Green Alga

Codium pomoides


Amazingly made up of just one cell, this dark green alga was globular, firm with a suede-like surface and about 60 mm in diameter. There were a few on the shore and some were hollow.


Seen along the high tide mark with other sea weed - Westernport Bay


These grow attached to underwater rocky reefs by rhizoids. They are seen to a depth of 20 mts. They are self repairing and under water, appear to have a fluffy appearance with long filaments on the surface of the globe.
Family: Codiaceae

The fact that it is made up of only one cell is amazing!

You're welcome Leuba. The thanks go to you for continuing to document here many of the less well known groups of organisms, showing not only diversity in species, but diversity in biological structure as well!

Congratulations Leuba, your green alga is our Spotting of the Day:

"This green alga (Codium pomoides) may be 60 mm in diameter, but it is actually made up of one single cell! Green algae in the order Bryopsidales are what is known in biology as coenocytes (from the Greek: κοινός (koinós) = "common" + κύτος (kýtos) = "box, i.e. cell"). In these algae, multiple cell nuclei, chloroplasts and other organelles are packed without separation within one cell wall, and can freely move throughout the whole organism".
