The last caste is the soldier caste, which consists of blind and wingless termites that are bigger than the workers. Their heads are extremely hard, and they have powerful jaws and legs, but the rest of their body is soft and weak. The soldiers main duty is to protect the colony against attack, mostly done by ants. The funny thing about soldier termites though, are that they can protect and care for the colony, but they can't take care of themselves. Soldier termites must be fed and groomed by workers all the time.
All termite castes consist of both sexes, and unlike ants, the kings can live as long as the queens.
Termites live most abundantly in warm regions, like Africa, Australia, and in the Amazon regions. Some termites build huge mounds that are made of soil mixed with saliva, and can be high as twenty feet. Inside of the mounds, are numerous chambers and galleries. In the center of the mound, there is a closed cell where the king and queen are kept. Inside the cell, the queen's body swells until it is large enough to hold many thousands of eggs.
