sea sausage seaweed Bornetella oligospora* Family Dasycladaceae updated Aug 10 Where seen? This shiny bulbous seaweed is sometimes seen on our Southern shores, growing on coral rubble in small, scattered clusters. Features: Clumps of club- to cylindrical shapes (2-3cm long). The ends are blunt, rounded. Sometimes, there are tufts of white filaments at the tips. Shiny, opaque and bright green, sometimes with a brownish or reddish tinge. This seaweed is moderately calcified. According to AlgaeBase, there are 7 current Bornetella species. Sometimes confused with white-stemmed seaweeds (Neomeris sp.) which have white bases to their 'stems' and is more cylindrical (rather than club-shaped). May also be confused with Bubble green seaweed (Borgensenia sp.) which is bubble shaped and translucent. Here's more on how to tell apart some green seaweeds. Bornetella sphaerica forms clusters of oval to round shapes, 1cm or less and found in clusters. Bornetella oligospora and Bornetella nitida form clusters of club shapes (to 5cm tall) that are slightly curved, sometimes with reddish tips. The two species are only positively distinguished by microscopic examination of reproductive features. |
