The green algae division is the largest, insofar as number of species is concerned. It includes 500 genera and 8,000 species: single cell, multi-cell and sometimes multi-nuclear.
Fillamentous algae less than 1 mm thick. A microscope is required to identify various species.
The alga resembles an umbrella or a small mushroom. A central axis and an umbel or disk are evident at the top. The top is made of a number of rays,
A flattened alga that resembles a green fleshy ‘leaf’. It is thicker and harder than the ‘leaf’ of an Ulva and easier to break than to fold. The edge of the thallus is somewhat curled upwards. The gen
The alga resembles a bundle of thin, green strands. A microscope is required to identify the genus and its species, at which point the dichotomous (two-horned) branching that characterizes the Boodleo
The algal branches are green and very soft, and they gently sway with the water current. When the thallus unfurls in the water, the algal structure is revealed
The Caulerpa mexicana resembles the Caulerpa scalpelliformis but is more delicate. The indentations between the lobes are deeper and create the appearance of a compound leaf.
The thallus is flat and has no indentations, as do other Caulerpa species in this region. The Caulerpa prolifera’s branches resemble an elongated ‘leaf’ whose sides and edge are rounded.
The Caulerpa racemosa resembles a bunch of small green grapes. The ‘stalk’ is horizontal, and sprouts erect branches, upon which short branches hold globular, sometimes slightly elongated ‘leaves’.
The Caulerpa scalpelliformis thallus resembles flat, emarginate ‘leaves’ that are uniformly separated by indentations into lobes. The indentation depth reaches a third of the thallus width.
The Chaetomorpha resembles a cluster of green filaments. A microscope is needed to identify the genus and the species. The Chaetomorpha has one long row of cells, but no secondary branching, unlike th
A green, filamentous alga, its filament is comprised of one row of cells. Through a microscope, branch-like divisions are evident the entire length of the filament. The branching points in the same di
The Cladophora pseudopellucida resembles a small, dark green bush. Its branches are multi-branched, either dichotomously or trichotomously.
The Cladophoropsis resembles light green, compact cushions and is common in the wave-breaking region. The cushions are made of a dense mass of thin, branched ‘stalks’.
The Codium decorticatum resembles the Codium vermilara but is structurally more delicate. Its dichotomous branches are thin and cylindrical;
