Tree sea fan
Family Melithaeidae*
updated Oct 2016

Where seen? This beautiful sea fan that resembles the silhouette of a large spreading tree is sometimes seen our Northern shores on coral rubble. It also grows on artificial surfaces where it is dark, such as on jetty legs.

Features: 10-15cm tall. A thick sturdy 'trunk' at the base, that branches into increasingly finer stems, resulting in an elegant tree-like shape along one plane. There are swollen nodes at the points where the stems branch. Colours seen include
red, pink or white.

Species in the Family Melithaeidae are difficult to tell apart.
