Study Notes
Dentition
- Dentition refers to the arrangement and types of teeth in an organism's mouth.
- Dental formulas are used to represent the number and types of teeth a species has.
- Analyzing the teeth an organism has can provide insight into its diet and adaptation.
Dental Formula Comparisons
- Canine teeth are absent in some species, such as the zebra, elephant, and hedgehog, indicating their primary function is not for tearing meat.
- Canine teeth are primarily used for tearing meat.
- Molars are present in all species, suggesting their essential role in grinding food, regardless of diet.
- Plant material is difficult to digest because it contains cellulose, which is harder to break down.
Additional Information
- Hedgehog's Dental Formula: 3 - 1 - 3 - 1
- Herbivores (plant-eaters) often have flat molars and wide premolars for grinding.
- Carnivores (meat-eaters) usually have pointed canine teeth for tearing.
- Omnivores (both plants and meat) typically have a combination of sharp and flat teeth for both tearing and grinding.
