Description The type specimen of ''Planaria kempi'' was described as being 9.5 millimeters long and two millimeters wide. It has no visible "neck". It has two small eyes, each surrounded by an unpigmented area. The backside of the species is a medium-brown color, with a pale underside. The underside has two pores, one for the mouth and one for the genitalia.Whitehouse, R. H. (1913). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planarian
Planarians (triclads) are free-living flatworms of the class Turbellaria, order Tricladida, which includes hundreds of species, found in freshwater, marine, and terrestrial habitats.pp 3., "Planarians (the popular name for the group as a whole), or triclad flatworms (the more scientific designation of the same group), are acoelomate bilaterians". Planarians are characterized by a three-branched intestine, including a single anterior and two posterior branches. Their body is populated by adult stem cells called neoblasts, which planarians use for regenerating missing body parts. Many species are able to regenerate any missing organ, which has made planarians a popular model in research of regeneration and stem cell biology. The genome sequences of several species are available, as are tools for molecular biology analysis. The order Tricladida is split into three suborders, according to their phylogenetic relationships: Maricola, Cavernicola and Continenticola. Formerly, th ...

India
India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ...

Stanley Wells Kemp
Stanley Wells Kemp, FRS (14 June 1882 – 16 May 1945) was an English marine biologist. He was born in London, the second of three sons of Stephen Kemp, a professor at the Royal Academy and Royal School of Music. As a boy he took an interest in animals, collecting water beetles and maintaining them in aquariums and was a member of the local natural history society. He studied at St Paul's School and later went to Trinity College in Dublin from where he graduated with a gold medal in 1903. He studied botany under H. H. Dixon. In 1910 he joined the Zoological and Anthropological section of the Indian Museum and when the organization was converted in 1916 to the Zoological Survey of India, he became Superintendent and took up the study of crustaceans to continue work started by James Wood-Mason and Alfred William Alcock. He spent fourteen years in India during which he published seventeen papers on the decapods in the Indian Museum. In 1918 he made a trip to Baluchistan along wi ...

Animals Described In 1913
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...
