• The first stage in many forms of bloodworm is a zooplanktonic stage followed by the benthic instar where the familiar segmented red larvae develop protected by silk tubes made in the bottom silt.
• It is suggested that its dominant feeding mode is searching for zooplanktonic prey ( copepods in particular ) using bioluminescence to illuminate a small search area, with infrequent encounters with larger prey items.
• In bays where they occur in very high numbers, predation by ctenophores may control the populations of small zooplanktonic organisms such as copepods, which might otherwise wipe out the phytoplankton ( planktonic plants ), which are a vital part of marine food chains.
