Are frogs invertebrates or vertebrates

Frogs belong to the group of vertebrates.

Amphibians, amphibians of the order Cerdridae and frogs, adults without tails, eggs are laid in water, fertilized in vitro, hatched into tadpoles, respiration with gills, after mutation, adults mainly use lung respiration, and also use ** respiration. The upper jaw has teeth, usually vomer teeth. shoulder girdle fixed thoracic type, vertebral body uneven type, recommended vertebral transverse process columnar; There is no intermediated cartilage between the two bone nodes at the end of the toes.

Eardrum. Visibly hidden under the skin,** smooth or with wart grains. The tongue is generally oblong, and the posterior end is mostly notched.

Frog is a vertebrate, is an amphibian animal, is the animal kingdom chordate phylum, frogs in the juvenile period will lay eggs in the water, and then after hatching into small tadpoles, small tadpoles can not live on land, need to grow in water all the time, at this time it is to use the gills to breathe. After slowly growing into a frog form, it breathes with its lungs, and even some species can breathe with **, and frogs at this time can live on land. However, frogs are generally slender, and are better at swimming in water, frogs have more developed limbs, and there are more frog species in the world now, and frogs are basically pests as the main food.

Frogs are vertebrates, and simply put, invertebrates are animals that do not have a vertebral column.

Frogs have vertebrates, so they must be vertebrates.

The frog has a backbone, it belongs to the group of amphibians, so it has a backbone. Its body is usually divided into three parts, including the head, torso and limbs, and it usually inhabits ponds, rice fields, rivers, etc., and at night it will be active, mainly eating insects, and will also eat some small fish and shrimp in the water, as well as snails and snails, because it is also known as a type of beneficial insects.

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. The frog's ** can also help it breathe, and its air sac is only found in male frogs, and frogs use their tongues to hunt and have mucus on their tongues.

Frogs are masters of camouflage :

In spring, frogs lay eggs on aquatic plants, and the eggs slowly turn into tadpoles. Tadpoles are black, round with a round body and a long tail, the tadpole grows day by day, first growing hind legs, then front legs, the tail gradually shortens and degenerates, and finally becomes a frog.

The frog is an expert at catching pests, the frog catches pests all by his long and wide tongue, the root of the tongue grows in front of the mouth, the tip of the tongue is backward, and it is also forked, there is a lot of mucus on it, as long as the small flying insects fly by, they jump up suddenly, open their big mouths, quickly stretch out their long tongues, and eat the pests at once. The eyes of a frog are dull to see things that are still and sharp to things that are moving.

Frogs belong to the group of vertebrates.

The frog is an amphibian that belongs to the phylum Vertebrates, Amphibians, Tailless, and Frogidae. Vertebrates are a class of animals with vertebral vertebrae, which are connected by a series of bones that form the backbone and support structure of the animal. The spine of a frog is made up of multiple vertebrae, and in addition to that, they have typical vertebrate characteristics like bones, muscles, nervous system, circulatory system, etc.

It is important to note that although frogs are vertebrates, their bones are different from those of other vertebrates. For example, frogs have softer bones that are not as stiff as mammals and birds, which is one of the main reasons why they are able to jump and hunt as skillful as a predator. In addition, the heart of a frog has three atria and two wide ventricles, which is also one of the things that distinguishes it from other vertebrates.
