Symbiosis

From Memory Alpha, the free Star Trek reference.

For the TNG episode of the same name, see "Symbiosis".

Symbiosis is a dependent relationship between dissimilar organisms. Types of symbiosis include parasitism, mutualism, and commensalism. Although some would argue that "symbiosis" only refers to mutualism.

[edit] Parasitism

The relationship is harmful to one, but beneficial to the other. Unlike normal predatory behavior, it is usually in the parasite's best interest to keep its prey alive. The parasite also lives very close to, or attached to the victim.

• Anaphasic lifeform
• Ceti eel
• Denaxian tapeworm
• Interspatial parasite
• Onaya, although this might be considered mutualism on some level
• Redjac
• Tarchannen III species
• Ves Alkar

• Neural parasite (23rd century)
• Neural parasite (24th century)

• Silicon-based parasite

[edit] Mutualism

The relationship is mutually beneficial to both organisms.
