Chloroplasts probably evolved following an endosymbiotic event between an ancestral, photosynthetic cyanobacterium and an early eukaryotic phagotroph. [17] This event (termed primary endosymbiosis) is at the origin of the red and green algae (including the land plants or Embryophytes which emerged within them) and the glaucophytes, which together make up the oldest evolutionary lineages of ...

Marine botany is the study of flowering vascular plant species and marine algae that live in shallow seawater of the open ocean and the littoral zone, along shorelines of the intertidal zone, coastal wetlands, and low-salinity brackish water of estuaries.
The characteristics of the Posidonia plant, its growth dynamics and the large amount of biomass produced, are factors that can sustain very diverse plant and animal communities. Distinguished are: epiphytic communities (that is, bacteria, algae and bryozoa that colonise the surface of the leaves and rhizomes of the plant), vagile and sessile ...
Also known as Red berries as well as Red grape caulerpa despite not belonging in the Caulerpa genus.

The sea cucumber, like other bioluminescent animals, is able to emit light. It uses this effect as an alarm to expose its self and potential predators in times of an attack.
Seaweed occupies various ecological niches. At the surface, they are only wetted by the tops of sea spray, while some species may attach to a substrate several meters deep. In some areas, littoral seaweed colonies can extend miles out to sea. [citation needed] The deepest living seaweed are some species of red algae.
The national Red List is compiled and maintained by the Ministry of the Environment, alongside a separate Red List for marine organisms. Similarly drawing on the relevant scientific authorities, NGOs, and local governments, the Ministry of the Environment also prepares and publishes a Red Data Book ( レッドドデータブック , reddo dēta ...
