Welcome to the collection of images dedicated to the diverse types of algae — essential inhabitants of aquatic environments across the planet. If you need quality photographs of algae for study, illustrations, or inspiration, you will find a wide range of images covering both microscopic and large forms.

Algae represent a diverse group of organisms predominantly living in freshwater and saltwater, although many species can be found on moist soil, rocks, or trees. In our collection, you can encounter images of marine and freshwater algae of various types — from unicellular microalgae (phytoplankton) to large multicellular forms that sometimes resemble thin plants but belong to a separate kingdom. The physical characteristics of algae range from delicate transparent filamentous structures to dense and massive layers that form entire underwater "forests."

Often in photographs of algae, you can see various types encircling their aquatic ecosystems: marine shorelines, rocky areas, sandy bottoms of lakes and rivers, sometimes growing on stones or surfaces of shells and corals. This can be a mix of different taxa — green, red, and brown algae, each occupying its niche and playing a crucial role in the biogeocenosis.

The images of algae often demonstrate their structure: characteristic layers, branching, leaf-like or filamentous forms, as well as growth and reproduction processes. At different times of the year and under various conditions, you may notice changes in their density and color, reflecting development cycles and adaptation to the environment — from the icy freshness of coastal waters to warm tropical seas.

The collection also includes photos of marine ecosystems where algae serve as a source of food and shelter for many marine inhabitants — fish, mollusks, and crustaceans. Algae form an important part of biological and climatic processes, participating in oxygen production and carbon dioxide absorption, underscoring their significance for the entire planet.
