Rama Revealed

The myrmicats (named by Richard Wakefield, a combination of the Greek word for ant, myrmex, due to their ant-like appearance, and the English word "cat" due to their feline size and running gait) were a naturally heteromorphic species whose final form was a large, interconnected sentient mesh which was able to directly interface with the human brain through a network of fibers connected to the body; while entering a symbiosis with another sentient "avian" species.

Through this medium, it was able to communicate to Richard the threat posed to the species by the violent colonists, and at the request of the myrmicats he leaves their habitat carrying some of their eggs for preservation.

After the human colony leader starts bombing the octospider city under a made-up pretext and the octospiders retaliate, the situation becomes dire enough that Rama's controlling intelligence intervenes to end the conflict caused by the humans aboard, by sending everybody into hibernation until the end of the journey, except for the surviving myrmicats which are allowed to lead their daily life.

The Rama spacecraft rendezvous with another Node, an enormous tetrahedron near the star Tau Ceti, designed to research any intelligent life capable of spaceflight.
