Sand grains from Maui, Hawaii. These were the first grains of sand that I examined through the microscope. I was amazed by the array of spectacular bits and pieces. The "Y" shaped glassy structure at the top is a sponge spicule, which functions as the internal skeleton of most sponges. Just to the left and down are two perfectly formed microscopic shells. Just to the right and down from the sponge spicule is a bit of brown sea urchin spine, with its intricate structural design
