Animalia

A list of the kingdom’s species Animalia
Animals are eukaryotic multicellular creatures that belong to the biological kingdom Animalia. They are also known as metazoans. Animals generally consume organic matter, breathe oxygen, can move, reproduce sexually, and during embryonic development, the blastula, a hollow sphere of cells, becomes the body of the embryo. A total of more than 7 million animal species are thought to exist, however more over 1.5 million live animal species, including around 1 million insect species, have been identified. From 8.5 micrometres (0.00033 in) to 33.6 metres (110 ft), animals can vary in length. They construct intricate food webs through their complicated interactions with one another and their surroundings. Zoology is the study of animals from a scientific perspective.
The Bilateria, a group with members who have a bilaterally symmetrical body design, contains the majority of extant animal species. Protostomes, which include invertebrates like nematodes, arthropods, and mollusks, and deuterostomes, which comprise echinoderms and chordates—the latter of which includes vertebrates—are among the bilateria. The Upper Precambrian Ediacaran biota included creatures that have been referred regarded be primordial animals. The Cambrian boom, which started around 542 million years ago, resulted in the fossilisation of many extant animal phyla as marine animals. There are 6,331 gene families that are shared by all living things. They could have shared a 650 million-year-old progenitor, according to certain theories.

Aristotle distinguished between blooded and non-blooded creatures in antiquity. The first biological taxonomy of animals was developed by Carl Linnaeus.Jean-Baptiste Lamarck created 14 phyla with his Systema Naturae in 1809 after he published it in 1758. Single-celled creatures are no longer regarded as members of the animal kingdom because of Ernst Haeckel’s division of the animal world into multicellular metazoans (now known as Proteolia). Modern methods, such molecular phylogenetics, which are adept at uncovering evolutionary links between species, are used to classify animals biologically.

Numerous animal species are used by humans as pets, labour animals, food (including meat, milk, and eggs), materials (such as leather and wool), and transportation. Numerous land and aquatic creatures were hunted for sport, along with dogs and raptor birds. Non-human animals have been portrayed in works of art from the beginning of time.

Vertebrata

Species of the Vertebrata subphylum listed
All species of mammals, birds, reptiles, amphibians, and fish are considered vertebrates, as are all other animal species that belong to the subphylum Vertebrata (chordates having a backbone). With roughly 69,963 species currently known, the bulk of the Chordata phylum’s species are vertebrates.
Hagfish and lampreys are among the fish without jaws.
vertebrae in the jaw, such as:
Sharks, rays, and ratfish are cartilaginous fish.
skeletal vertebrae, such as:
The majority of living dwarf fish have ray fins.
Coelacanths and lungfish are two species that have lobe-fins.
Vertebrate tetrapods
The smallest vertebrate species, Paedophryne amauensis, is 7.7 mm (0.30 in) long, while the largest, the blue whale, is 33 metres (108 feet) long.Vertebrates make up less than 5% of all animal species currently known. Others lack a vertebral column and are classified as invertebrates.
The hagfish, which has improper vertebrae owing to evolutionary damage yet has them in its close cousins the lamprey, is typically considered a vertebrate. Hagfish, however, have a skull.For this reason, the vertebrate subphylum is sometimes referred to as “Crinata” when discussing morphology.
Hagfish are believed to be more closely related to lampreys than to other vertebrates in a monophyletic sense, according to molecular studies conducted since 1992. Others view them as a branch of the vertebrate taxon known as the Craniata.

Reptilia

A list of the class’s species Reptilia
The term “reptile” refers to any animal belonging to the order Reptilia, which is a paraphyletic group that contains all sauropsid amniotes with the exception of Aves (birds). Turtles, crocodiles, squamates (lizards and snakes), and rhynchocephalians (tuatara) are examples of living reptiles. In the traditional Linnaean classification system, birds are seen as belonging to a distinct class than reptiles. Since birds are now included in the Reptilia clade in contemporary cladistic classification methods, the name “Reptilia” has been redefined as a clade. Crocodiles, on the other hand, are more closely linked to birds than to any other extant reptile. In other cladistic definitions, the word “reptile” is entirely dropped in favour of the clade Sorpsida, which includes all creatures that are more closely related to contemporary reptiles than to mammals. Herpetology is the study of conventional reptile orders in combination with contemporary amphibians.
About 312 million years ago, during the Carboniferous period, the earliest known proto-reptiles emerged from sophisticated reptilian tetrapods that swiftly adapted to life on land. Halonomus, a little creature that seemed to be a lizard on the surface, was the first eureptile (also known as a “true reptile”). The two greatest reptile lineages, Archosauromorpha (crocodiles, birds, and relatives), and Lepidosauromorpha (lizards and relatives), split near the end of the Permian epoch, according to genetic and fossil evidence. Along with extant reptiles, there are several more different groups that have gone extinct, some of them as a result of major extinctions. Pterosaurs, plesiosaurs, and all non-avian dinosaurs were specifically exterminated during the Cretaceous-Paleogene extinction event, along with several species of crocodyliforms and squamates (such as mosasaurs). Non-avian reptiles exist now on every continent Tetrapod vertebrates, or animals with four limbs or descended from animals with four limbs, include reptiles. Reptiles don’t have an aquatic larval stage as amphibians do. The majority of reptiles are oviparous, while certain squamate species as well as several extinct aquatic clades are viviparous. This means that the embryo grows within the mother via the placenta (a non-mammalian organ), rather than staying inside the eggshell. happened Reptilian eggs are appropriate for reproduction on land because, like amniotes, they are encased in transport and protective membranes. Many viviparous animals provide first assistance to their babies and nourish their foetuses through diverse varieties of mammalian placenta. Sphaerodactylus ariasae, a little gecko, may grow to a maximum size of 17 millimetres (0.7 in), whereas Crocodylus porosus, a saltwater crocodile, can grow to a maximum size of 6 metres (20 feet).

Varanidae

Varanus

Species of the genus Varanus listed
Large lizards of the genus Varanus are known as monitor lizards. They are indigenous to Africa, Asia, and Oceania, and one species is even present in the Americas as an invading species. There are over 80 recognised species.

Long necks, strong tails and claws, and well-developed limbs are characteristics of monitor lizards. Although the extinct monitor lizard Magellania (Varanus persix) is capable of this, adult lengths of current species range from 20 cm (7.9 in) in certain species to more than In the case of the Komodo dragon, 3 m (10 ft). May be. reaching a length of more than 7 metres (23 feet). Although aquatic and semi-aquatic monitor species are also known, terrestrial monitors predominate. Despite the fact that most monitor lizards are carnivores, some , tiny reptiles, fish, birds, insects, and small mammals. Depending on where they dwell, some may consume fruits and vegetation.

The species’ geographic distribution includes Africa, the Indian subcontinent, China, southern Southeast Asia, Thailand, Malaysia, Brunei, Indonesia, the Philippines, New Guinea, Australia, and the Ryukyu Islands of southern Japan. islands comprised. the South China Sea and the ocean. Southern Florida and Singapore are currently home to the West African Nile monitor (Varanus stellatus). During the Neogene, monitor lizards also emerged in Europe; the final known specimens date from the Middle Pleistocene.
