write classification of fish and classification of lizard
Answers
Explanation:
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. The reptile is also a cold blooded animal that is covered by scutes or scales. Fish also have scales, although they are absent in cartilaginous fish. They have paired or unpaired fins, while reptiles have small legs for limbs. Fish are found abundantly in the sea or in freshwater. You may see reptiles in water or on land like crocodiles and alligators in the rivers and lizards and chameleons in your house or garden. Some examples of fish are lamprey, sharks, ray fish etc, while lizards, crocodiles, snakes, turtles etc are reptiles.

This is not the case with fish that develop eggs outside their body with external fertilization taking place. The fins of fish are actually modified limbs that have been adjusted for swimming. Reptiles have claws on their feet (except for the legless lizards). Their eggs are amniotic, which makes them suitable for laying eggs on land. Fish breathe through gills which are made out of thread like structures known as filaments. They gulp in fresh air from the mouth and release it through the gills. Reptiles have a solid skull with nasal openings; they have lungs that are ventilated through axial musculature.

The reptiles generally have a three chambered heart with atria, a partitioned ventricle and two aortas. In contrast to this, the heart of fish is a two chambered organ that allows for circulation of blood through the atrium into the ventricle. The excretory system of reptiles is performed by two kidneys which cannot produce urine. Hence, water absorption in reptiles is performed by the colon. Fish diffuse their nitrogenous waste through the gills. Saltwater fish lose water

Explanation:
Classification of 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.
Classification of Lizard: Lizard are widespread group of squatters reptiles with over 60,000 species ....This classification is rarely used today because Sauria so defined is a paraphyletic group .
