Sea Frost

Aspect:	Clumps of white, irregular calcareous tubes from which protrude the tiny worms' translucent radioles.
Population:	Occasional.
Notable feature:	Can form an entangled encrusting mass or, as seen in one of the picture below, colonise encrusting sponges.
Environment:	Often anchor on mooring shipwreck ropes as seen here, but also colonise sponges and even scraggly black corals as exemplified by two of the pictures below.
Behaviour:	Wary, and abruptly retract into their tubes if approached too closely.
