Key Differences
Beavers are primarily known for their remarkable ability to build dams and lodges using tree branches and mud, which play a critical role in ecosystem engineering by creating wetlands. On the other hand, the platypus is distinctive for its unusual combination of mammalian and reptilian traits, such as laying eggs and having a bill similar to a duck's.
The beaver, found in North America and parts of Eurasia, is a large rodent adapted to a semi-aquatic life, with webbed feet and a flat tail that aids in swimming. In contrast, the platypus is native to eastern Australia, including Tasmania, and is fully adapted to an aquatic lifestyle with webbed feet and a streamlined body.
Beavers are known for their impact on the environment and are considered a keystone species due to their dam-building activities that create new habitats for various species. Whereas, platypuses are bioindicators, their health and population reflecting the condition of their aquatic environment.
The social structure of beavers involves family units where both parents help in the upbringing of the young. Conversely, platypuses are solitary animals, with minimal interaction outside of the breeding season.
Beavers possess a set of powerful front teeth that continuously grow throughout their lives, used for gnawing on wood. Meanwhile, the platypus is equipped with electroreceptors in its bill, allowing it to detect prey underwater by sensing electric fields.

Beaver
Beavers are large, semiaquatic rodents in the genus Castor native to the temperate Northern Hemisphere. There are two extant species: the North American beaver (Castor canadensis) and the Eurasian beaver (C. fiber).
Platypus
The platypus (Ornithorhynchus anatinus), sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species appear in the fossil record.
Beaver
