Abstract
This research investigates the developmental process of elasmobranch body in order to understand evolutionary mechanisms of benthic body by analyzing the cellular [behavior] of a skate and shark embryos (stages 29 and 30). Understanding this developmental process of Batoidea will allow us to explore and comprehend the evolutionary mechanisms of how skates evolved from sharks, which is a field that has yet to have much research in. The investigation started off with making the sections of shark and skate embryos and scanning them, which we then compared their morphologies in order to identify which tissue is causing their structural difference. We will also create a 3-dimensional reconstruction of each organism by cropping same sized jpegs of each section, which are then compiled together using Amira 3D Software. Using this 3-dimensional model, we will be able to identify differences between the structures of the skate and shark mesoderms. In future investigations, we hope to be able to identify which gene is responsible for the differences.
