Where seen? This fine feathery red seaweed is sometimes seen on our Southern shores, attached to hard things on sandy areas including tubeworm tubes.

Features: Clusters of short feathery 'stems' (2-4cm long). Each 'stem' has side branches covered in fine filaments that result in a feathery appearance. Usually reddish-brown, maroon sometimes with greenish tinge.
