Codium

/ˈkoʊdiəm/ noun

Definition

A genus of green marine seaweed or algae found in ocean environments, commonly known as dead man's fingers because of its finger-like appearance.

Etymology

From Latin or Greek scientific naming conventions for marine plants; the common name 'dead man's fingers' reflects its dark, decomposed-looking appearance.

Kelly Says

Codium is an invasive species in some regions, spreading where it destroys native seagrass beds—it shows how even 'simple' seaweed can become an ecological problem when introduced to the wrong environment.
