Integral Trees, The
This story is set in an incredibly exotic environment, the gaseous envelope of a binary star system in which one of the pair is a neutron star. The bizarre life forms which populate the Smoke Ring, as it is termed, are a tour de force of imagination for Niven.
Perhaps the most fascinating aspect of the story is the way that the suvivors of a lost colony ship and their descendants evolved a new physiology to help them exist in the low gravity environment of the Smoke Ring and their symbiosis with the Integral Trees themselves.
