The Ecological & Research Development Group in Milton, Delaware has just developed the world's first life sized female horseshoe crab model. The model is cast in durable resin and is hand painted. It is complete in every detail. The top separates from the bottom to reveal the internal organs, egg distribution and circulatory system. It is a wonderful model to have in a classroom. Below are pictures. If you would be interested in getting one, you should contact Glenn Gauvry.
