Question

In frog, teeth occur over
A. Lower jaw
B. Upper jaw
C. Both jaws
D. None of the jaws

Answer 1

Hint: Frogs are carnivorous animals. They belong to the class amphibia under the phylum chordata. The frogs act as terrestrial as well as aquatic animals. They mainly feed upon small insects. This means that they definitely do have teeth that they use for only gripping the prey.

Complete answer:
In a frog, teeth are present only in the upper jaw.
The teeth in the upper jaw are called Maxillary teeth. Frogs also have a few teeth on the roof of their mouth and they are called Vomerine teeth.
A frog’s teeth are very small and conical in shape. They are not used for biting or chewing as they swallow the prey that they catch. The teeth are mainly used for keeping a grip on the prey until the time it is swallowed. The teeth types are based upon the type of food the organism eats.
The two major types of teeth that are present in a frog’s mouth are discussed below :
MAXILLARY TEETH
These teeth are present on the upper jaw and are not visible from the outside of a frog’s mouth. They are similar to one another and they help in keeping the prey under control till the frog is ready to swallow it.
VOMERINE TEETH
These are the teeth that are present on the roof of a frog’s mouth. The vomerine teeth work in association with the tongue to prevent the prey from escaping the frog’s mouth.

Thus, the correct answer is (B) Upper jaw.

Note: An interesting point about frogs is that they have shedding teeth. Like humans, frogs also lose their teeth. Though humans lose their teeth only once in childhood, frogs can lose their teeth and grow new ones multiple times throughout their life. Almost all frogs have teeth only in the upper jaw, Gunther’s marsupial frogs are the only species of frogs that have teeth on their lower jaw as well.
