A few weeks ago, on one of my beach explorations I found these devil's purses washed up on the high tide line. Egg cases like these are found worldwide and come from skates, rays and some sharks and are also known as 'mermaid's purses'.
They vary in size and colour, these being fairly large. By the time they are washed up, the embryos are usually long gone from their casing into the open sea. I was given a link to an egg casing identification site and by comparing size, shape and colour have determined that the casings that I have likely come from Undulate Rays.
Rays and skates belong the shark family and are common in waters around the world.
I had the casing in front of me in the car and the only paper to hand was the back of a large brown envelopeso this is the resulting sketch. I'm currently working on various sketches and compositions with these for a larger drawing or painting.
