"Alga marina" is a phrase used to refer to a type of marine plant or seaweed. Its spelling is based on the Latin roots for "seaweed" and "marine", respectively. The first word, "alga", is pronounced /ˈælɡə/, with the emphasis on the first syllable and the "g" sound coming from the back of the throat. The second word, "marina", is pronounced /məˈriːnə/, with the emphasis on the second syllable and the "r" sound being rolled or trilled.

Alga marina is a Spanish term that translates to "marine seaweed" in English. It refers to a broad category of aquatic plants that predominantly inhabit saltwater environments such as oceans and seas. Alga marina can also be commonly known as seaweed or marine algae.
These organisms represent a diverse group of photosynthetic, multicellular organisms that lack roots, stems, or leaves like traditional land plants. They are classified within the kingdom Protista and encompass a vast variety of species, ranging from small, simple organisms to large, complex forms.
Alga marina plays a crucial role in marine ecosystems, serving as primary producers. Through photosynthesis, these organisms convert sunlight, water, and carbon dioxide into organic compounds, releasing oxygen into the water as a byproduct. This process provides an essential source of food and energy for marine organisms, including fish, invertebrates, and even mammals.
Furthermore, alga marina offers a variety of commercial and industrial applications. Some species are harvested for use in human consumption, serving as a source of minerals, vitamins, and dietary fiber. Others are utilized to produce various products, including fertilizers, cosmetics, and pharmaceuticals.
Overall, alga marina represents a diverse group of marine seaweeds, contributing to the health of marine ecosystems, and offering numerous commercial applications due to their nutritional and chemical properties.
