 45 crayfish from different parts of one stream to see the relationship between habitat type and body size. The crayfish were caught in the stream with a handheld net and then organized by the surrounding habitat in the area they were caught in before being measured on shore. The results of the experiment were very encouraging as I saw the statistical analysis calculation support my tested hypothesis and the correlation between habitat type and body size was proven.
