Hammerhead Shark

When I was young, decades ago, I read this book about some scientist who was studying volcanic activity and how the vortex attracted multitudes of sharks especially hammerheads. Id never seen one.. not even in an aquarium back then.. and since then I've had this awe mixed fascination for them..

I was wandering about at darling harbor today and saw these marvelous photos of phosphorescent deep sea creatures which brought all the images of hammerheads back...  I just had to try and draw one!
