This week in science I dissected a Crawfish. These two pictures above show a Crawfish. The first picture shows the head view of the Crawfish. They use their antenna as their second eyes. This feature helps them feel vibrations in their environment. The proximal of the antenna connects at the head. The Distal is the end of the antenna. This adaption allows them to get away from predators and help them survive . The dorsal view of the craw fish displays all the antennas and eyes. The ventral view displays the Crawfish's abdomen , where the body segments are.
This week in science I learned a lot of interesting things. While dissecting , I learned that the liver of a Crawfish is yellow/orange color . One question that I have is, how does a Craw fish find food if it doesn't have its antenna ? Also, do Crawfish have good eye sight ? I can also make a connection with my animal , because earlier on the year we did a project where our animals had to adapt to an environment . This is similar because i learned that a Craw fish uses its antenna to feel around it environment , and this is a perfect example of animals adapting to their environment.
