| Bubble
green seaweed Boergesenia forbesii* Family Siphonocladaceae updated Dec 08 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. |
