Fiddler Crabs
Wow! The wait is finally over. Our fiddler crabs have arrived. First, we put them in their new habitat. The crabs habitat is made up of salt water and a humus and sand mixture. Next, we fed the crabs plankton and dog pellets. Some of our class observed them eating the dog pellet. Finally, we recorded observations and characteristics that we noticed. For example, we observed that they moved from side to side. We also thought they were exploring their new habitat. All of us are excited to be able to observe them in the weeks to come.

We think fiddler crabs are awesome! We learned that the male has one large claw and one small claw. We can tell if they are right or left handed by which claw is the biggest. We've also observed them digging tunnels. One other thing we've seen is some of our crabs have lost a claw, and a new one is growing.
