Myxicola infundibulum is a type of worm that does not have a common name. The only part of it likely to be seen is the head which is surrounded by a fan of brown or purple tentacles which are joined along most of their length with just the tips free. The tentacles form a funnel shape leading into the head. The body can be up to 20cms long and remains buried in a transparent tube. The worm will rapidly retract the tentacles and shrink its body to about half size if it detects movement close by.
