Snakes are included in the class reptilia. Vertebrata has class reptilia in it. The embryo’s notochord is the source of the vertebral column. The snake is a member of the order cephalopoda because it has the vertebral column. Mammalia includes mammals, birds, reptiles, amphibians, and fish. Mammals are divided into two groups: mammals and non-mammals. Marsupial mammals are mammals that are related to reptiles and birds.
For example, the platypus is an example of a mammal that belongs to this group. Placental mammal is the term used to refer to mammals belonging to a group that does not belong to the other two major groups.

Are snakes reptiles or invertebrates?
Snakes, lizards, turtles, crocodilians, and birds are reptiles. Like all animals, reptiles have skeletons. Scales help protect reptiles from losing water. Rabbits and other small mammals are mammals. Mammals are the largest group of animals in the animal kingdom. They are divided into four major groups: mammals, birds, fish and amphibians.
Are snakes non vertebrae?
Though very flexible, snakes have many vertebrae (small bones that form the backbone of the body) that are arranged in a variety of ways. Some snakes, such as rattlesnakes and cobras, have only one spine, while others have two or more. Snakes also have a number of muscles that help them move their bodies.
These muscles are called musculature, and they are divided into two main groups: flexor and extensor muscles. For example, a snake’s tail can be flexed forward or backward, depending on the direction the tail is facing. A snake can also use its tail as a spring to propel itself forward and backward.
Are snakes reptiles yes or no?
Reptiles are turtles, snakes, lizards, alligators and crocodiles. Unlike salamanders, reptiles only breathe through their lungs and have dry skin that prevents their skin from drying out. Reptiles can live for hundreds of years. Their skin is thick and tough, making them difficult to kill with a knife or other sharp object.
A rattler’s venom can kill an adult human in a matter of minutes.
Does a snake have bones?
The unique bone structure of their jaws allows them to swallow many times their own body weight. A snake’s jaw is made up of two parts: the upper jaw and the lower jaw. These parts are connected by a series of bones called the maxillae (pronounced muh-LEE-luhs).
The upper and lower jaws of a snake are attached to each other by ligaments, which are made of cartilage and connect the jaw bones to the rest of the body. When the jaws are closed, the muscles that control the opening and closing are located in the neck and jaw muscles.
A snake can open and close its jaws in a variety of ways, depending on the type of prey it is eating. For example, some snakes will open their mouths wide, while others will close them tightly. Some snakes, such as rattlesnakes, will bite their prey with their fangs. Others, like boas and boa constrictors, use their mouth parts to crush the prey.
Is fish a vertebrate?
Fish are aquatic vertebrate animals that have gills but lack limbs with digits, like fingers or toes. Vesicals are animals with internal backbones. The general shape of most fish is streamlined, but some are more streamlined than others. Some fish have fins, while others have no fins at all. The fins of some fish, such as the bluefin tuna, are so long that they can be used as a means of propulsion.
Fishes are generally found in the ocean, although some species are found on land as well. Predatory fish include sharks, rays, and raysharks. They are also known as bottom-dwellers, because they live on the bottom of the sea. Herbivores include fish that feed on plants, algae, crustaceans, mollusks and other invertebrates. Many of these fish live in groups called clades. Clades are groups of related species that share a common ancestor.
