Sep 2019
Where
seen? These bright green bubbles are commonly seen on our Southern shores,
growing on coral rubble in small scattered clusters.
Features: Clusters of elongated
bubbles (3-4cm long and about 1cm wide) usually attached to hard surfaces.
The bubbles are sometimes also pear-shaped. Bright green to yellowish
green, the seaweed is smooth and shiny. The skin is thin so the entire
bubble is translucent. Sometimes, 'empty' skins are seen.
According to AlgaeBase,
there are 2 current species: Boergesenia forbesii and Boergesenia
magna.
Sometimes confused with Green
sea sausage seaweed (Bornetella sp.) which is more club-
to cylindrical in shape and is opaque, and Beaded
cushion green seaweed (Valonia sp.) which has tinier bubbles
packed closely together. Here's more on how
to tell apart some green seaweeds. |
