    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.
