Fish vs. Reptile: Know the Difference
By Shumaila Saeed || Published on February 1, 2024
Fish are aquatic, gill-breathing vertebrates with fins, mostly covered in scales, while reptiles are primarily land-dwelling, lung-breathing vertebrates with scaly skin.
Key Differences
Fish are aquatic creatures that live exclusively in water and use gills to extract oxygen from water. Reptiles, on the other hand, are primarily land-dwelling animals that breathe air through lungs and can live in a variety of terrestrial habitats.

The body temperature regulation differs significantly; fish are cold-blooded and cannot regulate their body temperature internally, unlike reptiles which are ectothermic but can regulate their temperature through behavioral means.

Fish are covered in scales, which are often smooth and overlap each other. Reptiles also have scales, but these are thicker, more protective, and do not overlap in the same way as fish scales.

Reproduction in fish varies widely, with most species laying eggs (oviparous), but some are live-bearing (viviparous). Reptiles predominantly lay shelled eggs on land, but some species are also capable of live birth.

Fish swim using their fins and have bodies shaped to move efficiently in water. Reptiles, however, have limbs (if present) adapted for moving on land, and their locomotion varies greatly from swimming to crawling and climbing.
