Study Notes
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.
