Different types of individuals (i.e., castes) show distinctive phenotypes specialized in specific colony tasks. The whole colony is coordinated by interactions among colony members. 2   New unpublished work suggests greater complexity in the termite caste system, greater communications abilities, as well as greater termite intelligence than previously assumed. This new work is summarized below.   Worldwide there are about 3000 species of termites including about 360 species living in Australia. The new subterranean species, not yet named, was found living on a great wood--mud ball suspended on a 100 foot termite built vine anchored to the top of a cave in New South Wales. When initially discovered the ball was swinging along an orbit with a periodic length of about 7 feet.   Building upon the work of bacteriologists 3 , the investigators d
