Ghost

Some days you just want to sit on a beach and shoot video of ghost crabs.

For roughly my whole life I’ve wondered why white-sand beaches only have white crabs and black-sand beaches only have black crabs. I figured that every beach started out with all colors of crabs and the seagulls sorted things out… But, get this:

When the black-sand specimens were subsequently exposed to a white background, they were observed to gradually become lighter over the course of about a month. The opposite happened to white-sand specimens when placed in black backgrounds.
