Huge Oak Leaf - is this a named Croton?

[Jeff in Costa Rica]

Some friends of mine from PA are visiting right now. They rented a house located down the beach from me and I got a chance to see the garden for the first time today. As we were walking down the trail to the beach, I noticed this Croton with the largest Oak Leaf shaped leaves I have ever seen. My friend Henry stuck his hand in the photo for scale. Is this normal? Almost every leaf on the plant was this size. I would love to get a cutting.

Sorry, I realized afterwards that I didn't get a shot of the entire plant.
First photo is with a flash, second photo is without a flash.
