What characteristics do fish and amphibians have?

Both groups have gills and fins for at least part of their lives, though most amphibians lose their aquatic traits as adults. They both also have skin and eggs that need to remain moist, and rely on water for reproduction.

How are amphibians and fish the same?

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.

Which characteristic do amphibians and reptiles have in common?

They definitely have traits they share. For example, they are both ectothermic, or cold-blooded animals, meaning their body temperature relies on the temperature of their habitat. Reptiles and amphibians also are both vertebrate animals, meaning they have backbones.

What are the similarities between mammals and amphibians?

Similarities Between Mammals and Amphibians

  • Mammals and amphibians represent two classes of the phylum Chordata.
  • Both mammals and amphibians consist of a notochord, dorsal central nervous system, pharyngeal gill slits, and a post-anal tail.
  • Both mammals and amphibians are deuterostomes with bilateral symmetry.

What is the characteristics of amphibians?


  • Amphibians are vertebrates.
  • Their skin is smooth and slimy.
  • Amphibians breath through their skin, as well as their lungs in some cases.
  • Amphibians are cold-blooded.
  • They have a complex life cycle (larval and adult stages).
  • Many species of amphibians vocalize.

How are frogs and fish similar?

How are fish and frogs similar? Both frogs and fish belong to the phylum Chordata and the subphylum Vertebrata. This means that both frogs and fish have a spinal cord and backbone. Frogs and fish share these traits with other vertebrates, like mammals and reptiles.

What are the characteristics of a fish?

5 Characteristics That All Fish Have in Common

  • Gills to Breathe.
  • Swim Bladders.
  • Fins for Movement.

Is a fish an amphibian?

Fish and amphibians are two distinct groups of vertebrates in general. However, their living environments are sometimes similar, but amphibians could inhabit both aquatic and terrestrial environments. Apart from that, important biological features of fish and amphibians are distinctive.

What is the evolution of amphibians?

Amphibians are a class of animal that includes modern-day frogs, toads, salamanders, newts, and caecilians . They first evolved from lobe-finned fish and primitive tetrapods about 340 million years ago. Sometimes this date is incorrectly given as 400 or 380 million years ago, but fossils have not been unearthed from these periods.

How did amphibians evolve?

As they evolved from lunged fish, amphibians had to make certain adaptations for living on land, including the need to develop new means of locomotion. In the water, the sideways thrusts of their tails had propelled them forward, but on land, quite different mechanisms were required.
