Animal Teeth Arrangement

​Objective: I will learn how animal teeth are structured to help them survive in their environments.

​

DOL: Given 5 questions, I will compare teeth of various animal species into herbivores, omnivores and carnivores by classifying them into what nutritional diets they obtain their energy from. Answering with 100% accuracy.

How does the alignment of your teeth affect the way you bite and chew your food?

Sharks have multiple rows of sharp, serrated teeth, and these teeth are arranged in a way that helps them catch and consume prey efficiently. When a shark loses a tooth, a new one from the row behind it moves forward to replace it. This constant replenishment ensures that sharks always have sharp teeth ready for hunting. The arrangement of teeth varies depending on the type of shark and its diet. For example, sharks that primarily eat fish have pointed, needle-like teeth that are perfect for gripping slippery prey, while sharks that eat larger animals, like seals, have broader, triangular teeth that are better suited for cutting and tearing flesh. The unique arrangement and structure of a shark’s teeth allow them to maximize their efficiency as predators in different environments. Why do you think different species of sharks have evolved to have different types of teeth, and which arrangement do you think is most effective for catching prey?

Response Card-
Sharks have multiple rows of sharp, replaceable teeth, reflecting their carnivorous diet and the need for efficient predation. The continuous replacement ensures they always have functional teeth. In contrast, elephants have large, ridged molars adapted for grinding tough plant material. Their tusks, which are modified incisors, serve various functions, including digging for water and defense.

​During episodes of intense ivory poaching, those big incisors become a liability.

Now researchers have pinpointed how years of civil war and poaching in Mozambique have led to a greater proportion of elephants that will never develop tusks.

During the conflict from 1977 to 1992, fighters on both sides slaughtered elephants for ivory to finance war efforts. In the region that's now Gorongosa National Park, around 90% of the elephants were killed.

The survivors were likely to share a key characteristic: half the females were naturally tuskless — they simply never developed tusks — while before the war, less than a fifth lacked tusks.
