Info

Caulerpa cactoides (Turner) C.Agardh, 1817

Caulerpa is a genus of seaweeds in the family Caulerpaceae (among the green algae). They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world. A species in the Mediterranean can have a stolon more than 3 m long, with up to 200 fronds. This species can be invasive from time to time.

The Cactus Caulerpa Caulerpa cactoides is found along the coast region of Western Australia.
