This feathery green seaweed grows on sand sometimes forming blooms that cover large areas of seagrass meadows on our Northern shores.
Features: A feather-like structure 2-4cm long. The mid-rib or central 'stem' of the feathery structure
is flat and usually with a width wider or the same as the length of
the side 'branches'. The side 'branches' are short, flat and have
rounded tips. These little feathery structures
emerge along the length of a 'stem' that creeps over hard surfaces
or just under the sand.
Colours generally olive green.
Sometimes confused with other
feathery green seaweeds or with seagrasses.
Here's more on how to tell apart different
feathery green seaweeds and how to tell apart feathery
green seaweeds and seagrasses.
