Jotoki resemble large,
spindly starfish. They have a torochord (ring-shaped) instead of a
notochord, with five "self-sections" (apparently semi-independent brains) that operate the Jotok's body cooperatively. The Jotoki begin life as small aquatic swimmers, most of which are eaten by predators; in time, five of the survivors will merge to form one collective organism, which grows into an
arboreal adolescent form; its tails become arms, and its fins differentiate into fingers. When it grows large enough, the Jotok
imprints itself on an adult (if one is available) and enters a stage of rapid learning and brain growth. A Jotok who desires a family can simply go into the wilderness and "harvest" an adolescent of the proper age (a property that Kzin slavers later exploit). Unimprinted adult Jotoki are considered
feral, and regarded as little more than animals. Since the five subunits that make up one Jotok individual are not necessarily genetically related, reproduction does not require sex; a Jotok can simply find a pond and deposit its offspring to begin the cycle again. Before their enslavement, Jotoki operated in groups called "clanpods", as part of their former planet-wide tradeweb. Details of this arrangement are not known. Jotok technological specialties included gravity polarizers, linguistics and biotechnology. They had the ability to force-grow clones to adulthood.
The Jotoki were also experts at trade. Their
interstellar trade empire was quite developed for its time, but after
Kzinti were used as mercenaries for many years, the Kzinti revolted and conquered the Jotoki. The Jotoki became the slaves and food-animals of the ferocious Kzinti.
