fan green seaweed Udotea sp.* Family Udoteaceae updated Jan 13 Where seen? This fan-shaped seaweed is sometimes seen at Tuas, growing on and among coral rubble. Elsewhere also in sand. Features: A long fan- or spatula-shaped blade (2-4cm long) with ruffled edges, in clusters of several blades. Sometimes really long ones (about 10cm) are seen growing in clumps of a few large blades. The blade is made up of a tangle of tiny filaments that give it a velvety texture and is slightly to moderately calcified. The stem that holds up the blade (stipe) is calcified. Usually olive green, but may be bright to dark green. According to AlgaeBase, there are 40 current Udotea species. Sometimes confused with other fan-shaped green seaweeds. Here's more on how to tell apart fan-shaped green seaweeds. Human uses: Some species have anti-bacterial and anti-tumor properties. |
