What are the basic differences between the reptilian and fish scale?
Fish scales are smooth to help them glide through the water, and some reflect light to help camouflage them underwater. Unlike reptiles, the scales of bony fish are made of enamel and dentine (like teeth) and they can be detached individually from the skin.
What is the difference between reptile and animal?
Mammals are warm-blooded animals whereas reptiles are cold-blooded animals. Mammals have hair or fur surrounding the body while reptiles have scales. The main difference between mammals and reptiles is that mammals have mammary glands to feed their babies with milk whereas reptiles do not have mammary glands.
What are the common characteristics between fish and reptiles?
Although separated by millions of years of evolutionary history, most fish and reptiles are vertebrates who share a number of similar traits, including the presence of a vertebral columns and scales, as well as ectothermic metabolisms.
Is a fish a mammal or a reptile?
Fish are not mammals because most of them are not warmblooded, though some sharks and species of tuna are exceptions. They do not have limbs, fingers, toes, fur, or hair, and most of them can’t breathe air, though the lungfish and the snakehead are also exceptions.
Is a crab a reptile?

Is a fish a reptile?

Are fish considered reptiles?

Is a fish a reptile or amphibian?
Fish are neither amphibians nor reptiles. They are fish. Amphibians are a derived clade of lobed-fin fish. Reptiles are a derived clade of amphibians, which makes them an even more derived clade of fish.
What are the similarities between amphibians and reptiles?
Similarities Between Amphibians and Reptiles Both amphibians and reptiles belong to the phylum chordate under the kingdom Animalia . Both amphibians and reptiles are ectothermic (cold-blooded) animals. Some amphibians and reptiles have four limbs. Both amphibians and reptiles have a heart with three chambers.
Are fish mammals reptiles or amphibians?
Thus fish are neither mammals or amphibians. Fish breathe through gills instead of lungs, breathe water instead of air, lay eggs, live in water their entire lives, have fins instead of limbs.
Therefore, fish are not reptiles since reptiles evolved from fish-like creatures which existed more than 370 million years ago. Reptiles and fish are both ectothermic (cold-blooded) animals whose internal sources of heat are insignificant and cannot regulate their body temperature.
