Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Aves. What are the Characteristics of the Kingdom Animalia Kingdom : Animalia or Animal Kingdom These organisms are multicellular, eukaryotic and without chlorophyll. General Characteristics of Class Reptilia: Some of the general characters of class Reptilia are listed below: 1. The respiration takes place with the help of the lungs. They are easily separated from other amniotes by having a temporal fenestra, an opening low in the skull roof behind each eye, leaving a bony arch beneath each; this accounts for their name. Marine reptiles are divided into several orders: Testudines: Turtles. 6. Organisms in class Reptilia share the characteristic of breathing with lungs at all stages of their life. Aves. It was first developed in 1676 by John Ray and Francis Willughby, but the current system was devised by Carolus Linnaeus in 1758. The class of Aves is composed of birds. Snakes are an exception. An example is the marine iguana. Asexual reproduction does not include a partner, while sexual reproduction does. (a) Protista includes unicellular eukaryotic organisms. Turtles, tortoises, and terrapins belong to this group. The reptiles are classified mainly on the structure of their skulls, in which there are temporal vacuities or fossae or empty spaces in the temporal region. Sea turtles are an example of turtles that live in the marine environment. There are almost 10,000 species of reptiles on the planet lumped into a single class known as Reptilia. Sea snakes are all venomous, but they rarely bite humans. Usually, animals are grouped together in classes or families due to certain shared characteristics. 2) The skin has a few cutaneous glands and high levels of keratin, which prevents water loss through the skin. The Class Reptilia, or reptiles, traditionally included a diverse group of animals: turtles, snakes, lizards and crocodiles, alligators, and caimans. The cells possess no cell walls and plastids.

Aves is a class in the subphylum Vertebrata of the phylum Chordata and consist of bipedal, feathered and warm blooded animals. They are vertebrates, which puts them in the same phylum as humans, dogs, cats, fish and many other animals. They are ectothermic (cold-blooded) and are found mostly in the warmer parts of the world. Required fields are marked *. The major groups of living reptiles are turtles, tuatara, lizards, snakes, and crocodiles. Class REPTILIA The upper part of the skull of reptiles is modified giving the reptiles a far more efficient and powerful jaw action and making the skull light. These are divided into two major groups- Archosauria and Lepidosauria. Orders crocodilia Chelonia and squamata all have marine species. their brain is very smooth compared to a dolphin’s. Members of the class Reptilia all share numerous characteristics (called synapomorphies) of physiology, behavior, and functional morphology that readily set them apart from amphibians, mammals, turtles, tuataras, and birds.

Mostly bear their young in eggs, which are protected by an amniotic membrane (so reptiles are referred to as "amniotes"). In this level, organisms share some common properties and are then grouped in classes according to some differences. General Characteristics of Class Reptilia 2. Characteristics of Class Reptilia. No. Question 2: What is the primary characteristic on which the first division of organisms is made? F rom the biological classification perspective, animals belong to the kingdom called Animalia.They are eukaryotes and multi-cellular living organisms. ADVERTISEMENTS: Characteristics of Class Mammalia are given below: 1) Warm blooded. Use the Venn diagram to compare and contrast the definitions of the Linnaean class Reptilia and the clade Reptilia. The skin is smooth and rough without any scales, but with glands that make it moist. It is useful to not only students but also teachers. Few of these shed the scales on their skin as skin cast. 2) Possess hair which is made of keratin. Reclassifying reptiles has been among the key aims of phylogenetic nomenclature. Reptiles are the creeping and burrowing cold blooded vertebrates bearing epidermal scales. The term Sauropsida had from the mid 20th century been used to denote all species not on the synapsid side after the synapsid/sauropsid split, a branch-based clade. In options (b), (c) and (d) the characteristics belong to the classes Amphibia, Osteichthyes and Chondrichthyes respectively. Why Did Crocodiles Survive the K/T Extinction? Characteristics of Aves.
