Bell sea grapes seaweed
Caulerpa racemosa var turbinata*
Family Caulerpaceae
updated Jan 13

Where 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.

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.
