Batrachoididae
Batrachoididae is the only family in the ray-finned fish order Batrachoidiformes . Members of this family are usually called toadfish or frogfish: both the English common name and scientific name refer to their toad-like appearance (''batrakhos'' is Greek for frog). Toadfish are benthic ambush predators that favor sandy or muddy substrates where their cryptic coloration helps them avoid detection by their prey. Toadfish are well known for their ability to "sing", males in particular using the swim bladder as a sound-production device used to attract mates. Evolution Toadfish are among the most basal percomorph orders, and are thought to have diverged from their closest relatives in the Late Cretaceous. The earliest known toadfish is likely '' Bacchiaichthys'' from the Late Cretaceous (Maastrichtian) of Italy, which very closely resembles modern toadfish and is one of the earliest known percomorphs. Its status as a toadfish has been disputed, as it is noted to have some tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Smith (ichthyologist)
James Leonard Brierley Smith (26 September 1897 – 8 January 1968) was a South African ichthyologist, organic chemist, and university professor. He was the first to identify a taxidermied fish as a coelacanth, at the time thought to be long extinct. Early life Born in Graaff-Reinet, 26 September 1897, Smith was the elder of two sons of Joseph Smith and his wife, Emily Ann Beck. Educated at country schools at Noupoort, De Aar, and Aliwal North, he finally matriculated in 1914 from the Diocesan College, Rondebosch. He obtained a Bachelor of Arts degree in chemistry from the University of the Cape of Good Hope in 1916 and a Master of Science degree in chemistry at Stellenbosch University in 1918. Smith went to the United Kingdom, where he received his PhD at Cambridge University in 1922. After returning to South Africa, he became senior lecturer and later an associate professor of organic chemistry at Rhodes University in Grahamstown. From 1922 to 1937, he was married to He ...

Keppel Harcourt Barnard
Keppel Harcourt Barnard (31 March 1887 – 22 September 1964) was a South African zoologist and museum director. He was the only son of Harcourt George Barnard, a solicitor from Lambeth, and Anne Elizabeth Porter of Royston. Life and career Barnard was born in London. His first education was at a private school in Camberley from where he went to the Realgymnasium in Mannheim to improve his German. From 1905 to 1908 this unusually gifted and versatile scholar attended Christ's College, Cambridge, taking the Natural Sciences Tripos in Botany, Geology and Zoology. He also took the newly introduced courses in Anthropology, Ethnology and Geography. For the following three years he studied law at the Middle Temple, becoming a barrister in 1911. After a short spell as naturalist with the Marine Biological Laboratory in Plymouth, he joined the staff of the South African Museum in Cape Town in 1911 as a marine biology assistant. He became assistant director in 1921 and director fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.
