Robbie's Guest book comment

Robbie saw a red ball in the tank that looked like blood. It didn't seem likely that it came from the crab since club members noted that horseshoe crab blood is blue. At the Science Club, we looked at it under the microscope. Some people thought it looked like a piece of shrimp. Some people though that it looked like a dead crab egg. So, at the end of the meeting, we weren't sure.

However, on Monday, when Sam and Sadie were feeding the crabs, their mom noticed that one of the shrimp seemed to have a red ball in its middle. Do you think this might be the answer?

Apparently, that is the egg sac.

We will try to get a photograph of the red ball.
