Nageri
The Nageri are a race of space-dwelling aliens.
An adult Nageri has, on the average, a mass of about 500,000 metric tons. The race naturally has the ability to manipulate subspace fields, thus they can travel at warp velocities without the aid of artificial technology.
These massive creatures inhabit space and are in many respects similar to Earth whales. The Nageri 'feed' off of pure solar energy, and use this energy to generate the chemical components that their bodies need to survive (in a process similar in many respects to photosynthesis). The Nageri gather the raw chemical material they need by 'eating' comets and other space debris.
Due to their ability to manipulate subspace fields, these creature communicate using a natural form of subspace radio communication.
Their dense hides are at least as strong as the tritanium/duranium hulls used on most Federation starships. This makes them invulnerable to the temperature and pressures extremes of space.
Socially, the Nageri are again similar to whales, traveling in groups called pods, and have a high level of social organization. While they are intelligent, they are not able to produce technology due to the fact that they lack limbs that are capable of the required manipulation.
Not much is known about this race of sentient ships. All that is really known is they form symbiotic relationships with their crewmembers (something like Gomtuu, in TNG). They are telepathic to a point, and follow mental or verbal commands
They live in fear of the Xenolithe, who hunt and subdue them without mercy.
