What is this worm?

[Jakepen]

Kind of hard to see, spotted him and a few others in my sand bed. Do you guys have any idea?

Well that video is not clear at all. Look at the light, it's a bit underneath it, and to the right. Very small, black line. Crawls a bit.

It's the black c, extends out to maybe an 8th of an inch.
