Ophthalmosaurus is the tropical cousin of Ichthyosaurus, it is well known among sailors for being a life saver for marooned men, as the Ophthalmosaurus will sometimes share food with people it feels are starving, which normally is stuff like the heads of fish it doesn't swallow or a crab it picked up. Most people just appreciate the generosity.
