An African bush elephant (Loxodonta africana), is an example of charismatic megafauna. Charismatic megafauna are animal species that are large—in the category that they represent [1] —with symbolic value or widespread popular appeal, and are often used by environmental activists to gain public support for environmentalist goals.

In conservation biology, a flagship species is a species chosen to raise support for biodiversity conservation in a given place or social context. Definitions have varied, but they have tended to focus on the strategic goals and the socio-economic nature of the concept, to support the marketing of a conservation effort.
During the Late Pleistocene, particularly from around 50,000 years ago onwards, most large mammal species became extinct, including 80% of all mammals greater than 1,000 kilograms (2,200 lb), while small animals were largely unaffected. This pronouncedly size-biased extinction is otherwise unprecedented in the geological record.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
The hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown. A species (pl.: species) is a population of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. [1]
Of the animals removed from the wild to be sold, very few survive during capture and transport, and those that do often die from poor conditions of captivity, poor diet, and stress. Measures taken to conserve the habitats of some high-profile charismatic species have also protected many of the less charismatic species living in the same ecosystems.
His works implemented a standardized binomial naming system for animal and plant species, [51] which proved to be an elegant solution to a chaotic and disorganized taxonomic literature. He not only introduced the standard of class, order, genus, and species, but also made it possible to identify plants and animals from his book, by using the ...
The species with an EDGE score of 20 or higher are the mountain pygmy possum (25.1) and aye-aye (20.1). Only mammals have and EDGE score of 8 or higher. The non-mammal species with the highest EDGE score is the largetooth sawfish (7.4). The species with the highest ED scores are the pig-nosed turtle (149.7) and the narrow sawfish (125.1).
