What is the common name for Testudinidae?

Characteristics of the Testudinidae

Tortoises, or members of the Testudinidae family, share several distinct characteristics:

  • Shell: One of the most recognizable features of tortoises is their hard, protective shell. The shell is composed of two parts, the carapace (the upper part) and the plastron (the lower part), which are fused together. The shell provides excellent protection against predators.
  • Land-dwelling: Unlike turtles, which are adapted for aquatic life, tortoises are primarily terrestrial. They have sturdy legs and feet that are adapted for walking on land.
  • Herbivorous diet: Tortoises are herbivores, feeding on various plant materials such as grasses, leaves, fruits, and flowers. Their beak-like mouthparts are specialized for grazing on vegetation.
  • Long lifespan: Tortoises are known for their longevity. Some species can live for several decades, with a few individuals reaching over a hundred years old.
  • Slow metabolism: Tortoises have a slow metabolic rate, which contributes to their long lifespan. They are also able to withstand periods of drought and scarcity of food by slowing down their metabolic processes.
