[4] It is not to be confused with a closely related species, Urechis caupo, which occurs on the western coast of North America and shares common names.

This spoonworm is a detritivore, feeding on detritus and lives and burrows in sand and mud like other Urechis species.

The worm draws water through its burrow by peristaltic contractions of its body and food particles adhere to the net.

[7] In Korea, it is called Gaebul (Korean: 개불), which means a dog's testicle or penis.

In Chinese cuisine, the worm is stir-fried with vegetables, or dried and powdered to be used as an umami enhancer.
