A research scholar identified a new animal in his locality . how can he identified and classify the animal ?
Answers
Answer:
animals, as they do the plants, on the basis of shared physical characteristics. They place them in a hierarchy of groupings, beginning with the kingdom animalia and proceeding through phyla, classes, orders, families, genera and species. The animal kingdom, similar to the plant kingdom, comprises groups of phyla; a phylum (singular for phyla) includes groups of classes; a class, groups of orders; an order, groups of families; a family, groups of genera; and a genus (singular of genera), groups of species. As established by Linnaeus, the scientists call an animal species, as they do a plant species, by the name of the genus, capitalized, and the species, uncapitalized. So far, the scientists have classified and named something over a million animal species. Without doubt, they have millions more to go
Animal Populations
Worldwide, the animal population consists of species numbering somewhere in the millions. The largest, the blue whale, may exceed 100 feet in length and 150 tons in weight. The smallest known animals, for instance, a parasitic wasp that taxonomists have named Dicopomorpha echmepterygis, measure no more than a few thousands of an inch in length.
The most abundant and diverse animal communities occupy earth’s most biologically productive regions, for example, the tropical rainforests, where the species of living organisms probably number in the millions. Conversely, the least abundant and diverse animal communities live in the least biologically productive regions, in particular, deserts like those of our Southwest, where the species of living organisms likely number in the tens to hundreds of thousands.

Classifying an Invertebrate
At the phylum level, the monarch belongs to the arthropods, which share several physical characteristics. According to Barbara Terkanian, “A Vertebrate Looks At Arthropods,” A Natural History of the Sonoran Desert, the arthropods have jointed legs, and they have external skeletons, or exoskeletal material, that includes “eyes, mouthparts, antennae, body, legs, the fore and hind sections of the digestive tract, and some respiratory surfaces. Regions of flexible, unhardened exoskeleton serve as joints between neighboring segments.” The body cavity contains the digestive, circulatory, nervous and reproductive systems.
. In summary, it fits into the Linnaeus classification scheme as follows:
