Reptiles are turtles, snakes, lizards, alligators and crocodiles. Unlike salamanders, reptiles have dry, flaky skin that prevents them from drying out. Amphibians and reptiles are called herpetofauna. “Herps are the most diverse group of animals in the world.
Herps range in size from a few millimetres to several metres in length, and they have a wide range of colours, shapes and patterns. Some herps, such as the giant pufferfish, are so large that they cannot be seen with the naked eye, but they can be identified by their distinctive colour patterns and the way they move.

Is a turtle a fish or a mammal?
A turtle is classified as a reptile rather than a mammal. This classification is based on how turtles begin their lives. Turtles begin life as hatchlings in the wild. They are born with a shell, which is made of keratin, the same substance that makes up our fingernails and hair.
The shell protects the turtle from the elements and protects it from predators. As the hatchling grows, it sheds its shell and grows into its adult form. Turtles can live for up to 20 years, but most live only a few months.
Are all turtles amphibious?
Amphibians are adapted to live in both water and land. A reptile is covered by its body. Amphibian is an umbrella term that covers a wide range of animals, including reptiles, fish, birds, and mammals.
Why tortoise is not an amphibian?
A tortoise is not a true amphibian animal; it is a reptile. A tortoise can live on land as well as in water, but its body is covered by a shell. The presence of protective shells is not a characteristic feature of all tortoises. Turtles and iguanas are members of the same family of reptiles. They share a common ancestor that lived in the Cretaceous period (about 145 million years ago).
The two species are not closely related, but they are related to each other in other ways. For example, both turtles are herbivores, and both are carnivores. However, turtles have a much larger mouth than iguans, which allows them to swallow larger prey, such as fish and small mammals. Turtles also have much longer legs and a longer tail, making them more agile and able to run faster than their smaller cousins.
What type of mammal is a turtle?
Animals with fur or hair on their bodies are called mammals. Turtles have no fur or hair, but they do have scales. The scales are made of keratin, the same substance that makes up our fingernails and toenails. Keratin is a protein that is found in the skin of many animals, including humans. The scales on a turtle’s back are called carapace.
They are covered with scales called scutes. Scutes are also found on the backs of other reptiles, such as snakes, lizards, crocodiles, turtles, and tortoises. When a reptile is attacked by a predator, it has to shed its skin in order to protect itself from the attack. This process is called exoskeletons.
It is made up of two layers: the epidermis (the outermost layer) and the dermis, or the second layer, which contains the blood vessels, nerves, muscles, tendons, ligaments, cartilage, skin, hair follicles, etc. These layers are separated by an outer sheath called the stratum corneum (SC).
Is 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. In Greek mythology, the sea god Poseidon was said to be the father of all fish.
How old are turtles as a species?
Turtles are thought to have originated around 230 million years ago during the triassic period, but what they evolved from remains a mystery. A new study, published in the journal Nature Communications, suggests that the turtles may have evolved into a new group of reptiles called the Cretaceous-Paleogene (K-Pg) turtles, which are thought to be the ancestors of all modern turtles today.
The study was led by a team of researchers from the University of California, Santa Cruz, and the National Museum of Natural History in Washington, D.C., and was funded by the U.S. National Science Foundation, the Natural Sciences and Engineering Research Council of Canada (NSERC), the Canadian Institutes of Health Research (CIHR), and National Geographic Society.
