Are fish similar to 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. However, as both groups are very speciose, numerous exceptions exist.
Why are fish not reptiles?
All fish have scales, except for those that fall in the cartilaginous category. Fish have fins that help them swim, while reptiles have tiny legs as limbs for mobility, and in the case of snakes, it is scales. Some examples of reptiles are crocodiles, alligators, and snakes – they can be found in both land and water.
What are the three classifications of fish?
Fishes are typically divided into three groups: superclass Agnatha (jawless fishes), class Chondrichthyes (cartilaginous fishes), and superclass Osteichthyes (bony fishes).
Is a shark a fish or a mammal?
Sharks are fish. They live in water, and use their gills to filter oxygen from the water. Sharks are a special type of fish known because their body is made out of cartilage instead of bones like other fish.
Do fish lay eggs?
Fish reproduce by bearing live young or by laying eggs. Livebearers give birth to fully formed and functional young called fry. The eggs are fertilized and hatch within the female.
Is a turtle a reptile?

Did reptiles evolve fish?
Amphibians, reptiles, mammals, and birds evolved after fish. The first amphibians evolved from a lobe-finned fish ancestor about 365 million years ago.
How are reptiles different from fish?
The main difference between Fish and Reptiles is that fishes breathe through gills while reptiles do not have gills. They respire through the lungs itself. Their ribs can expand and contract which allows their lungs to have greater capacity than amphibians. Fish belongs are the largest existing vertebrates species.
Can fishes feel pain?
Neurobiologists have long recognized that fish have nervous systems that comprehend and respond to pain. Fish, like “higher vertebrates,” have neurotransmitters such as endorphins that relieve suffering—the only reason for their nervous systems to produce these painkillers is to alleviate pain.
