Like termites, terabytes are organized into castes but are even more specialized than any present-day insects. Like their termite ancestors, Terabytes are vegetarians. While the algae in the mound is growing, they feed on those found on the Garden worms around the pools. Terabytes harvest algae in greenhouses and they get them from garden worms.
|Transporters- which carry other legless castes to a specified area.|
|Gum-spitters-which do nothing else but spit sticky gum for building purposes|
|Rock-borers- which use chemicals to dissolve the hard limestone under the desert to get to the underground pools below (the chemical in question is concentrated hydrochloric acid).|
|Biters- that we never see, bite at the limestone along with rock-borers to get to the pools below. As their names imply, they have strong jaws.|
|Water-carriers - which suck up water to water the algae that the colony grows.|
King -Is chosen by the queen and carries the queen.
|Nurses-nurses the eggs.|
|Builders- Assists Gum-spitters by building the mounds.|
|Warriors- Spit chemicals much like the rock borers, but for defensive purposes.|
|Queen- lays eggs and is the center of the colony.|
The terabytes cultivate gardenworm algae in their mounds, using the water-carriers to water it, and getting it sunlight from transparent panes in the top made of terabyte saliva. Gardenworms are either found vulnerable, lying around near oases, or inaccessibly swimming around in the underground caves. The transporter terabytes carry gum-spitters to the attack point and the gum-spitters freeze the worms in their tracks. Then other transporter terabytes apprehend the worms to grab some algae to take back to their enormous nests. Underneath the nests are a series of caverns that disperse heat from the nests. This is so the terabytes don't get hot in the blistering desert, the largest the Earth has ever seen.
