Shark Egg Case Project

Sharks are a very important component of marine ecosystems. Many are top predators regulating the numbers of other species. Sharks tend to feed off old, sick and slow prey keeping prey populations healthy and population numbers optimum preventing ecosystem damage by, for example, over grazing.
There are a variety of sharks (approximately 25% of all sharks) that are friendly, easy to handle and reproduce by shedding eggs. The Whale Coast Conservation project focusses on these. This reproductive type is called ovipary. Eggs have different shapes, sizes and colours just like one finds amongst different bird species.
