In general, amphibians like frogs live on both land and water, and fish live in water. However, some fish can live on land, and some frogs can only live in water. The climbing perch (Anabas testudineus) is a fish that can breath air and crawl along land for short distances.
A fish is an animal that lives only in the water, whereas a reptile lives in both land and water. A fish is an aquatic vertebrate that is cold blooded or ectothermic. Some examples of fish are lamprey, sharks, ray fish etc, while lizards, crocodiles, snakes, turtles etc are reptiles.
The word amphibians means two lives. Amphibians spend their lives in water and on land. There are more than 4,000 different kinds of amphibians. Members of this animal class are frogs, toads, salamanders, newts, and caecilians or blindworms.
Birds are warm-blooded animals that lay eggs, they have feathers, a beak, wings and have the ability to fly with some exception (flightless birds). Fishes are aquatic animals having scales and are cold-blooded, they receive oxygen from water and they have gills instead of lungs.
Shark. Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays.
Fish have scales that arise from dermal -- bony -- tissue and have a somewhat similar composition to bone. Turtles and crocodilians also possess dermal scales, but they arise via a different process. These scales form from the epidermis, somewhat like those of snakes and lizards do.
Vertebrates are animals that have a backbone or spinal column, also called vertebrae. These animals include fish, birds, mammals, amphibians, and reptiles. How are they classified? Vertebrates are classified by the chordate subphylum vertebrata.
Most amphibians breathe through lungs and their skin. Tadpoles and some aquatic amphibians have gills like fish that they use to breathe. There are a few amphibians that do not have lungs and only breathe through their skin.
Five Characteristics of Amphibians
- Unshelled Eggs. Living amphibians produce much different eggs than strictly terrestrial organisms like reptiles do.
- Permeable Skin. While caecilians have scales similar to fish, most other amphibians have moist, permeable skin.
- Carnivorous Adults.
- Distribution.
- Courtship Rituals.
Unlike mammals, fish are cold-blooded (ectothermic). This means that they do not maintain a constant internal body temperature; instead, their temperature is greatly influenced by their environment. True fish have a backbone and fins. Most also breathe with gills and have scales that cover their bodies.
Fish and snakes are both in the phylum of chordates. One could consider all chordates very different cousins. However, fish and snakes are in different classes of chordates. So they are rather distant cousins.
Fish are gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups.

Sharks are neither amphibians nor reptiles; they are fish.
Crabs are not amphibians or reptiles; they are crustaceans. Crustaceans are semi-aquatic creatures that have exoskeletons. This group includes crabs, lobsters, shrimp, and crawfish.
As far as I know, all fish do have gills. However, not all fish can breathe through their gills. Lungfish for example live in freshwater habitats and have evolved lungs which they use to breathe air.
Frog legs are rich in protein, omega-3 fatty acids, vitamin A, and potassium. They are often said to taste like chicken because of their mild flavor, with a texture most similar to chicken wings. The taste and texture of frog meat is approximately between chicken and fish.
The big difference is that frogs are amphibians and breathe air. Some frogs bypass this larval stage. Fish live in water, and have gills to extract oxygen from the water. There are a few fish, such as the walking catfish and the betta splendens that breathe air, but very few air breathing fish exist.
The main difference between Fish and Tadpole is that the Fish is a vertebrate animal that lives in water and (typically) has gills and Tadpole is a larva of amphibians.
Frogs are not seafood. They breathe air.
What are four characteristics shared by most fishes? live in water, strong body and brain, have fins, and have scales.
Any group of fish that stays together for social reasons is said to be shoaling, and if the shoal is swimming in the same direction together, it is schooling. p365. About one quarter of fish shoal all their lives, and about one half of fish shoal for part of their lives.
Classification of Fish: Fish, the member of the Animalia Kingdom is classified into Phylum Chordata and Vertebrata Subphylum. Fishes poses notochord, tubular nerve chord, paired gills, segmentation of the body parts, post anal tail, ventral heart, and an endoskeleton to be the member of the Chordata.
Fish do not have lungs. In order to be classified as a fish, the animal in question must use gills instead of lungs. Water flows over the gills and
Fish are a class of aquatic vertebrates. The combination of gills, fins and the fact that they live only in the water make fish different from all other animals. And somenot so much. Most fish have a skeleton made of bone but some, like sharks, have a skeleton made of cartilage.
Frogs belong to a group of animals called amphibians. Frogs are cold-blooded which means that their bodies are the same temperature as the air or water around them. When they are cold they will lay in the sun to warm up and when they get too warm they will go into the water to cool their bodies off.
Amniotes include synapsids (mammals along with their extinct kin) and sauropsids (reptiles and birds), as well as their ancestors, back to amphibians. Amniote embryos, whether laid as eggs or carried by the female, are protected and aided by several extensive membranes.
Most amphibians live part of their lives underwater and part on land. Amphibians reproduce by laying eggs that do not have a soft skin, not a hard shell. Most females lay eggs in the water and the babies, called larvae or tadpoles, live in the water, using gills to breathe and finding food as fish do.
Most amphibians breathe through lungs and their skin. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (If they get too dry, they cannot breathe and will die). Tadpoles and some aquatic amphibians have gills like fish that they use to breathe.
Yes. Amphibians are cold blooded and depend upon their surroundings to regulate their internal temperature. The only warm blooded animals currently on the planet are mammals and birds. All amphibians are cold blooded, however they inhabit different climates.
There are no true marine amphibians because amphibians must live in fresh water, and their body composition makes them unable to tolerate pure salt
Yes, Amphibians are cold-blooded. The difference between cold-blooded and warm-blooded animals lies in how species control their core body temperature. Cold-blooded animals (known as ectotherms) are at the mercy of their environment.
