Transcript of fiddler crabs

Fiddler Crabs hide in the sand because they need protection and they are scared.
Observations
More Observations
Once my group found out that Fiddler crabs hide in the sand for protection, we wanted to do a experiment. We did a experiment where we would shine a flashlight on them to see how they would react. First, we turned off the lights, turned on the flashlight, and shined the light on them. We thought that they would go into the homes that they made but they didn't, except for one. Wanda [ Maxine's crab] didn't like the light but the rest of them did. The rest of them stayed right where they were. We called it "Enjoying the Spotlight!"
Did you know?
Fiddler crabs are always doing something. Its rather running, eating, or digging holes. So if their always doing these things that means that they must be good at it.
Hypothesis
We think that Fiddler Crabs hide in the sand for protection and to hide from predators.

Why do Fiddler Crabs hide in the sand?
Research

On our #5 observation we found that the female Fiddler crabs had made homes in the sand over night. They stayed there until we changed the
water because
they made 5
homes for 4
crabs close to
the water.
Our group researched why fiddler crabs hide in the sand because we were very interested in why they do this and they are mostly always in the sand. We found out that they do this because they think that we are trying to hurt them.
