No - but there are certain similarities between the two, because fish are the common ancestors of amphibians, reptiles and mammals. ... So no, fish are not reptiles, but reptiles are - in a very long and roundabout way - partly fish.

Actually, birds and mammals are technically reptiles, as they descended from the very first reptile. However, when we calibrate our microscope appropriately, we find that birds are more intimately related to dinosaurs, as they branched off from a dinosaur.

1. Mammal or fish? Many mistakenly consider mantas to be mammals. In reality, they are fish, belonging to the same class (Elasmobranchii) as sharks, and other species of ray.

Most reptiles today are cold-blooded, meaning their body temperature is determined by how warm or cold their surroundings are. ... So, when they found reptile teeth with different oxygen signatures, it probably meant that those reptiles had warmer body temperatures than the fish did.

Often confused for a snake, the slow worm is in fact a legless lizard. Snakes and lizards are both reptiles, but there are a number of differences between them; the biggest give away is that slow worms have eyelids. They have a short, partially forked tongue which, unlike snakes, they can't stick out of a closed mouth.

Fish, mammals, amphibians, reptiles, and birds are separate categories of vertebrate animals (animals that possess a spine). Each category has different characteristics from the other. Thus fish are neither mammals or amphibians.

Alligators are large reptiles, members of the order Crocodylia. Alligators and crocodiles are, therefore, closely related, and people often confuse one with the other; however, these two reptiles are very different. An alligator is distinguished by its wide, rounded snout and black color.

Vertebrates can be subdivided into five major groups: fishes, amphibians, reptiles, birds, and mammals. Amphibians, reptiles, birds, and mammals are ranked as classes. The fishes includes five different classes: Myxini, Hyperoartia, Chondrichthyes, Actinopterygii, and Sarcopterygii.

Mosasaurus once ruled the Cretaceous seas. An immense seagoing lizard—and not an actual dinosaur—Mosasaurus can use its fearsome array of teeth to catch fish, birds, and other marine reptiles—even great white sharks.

We'll start with the "reptilian" similarities of birds. Like all other reptiles, birds have scales (feathers are produced by tissues similar to those that produce scales, and birds have scales on their feet). Also, birds lay eggs like other reptiles.

Technically, birds are indeed reptiles. Birds descended from the very first reptile. Birds are also dinosaurs because they descended from a dinosaur.

Almost all reptiles, amphibians, and fish come from eggs. But, while most mammals have a live birth, there are two mammals that do lay eggs instead. Animals and their eggs are incredibly diverse.

Fish, amphibians and reptiles belong to a group called ectotherms meaning that these animals do not produce heat to maintaining a constant and normally high body temperature (as is the case for birds and mammals). Instead they rely on the environment and their own behaviour to control their temperature.

An eel is a fish. A fish is an animal that is a vertibrate (has a backbone, unlike insects, crabs.. But like mammals, birds and reptiles) and has gills (some have lungs as well, but also will have gills), and does not have arms or fingers. ... Such animals are called amphibians.

No, most fish are neither mammals nor amphibians, because most fish cannot breath air. The few types of fish that can breath air are amphibious, because they also breath water. Neither. The amphibians, reptiles, birds, and mammals evolved from fish, so they could all be considered fish.
