Acetabularia acetabulum is a unique, solitary seaweed species found primarily in the Mediterranean Sea. This green algae is notable as a long-lived, single-celled organism that has been extensively studied by biologists. Its simple structure and readily observable cytoplasmic processes make it an im...
Caulerpa taxifolia is a species of green algae belonging to the Chlorophyta group. It’s notable for its rapid growth and aggressive spread when introduced into new environments, particularly becoming an invasive problem in coastal ecosystems like the Mediterranean Sea. Originally cultivated as an aq...
Valonia ventricosa is a tropical green alga notable as one of the largest known single-celled organisms, with glossy spherical cells reaching up to 5 cm in diameter.
Caulerpa racemosa is a pantropical green alga that invaded the Mediterranean from the 1990s onward, outcompeting native seagrasses and algae across vast seafloor areas.
*Caulerpa lentillifera*, or sea grapes, is a green alga farmed extensively in the Philippines for its edible, caviar-like texture in raw coastal salads.
Halimeda tuna is a calcified segmented green alga of the Mediterranean and tropical Atlantic, contributing significantly to carbonate sediment accumulation in reef ecosystems.
Ventricaria ventricosa is the currently accepted reclassification of the large-celled tropical alga formerly called Valonia ventricosa, recognized as one of Earth's largest single cells.
Codium fragile is a spongy green alga native to the Pacific that has invaded Atlantic and Mediterranean coasts, widely known as 'dead man's fingers' for its branching thalli.
Halimeda opuntia is a pantropical calcified green alga and a major contributor to carbonate sediment production on coral reefs throughout the Indo-Pacific and Caribbean.
A green alga notorious for forming massive green tides, including a record-breaking bloom spanning thousands of square kilometers off Qingdao, China, in the summer of 2008.
Caulerpa serrulata is a tropical green alga of the Indo-Pacific and Red Sea, distinguished by its flattened, serrated fronds growing on sandy or rocky substrates.
Penicillus capitatus is a calcified green alga of tropical and subtropical seas nicknamed 'merman's shaving brush' for its tuft-like head, and a notable carbonate sediment producer.
Udotea flabellum is a calcified fan-shaped green alga of tropical and subtropical seas, contributing to carbonate sediment production in seagrass beds and sandy reef areas.
Codium tomentosum is a dark green, spongy alga native to European Atlantic and Mediterranean coasts, with a dichotomously branched thallus reaching up to 30 cm in length.
Caulerpa cupressoides is a tropical green alga native to the Indo-Pacific and Caribbean, recognized by cylindrical branchlets resembling the foliage of cypress trees.
Bryopsis plumosa is a delicate feathery green alga of temperate and subtropical rocky shores, forming plume-like fronds in shaded intertidal and subtidal pools.
Udotea cyathiformis is a calcified green alga of the tropical Atlantic and Caribbean, distinguished by its funnel-shaped thallus anchored in sandy subtidal substrates.
Chaetomorpha linum is an unbranched filamentous green alga of sheltered lagoons and estuaries globally, often forming loose, unattached mats in nutrient-rich shallow waters.
A green alga of cool temperate North Atlantic and North Pacific waters, forming single-cell-thick translucent sheets and commercially used as a food ingredient in Japan.
Dictyosphaeria cavernosa is a tropical green alga forming hollow, bubble-like colonies on coral reefs, used as a bioindicator of eutrophication and reef degradation.
Cladophora glomerata is a filamentous green alga notorious for forming dense nuisance blooms in eutrophic freshwater and brackish coastal ecosystems worldwide.
Avrainvillea nigricans is a dark, spongy green alga found in tropical and subtropical seas, typically growing on sandy or muddy substrates in sheltered lagoons and reef flats.
A cosmopolitan green alga, reclassified from Enteromorpha intestinalis into Ulva, highly tolerant of low salinity and prone to blooming in nutrient-enriched estuarine waters worldwide.
*Ulva lactuca*, or sea lettuce, is a widespread green macroalga notable for forming massive, disruptive green tides in coastal waters with high nutrient pollution.
Bryopsis hypnoides is a small, moss-like filamentous green alga found in sheltered intertidal and subtidal zones of temperate seas, forming soft tufts on rocky substrates.
Codium adhaerens is a Mediterranean and eastern Atlantic green alga forming flat, encrusting thalli tightly adhered to rock in intertidal and shallow subtidal zones.
Cladophora rupestris is a dark green filamentous alga common on shaded rocky shores of the North Atlantic, persisting year-round in intertidal crevices and pools.
Chaetomorpha antennina is a stiff, unbranched filamentous green alga common on tropical and subtropical rocky intertidal shores, attaching to rock via a basal holdfast.
A dark green alga of cold North Atlantic and North Pacific waters, notable for producing dimethylsulfoniopropionate (DMSP) and forming dense mats that suppress underlying benthic communities.
Siphonocladus tropicus is a tropical green alga of the Caribbean and Indo-Pacific, forming branched, tubular thalli on rocky intertidal and shallow subtidal substrates.
