Small parasol green seaweed
Caulerpa racemosa var. peltata*
Family Caulerpaceae
updated Oct 2016

Where seen? This green seaweed with tiny fleshy 'umbrellas' is sometimes seen on our Southern shores. On coral rubble near living reefs, in small clumps.

Features: Forms structures that look like tiny fleshy umbrellas; with a thick circular portion (about 0.5-1cm across) on a little stalk. These little umbrellas emerge along the length of a 'horizontal root' that creeps over the surface. Various shades of green to bluish-green. This is probably a variety of Oval sea grapes (Caulerpa racemosa).

Sometimes confused with similar green seaweeds. Here's more on how to tell apart some green seaweeds.
