<\/span>What is Amphibians Classification?<\/span><\/u><\/strong><\/span><\/h2>\n

Amphibians classification is defined as cold-blooded small vertebrate animals that can adapt in both land and water ecosystem.\u00a0<\/span><\/p>

      These animals are born in water and grow to become adults through a process called metamorphosis. They are typically living on terrestrial habitat but move to aquatic habitat for breeding.\u00a0<\/span><\/p>\n

      The amphibians live a double life as a connecting link between land and water ecosystems. For example- Frogs, toads. <\/span><\/p>\n

      The baby frog is known as a tadpole with no legs and lungs. At this stage, the tadpoles are quite similar to fishes. <\/span><\/p>\n

      They have gills to breathe in water and tail to swim like fishes. However, once they grow into adults, their tail vanishes. <\/span>Now, they are grown up and spend time both in water and land as per their wish and requirements.<\/span><\/p>\n

      Amphibian is an essential class of animal kingdom that can survive in water as well as on land. Many species come under amphibians. <\/span><\/p>\n

      Let us have an overview of the general characteristics of these animals before we start with amphibian’s lower classification.\u00a0<\/span><\/p>\n

      <\/span>General Characteristics of Amphibians<\/span><\/strong><\/span><\/h3>\n

      These are the general characteristics of amphibians. The classification of amphibians depends on these characteristics. However, some characteristics may vary from one species to another.\u00a0<\/span><\/p>\n

      • Amphibians are inhabitants of both terrestrial and sea<\/strong><\/span><\/a> habitat.<\/span><\/li>\n
      • These are cold-blooded animal species.<\/span><\/li>\n
      • Their body can divide into two parts- head and trunk. Some species may have a tail as well.<\/span><\/li>\n
      • Two pairs of limbs help them in locomotion.\u00a0<\/span><\/li>\n
      • Their skin has no scales.<\/span><\/li>\n
      • Their skin has mucous glands that help to keep them moist.<\/span><\/li>\n
      • The external ear is not present in amphibians.<\/span><\/li>\n
      • They use gills in the larval stage and lungs in the adult stage for respiration.<\/span><\/li>\n
      • Their heart has three chambers.<\/span><\/li>\n
      • The RBCs of amphibian species are biconvex and nucleated.<\/span><\/li>\n
      • They have a bony endoskeleton.<\/span><\/li>\n
      • The alimentary canal, excretory & urogenital tract of amphibians opens outside through cloaca.<\/span><\/li>\n
      • Amphibian species are generally oviparous that lay eggs.<\/span><\/li>\n
      • The development of these species consists of larval stages.\u00a0<\/span><\/li>\n<\/ul>\n

        <\/span>Amphibians Classification<\/span><\/strong><\/span><\/h3>\n

        There are approximately 6200 amphibian species that live on the planet. All the species play an essential role in the environment. As far as the classification of amphibians is concerned, they can classify into different subclasses and orders. The amphibian’s lower classification is as follows.\u00a0<\/span><\/p>\n

        Kingdom- Animalia<\/span><\/p>\n

        Phylum- Chordata<\/span><\/p>\n

        Subphylum- Vertebrata<\/span><\/p>\n

        Superclass- Tetrapoda<\/span><\/p>\n

        Class- Amphibia<\/span><\/p>\n

        <\/span>Class Amphibia<\/span><\/strong><\/span><\/h3>\n

        It refers to a double lifestyle. This class includes animals like salamanders, frogs, toads, and caecilians that cover almost 3900 species of amphibia<\/strong> class.<\/a><\/span><\/p>\n

        These species are tetrapod, that means the animals have four limbs. These limbs evolve from pectoral and pelvic fins that facilitate them moving about on land.\u00a0<\/span><\/p>\n

        The skin of amphibian class species is moist, glandular, and magid (except caecilians). The skin of caecilians has scales as fishes have. <\/span><\/p>\n

        They have unique characteristics that allow them to survive in both ecosystems (land and water) and also play an essential role in the food chain.<\/span><\/p>\n

        We start the classification of amphibians with a subclass Stegocephali.<\/span><\/p>\n
