Best Crustose
Porolithon onkodes is a species of crustose coralline red alga prevalent across Indo-Pacific coral reefs. It functions as a primary reef-building organism by depositing calcium carbonate, which helps cement reef rubble together. This algal species often dominates exposed reef crests, forming durable...
Clathromorphum circumscriptum is a species of crustose coralline red algae found in cold-water marine environments, particularly in the Arctic and subarctic regions. It grows by depositing annual layers of calcium carbonate, creating a hardened skeleton that can persist for centuries. Because these...
Phymatolithon calcareum is a species of crustose coralline red algae found in the northeast Atlantic Ocean. This marine plant plays a crucial ecological role by forming free-living structures known as maerl beds. These slow-growing, calcified habitats provide a vital substrate and refuge for a wide...
Crustose coralline red alga of the northeast Atlantic and Mediterranean, co-forming maerl beds with Phymatolithon calcareum and historically harvested as a calcareous soil amendment.
Red alga (Peyssonneliaceae) widespread in the Mediterranean and Atlantic, forming scale-like encrusting thalli on shaded and deep rocky reef surfaces.
Ralfsia verrucosa is a crustose brown alga (Ralfsiaceae) forming dark-brown patches on intertidal rocks worldwide, one of the most common encrusting brown algae in temperate seas.
Crustose coralline red alga found in the Mediterranean and eastern Atlantic, capable of growing as both attached crusts and free-living nodules that structurally resemble maerl.
Lobophora papenfussii is a brown alga (Dictyotaceae) named after phycologist George F. Papenfuss, forming lobed, fan-shaped thalli in tropical and subtropical marine environments.
Codium adhaerens is a Mediterranean and eastern Atlantic green alga forming flat, encrusting thalli tightly adhered to rock in intertidal and shallow subtidal zones.
Encrusting coralline red alga widespread on North Atlantic and Mediterranean rocky substrates, forming prominent pink-purple crusts and contributing significantly to biogenic calcium carbonate.
Titanoderma pustulatum is a crustose coralline red alga widespread in temperate seas, known for inducing larval settlement of marine invertebrates on rocky substrates.
Thin crustose coralline red alga found in temperate seas worldwide, typically growing as an epiphyte directly on the blades of seagrasses and larger macroalgae.
Cosmopolitan brown alga of tropical and subtropical reefs, studied for allelopathic effects that inhibit coral recruitment and contribute to phase shifts on degraded reefs.
Thin crustose red alga found on rocky marine and estuarine shores across temperate regions, forming dark blood-red patches that adhere tightly and smoothly to rock surfaces.
A crustose coralline red alga forming calcified crusts on tropical and subtropical Indo-Pacific reefs, contributing materially to reef consolidation and substrate stabilization.
