Study Notes
Habitat of Grizzly Bears
- Grizzly bears inhabit diverse environments including dense forests, subalpine meadows, open plains, and arctic tundra.
- Found primarily in western Canada, Alaska, Wyoming, Montana, Idaho, and a small population in Washington.
Taxonomy of the Grizzly Bear
- Belongs to the domain Eukarya, characterized by complex cellular structures with DNA housed in a nucleus.
- Under the kingdom Animalia, consisting of multicellular heterotrophic organisms unable to produce their own food.
Scientific Classification
- Scientific name: Ursus arctos horribilis.
Phylum Characteristics
- Classified under the phylum Chordata, which includes organisms with a notochord, nerve cord, pharyngeal slits, and postanal tail.
- Pharyngeal slits functioned initially in filter feeding, retaining food particles for digestion.
Mammalian Features
- The grizzly bear is part of the class Mammalia, defined by four key features:
- Hair for thermoregulation.
- Mammary glands for nurturing offspring.
- Three middle ear bones, unique to mammals for enhanced hearing.
- Endothermic regulation of body temperature, allowing survival in varying environments.
Animal Life Cycle
- Animals, including grizzly bears, have a life cycle primarily as diploid organisms, only exhibiting haploid cells during reproduction (sperm and eggs).
- The zygote is formed when gametes fuse, marking the beginning of the development process.
Movement and Symmetry
- Animals exhibit different modes of movement such as walking, crawling, flying, or swimming and can have bilateral or radial symmetry.
