Spionid worm

This interesting critter is found in most reef tanks near the rockwork or in the substrate of the refugium. The worm (possibly a Chaetopterid or Spionid) secretes a mucous to build a small tube with sand grains (two tubes visible in this image), and extends two 'palps' for feeding. The worm itself is very small (1/10" to 1/4") but its tentacles can be up to 10 times longer than its body. Chaetopterid is pronounced "key-top-terid." Reef-safe
