Hello. There are multiple types of sharks in the bay. The bigger ones are called Leopard sharks. These are a beautiful fish with spots like a leoaprd, hence the name. A couple others are smooth hound sharks and sand sharks. Those are the ones I have caught in Newport Harbor. Just outside of the jeddy you will be able to find Mako's, blue sharks, and rarley a great white. Catalina see's more whites in this area then any other close to Newport Beach. Hope this helps.
