sea sausage seaweed
This shiny bulbous seaweed is sometimes seen on our Southern shores,
growing on coral rubble in small, scattered clusters.
Features: Cluster 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. The seaweed is actually made up of tiny branches
packed tightly around a central stalk to form the cylindrical shape,
somewhat like the bristles on a bottlebrush.
According to AlgaeBase,
there are 7 current Bornetella species.
Sometimes confused with 'Taugeh'
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

*Species are difficult
to positively identify without close examination of internal parts.
