I was fishing a few weeks ago and on the beach at night were these little crabs about 2" long. They were whitish and moved with lightning speed. I thought about using them for bait but there was no way I could catch them. Tried for about 5 minutes and gave up. Someone in a tackle shop told me they are called ghost crabs. Does anyone know more about them and have you ever seen them out there at night? Or was I imagining things, lol?
