sea grapes seaweed
Caulerpa racemosa var turbinata*
seen? This juicy looking seaweed is made up of little bell-shaped
'grapes'. Small clumps sometimes seen on our Southern shores on rocks
and coral rubble near reefs on our Southern shores.
Features: The seaweed resembles
bunches of little bells, with a flattened top. Each bunch about 6-8cm
long, with bell-shaped bead (the 'grapes') arranged on a vertical
'stem'. These bunches of 'grapes' emerge from a long horizontal 'stem'
that creeps over hard surfaces or just under the sand. Colours range
from green to bluish-green.
Sometimes confused with Round
sea grape seaweeds (Caulerpa lentillifera). Here's more
on how to tell apart the sea grapes seaweeds.
