This is an incomplete list of notable mutualistic symbiotic relationships, in which different species have a cooperative or mutually dependent relationship. This relationship can be endosymbiotic, whereby an organism resides in another's body or cells.

Some of these relationships are so close that we speak of the composite of two species as one unit; for example, we speak of the composite of algae and fungi as lichens. This is analogous to our speaking of a modulator and a demodulator as a modem.

Endosymbiotic relationships

Symbiosis by luci Endosymbiont Role of endosymbiont Role of host
Euprymna scolopes (Mollusca) Vibrio fischeri Counter-illumination via bioluminescence[1] Reproduction
Legumes Rhizobia Nitrogen-Relationship with the symbiotic host Organic acids (principally as the dicarboxylic acids malate and succinate)
Anglerfish Bioluminescent bacteria Bioluminescent lure for prey capture

Vascular plants mycorrhizae Sequestering of phosphate ions from soil, disease protection Photosynthates
Parasitoid wasps Polydnavirus Immune suppression of parasite host Propagation of the virus
Poaceae (grasses) Endophytic fungi Disease prevention, Drought tolerance[2] Photosynthates

Autotrophic endosymbioses

Host Endosymbiont Role of endosymbiont Role of host
Coral (Cnidaria) Zooxanthellae Photosynthates Protection, inorganic nutrients
Foraminifera (protists) Variety of algae Photosynthates Locomotion, protection, inorganic nutrients
Sponges (Porifera) Variety of algae (Often green-algae) Photosynthates Protection, inorganic nutrients
Hydra viridis (Cnidaria) Chlorella Photosynthates[3] Inorganic nutrients
Elysia viridis (Mollusca) Codium fragile Photosynthates[4] Locomotion, protection, inorganic nutrients
Convoluta roscoffensis (Platyhelminthes, traditionally) Tetraselmis convolutae lopez Locomotion, protection, inorganic nutrients
Pompeii worm Alvinella pompejana (Annelida) Thermophilic chemoautotrophic bacteria Insulation, chemosynthates Locomotion, inorganic nutrients
Mole salamanders Oophila Oxygen (from photosynthesis) Carbon dioxide (from respiration)
Riftia pachyptila (Annelida) Bacteria
Solemya velum (Mollusca) Sulfur-oxidizing chemoautotrophic bacteria[5]
