Transcript of Adaptation of Crayfish

Adaptation of Crayfish
The Eyes and Pincers
The eyes of the crayfish are adapted so that they can see in the silt filled water of the streams, in which they live.\

Pincers are the claws used to protect themselves as well as obtain food and other sources needed to survive. The large pincers grab and hold prey, and they help ward off predators.
These are adapted to help the animal sense movement the water, and also a chemical change. A chemical change could indicate many things, like dead fish or even potential mates.
Crayfish females have developed a way to keep their eggs safe. Their eggs are usually fertilized in February, however, the females can carry these eggs for multiple months before laying them to help keep their babies safe.
In Conclusion
. . .crayfish have gone through multiple adaptations throughout the many millions of years that the earth has existed.
The crayfish is a dull reddish color in order to fully reflect their environment. They would be dark brown if they wanted to blend in with rocks and soil and so forth. They molt several times a year as they're growing, then periodically as adults.
