    Classification Difficulties in Animals

    • Classification challenges arise in several animals, including armadillos, bats, whales, duck-billed platypuses, and pangolins.

    Armadillos

    • Armadillos possess an outer shell composed of scales from epithelial tissue, typically found in reptiles; however, they are categorized as mammals.

    Bats

    • Bats exhibit characteristics commonly associated with birds (aves) yet are classified within mammals, complicating their classification.

    Whales

    • Whales are warm-blooded and possess a four-chambered heart, which distinguishes them from fish, contributing to classification difficulties.

    Duck-Billed Platypus

    • The duck-billed platypus has traits typical of the aves class, such as webbed feet and the ability to lay eggs, despite being a mammal.

    Pangolins

    • Pangolins are mammals that exhibit similarities to both aves and reptilia classes, characterized by keratin scales and an internal grinding mechanism for food similar to a gizzard.
