Acorn Worm Feces

    Acorn Worm feces piles are a common sight in some sheltered backwaters. The worms live buried in the substrate in U-shaped borrows where they ingest large quantities of sand, digest any plant or animal matter present, and then expel the the remainder. These fecal mounds present a coiled rope appearance. Their common name is derived from their acorn like proboscis.
