The term 'Six-Legged Animal' can be solved by the word 'INSECT'. Insects are a type of arthropod and the most diverse group of animals on the planet, with over a million described species and representing more than half of all known living organisms. They have six legs and three body parts: head, thorax, and abdomen. Insects play an important role in the environment, providing food for other animals, pollinating plants, and helping to break down organic matter.
