Come to think of it, Occamies do resemble dragons in the books, though the design in the film removes the legs. As it's next to India, it would make plenty of sense for it to be an Occamy. As for the Shrake, that appearance would make it look similar to an aligator gar. I admittadly always pictured it as a more typical fish, but a fish based off of a known vicious creature in real life would make sense for a fish specifically created to target Muggle fishing nets.
