What is this tube in my sandbed?

Does anyone know what this is it's about 2cm long and it sticks out the sand and looks like it has sand all over it it also has 2 like whiskers on the end. It's not a worm looks more like some sort of coral

Looks like a tube worm to me. Harmless hitch hiker that builds a tube using the substrate.
