Microscopic Animals - The Horseshoe Crab

Ms. Medina isa grad student from Florida Institute of Technology. She is studying marine biology or science. She has been studying horseshoe crabs for the last two and a half years.

Ms. Medina visited with and taught the third grade class and fifth grade class all about horseshoe crabs.

This pod cast is the third grade class telling what they learned. Mrs. Robb was kind enough to allow us to use this video.

   
Lauren took videos of the horseshoe crab her fifth grade class was looking at. Ms. Medina was visiting the classroom to teach everyone about the horseshoe crabs.

The horseshoe crab is related to spiders rather than crabs! They look dangerous, but they are not. These samples are microscopic, but the horseshoe crab can grow to be about 3 feet!

The crabs use their eyes to find a mate! Their tails are not used as a weapon, but as a rudder to move the crab and help it tip itself over if it needs to.

Learn more about the horseshoe crab by watching the videos and pod casts!
