速记技巧：该词中的“edent”是由“dent”派生出来的词，意为“牙齿”，而“ate”则是动词后缀，表示“吃”的动作。因此，可以将该词拆解为“没有牙齿的”，从而快速记住其含义。

Edentate animals are fascinating creatures that lack teeth and jaws, making their lives very difficult. However, this unique group of organisms has evolved over time and has adapted to survive in various environments.
