Do frogs have teeth and what do frogs look like?

Frogs have teeth, mainly in their upper jaws. The teeth of frogs are different from those of many other animals because they belong to the vomer teeth. Moreover, frog teeth work differently than many animals.

While the teeth of other animals play a very important role in chewing when eating, frogs do not chew food, but use their tongues to hunt and swallow their prey. The frog's back is green, smooth, soft, and patterned, and its belly is white. You can hide it in the grass, make it easier to catch pests, and you can also protect yourself.

1. Do frogs have teeth?

Frogs are a type of amphibian, and they are often found near water. The appearance of frogs is more prominent, their heads are very flat, the shape is triangular, the snout is relatively pointed, the eyes are very large, and they appear very prominent on the head, etc. In addition to some of their physical features, they also have some special body structures, such as their teeth.

Frogs have teeth in their upper jaws, but unlike most animals, their teeth are vomerone.

The teeth of frogs are not only different from the teeth of many animals in appearance, but also quite different from other animals in terms of function. The teeth of other animals have the role of predation and feeding, and the teeth play a chewing role when eating. Frogs, on the other hand, use their tongues to hunt and swallow their prey without chewing.

Of course, teeth can still play a role when the frog is eating, which can prevent prey from escaping from the frog's mouth.

2. Do frogs have hearts?

In terms of the general category, frogs belong to vertebrates, and they have vertebrates. Specifically, frogs belong to amphibians, and one of the basic characteristics of amphibians is that they have hearts, and their hearts have two atria and one ventricle. The same goes for frogs, they also have hearts and are divided into atria and ventricles, with two in the atria and one in the ventricles.

In addition to the white belly, the frog has a yellow-green head and back with some black-brown markings. Some have three white marks on their backs. The reason for the frog's green color is a good camouflage, it is almost the same color as the grass in the grass and can protect itself from being detected by enemies.

The frog has two round and prominent eyes on its head, a wide and large mouth, and a long tongue. The back of the body is green with dark stripes, and the belly is white. There are four legs underneath the body, short in front and long in hind with webbing between the toes.

Frogs are amphibians that can jump on the ground and swim in the water, making a "croaking" sound and a loud male call.

Related Notes:

There are many kinds of pigment cells on frogs**: melanocytes with black or brown pigment granules, yellow pigment granules, red pigment cells with red pigment granules, iridescent pigment cells with many reflective crystal plates, etc.

**It is composed of two layers: epidermis and dermis. Several pigment cells are found in the dermis, while there are only smaller melanocytes in the epidermis, and the color in the dermis can be revealed due to the thinner epidermis.

When the frog arrives in a dark environment, the environmental phenomena perceived by the eyes are transmitted to the middle lobe of the pituitary gland through the nerves, so that it secretes melanin, melanin diffuses, and red pigment and yellow pigment contract, so that the red and yellow will retreat, but the melanin is very eye-catching, the frog is dark, and the change of the frog's body color is mainly the result of the activities of the larger melanocytes in the dermis.
