Some examples of reptiles are turtles, snakes, lizards, alligators, and crocodiles. Metamorphosing from a larval stage to the adult stage is what the Amphibian is known for. Reptiles, amphibians, fish, birds, mammals, etc. Frogs are the most common amphibian in the United States. Most frogs live in tropical and subtropical regions of the world, including the tropics of South America, Africa, Asia, Australia, New Zealand, Europe, the Middle East and North America.
Some of these species are endangered, while others are threatened with extinction due to habitat loss, over-exploitation, pollution, disease, or other factors. U.S., the largest frog species is the American alligator frog (Alligator mississippiensis), which can grow up to 6 feet (1.2 m) in length.

Are crocodiles considered mammals?
For a long time, crocodiles have been separated from the rest of the animal kingdom, just like birds and mammals. In fact, the word “crocodile” is derived from a Greek word meaning “sea serpent” or “serpent”. The word crocodile is also used to refer to a type of fish that lives in the deep sea.
It is not a reptile or amphibian, but rather a fish-like creature that can grow up to 10 feet in length and weigh as much as 100 pounds. They are found throughout the world, including the United States, Canada, Australia, New Zealand, South Africa, and parts of Europe and Asia.
Why is crocodile not a mammal?
Amphibians are born in water while crocodiles and mammals are born on land. Amphibians and mammals lay eggs in the water while crocodiles lay their eggs on land. Reptiles, like snakes, are members of the reptile family. Snakes, on the other hand, belong to the snake family, which also includes lizards, turtles and tortoises. The difference between reptiles and snakes is that snakes are carnivores, while reptiles are herbivores.
Why crocodiles are not reptiles?
Lizards do not possess gizzards, while the only reptiles that have gizzards are crocodilians. Crocodilians have a four-chambered heart. The reptile’s heart has a three-chambered one. The thecodontine heart is located in the middle of the chest in crocodiles. The gizzard is the largest part of a crocodile’s body. It is about the size of an adult human’s hand and is made of cartilage, bone, muscle, and fat.
Gizzard size is determined by the amount of food that the animal can consume in a day. The largest crocodiles can eat up to 1,000 pounds (454 kilograms) of prey in one sitting. This is more than twice as much as any other reptile, including the giant pythons and alligators.
Are mammals technically reptiles?
The reptiles are paraphyletic since they exclude both birds and mammals. These evolved from dinosaurs and from early therapsids, which were thought to be the ancestors of modern birds.
The new study, published in the Journal of Vertebrate Paleontology, is the first to show that theropods, the group of dinosaurs that includes birds, were not the only group to evolve into reptiles.
It also shows that some of the earliest reptiles, such as the sauropodomorphs and the ornithischians, may have been closely related to dinosaurs.
Is a dolphin a mammal?
Dolphins are mammals, not fish, and they are different than dolphin, which is also known as mahi-mahi. Like every mammal, dolphins are warm blooded. Unlike fish, dolphins breathe air through their lungs, which are located in the middle of their chest. Dolphins also have a heart that pumps blood to the rest of the body, unlike fish which have no heart at all.
The heart of a dolphin is about the same size as a human heart, but it is not as powerful. A dolphin’s heart beats at a rate of about 20 beats per minute, compared to a fish heart which can beat at more than 100 bpm. This means that dolphins have the ability to pump blood for longer periods of time than fish.
Dolphin’s lungs are very similar to those of humans, except that they are much larger. They are made up of two chambers, called the trachea and the bronchi, and each chamber has its own airways. These chambers are connected to each other by a series of air sacs called bronchioles. In addition to breathing air, the lungs of dolphins also contain a small amount of bile.
Is a alligator a mammal yes or no?
An alligator is not a mammal or an amphibian. Eggs on the bottom of the ocean hatch into a reptile that grows up to be an adult. Alligators are born in the water, but they do not live in it.
They are the largest of alligators and can reach a height of over 30 feet. Their skin is covered with scales, making them look like a cross between a crocodile and an iguana. The scales are made of keratin, the same material that makes up fingernails and toenails.
Is a shark a mammal?
Sharks are fish, even though some people believe they are mammals due to how big some of them can get and because some give birth to live young. Fish were among the first animals to evolve into land animals. The word “fish” is derived from the Greek word for “water” and “fishes” means “sea creatures” in Greek. Greek mythology, the sea god Poseidon was said to be the father of all fish.
Is snake a mammal or reptile?
Reptiles are turtles, snakes, lizards, alligators and crocodiles. Unlike salamanders, reptiles have dry skin that prevents them from drying out and can live hundreds of years. Their venom is powerful enough to kill an adult human in a matter of minutes. The venom can also cause paralysis and death if it is injected into the bloodstream.
