Tree
sea fan
Family Melithaeidae*
updated
Dec 2019
Where
seen? This beautiful sea fan that resembles the silhouette
of a large spreading tree is sometimes seen our Northern and Southern 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. |
*Species
are difficult to positively identify without close examination.
On this website, they are grouped by external
features for convenience of display.
