Sharpeak
Overview
It is difficult to catch since it can bite through fishing lines and chew through nets with ease. It isn't particularly worth the effort, since it doesn't even taste very good. It swims slowly but it has plenty of stamina, moving into freshwater when it's time for it to metamorphose. This Kreature's wild ancestors are found in shallow, coastal waters, where they dig for prey buried in the mud and crunch it up with their powerful jaws.
The simple yet prehistoric look for Sharpeak works well.
