''Pelagocephalus'' is a genus of pufferfish which is from the coasts of South Africa and New Zealand. It is monotypic In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unisp ..., being represented by the single species, ''Pelagocephalus marki'', also known as the rippled blaasop. This species grows to a length of about TL.

Tetraodontidae
Tetraodontidae is a family of marine and freshwater fish in the order Tetraodontiformes. The family includes many familiar species variously called pufferfish, puffers, balloonfish, blowfish, blowers, blowies, bubblefish, globefish, swellfish, toadfish, toadies, toadle, honey toads, sugar toads, and sea squab. They are morphologically similar to the closely related porcupinefish, which have large external spines (unlike the thinner, hidden spines of the Tetraodontidae, which are only visible when the fish have puffed up). The majority of pufferfish species are toxic, with some among the most poisonous vertebrates in the world. In certain species, the internal organs, such as the liver, and sometimes the skin, contain mucus tetrodotoxin, and are highly toxic to most animals when eaten; nevertheless, the meat of some species is considered a delicacy in Japan (as 河豚, pronounced ''fugu''), Korea (as 복, ''bok'', or 복어, ''bogeo''), and China (as 河豚, ''hétún'') when ...

John Richard Paxton
John Richard Paxton (16 January 1938 – 29 October 2023) was a United States-born Australian ichthyologist, who spent most of his career at the Australian Museum. He has a particular research interest in lanternfishes (family Myctophidae) and other deep-sea fishes. Paxton is a founding member of the Australian Society for Fish Biology and received the society's K. Radway Allen Award in 1997. Early life John Richard Paxton was born in 1938 and grew up in Los Angeles, California. He completed his undergraduate and postgraduate studies at the University of Southern California, beginning with a BA in Zoology (1960) and an MSc in Biology (1965). His master's research investigated the ecology and vertical distribution of lanternfishes (family Myctophidae) in a deep-sea basin off southern California. Paxton completed his PhD under supervisor Jay Savage, on the osteology and evolutionary history of lanternfishes, and graduated in 1968. Career Paxton spent most of his career a ...

Margaret Mary Smith
Margaret Mary Smith (née MacDonald; 26 September 1916 in Indwe, Cape Province, South Africa – 8 September 1987), was an ichthyologist, accomplished fish illustrator, and an academic. Early life Margaret Mary Smith was the daughter of Chisholm MacDonald and Helen Evelyn Zondagh. Her father was a medical doctor and her mother a descendant of the Voortrekker leader Jacobus Johannes Uys. She was the youngest of three children. Margaret attended Indwe High School. She was head girl and head scholar as well as chairperson of the debating society and captain of the netball and tennis teams. From 1934 to 1936 she attended Rhodes University, where she achieved a Bachelor of Science degree majoring in physics and chemistry. She also attended the Grahamstown Training College School of Music and obtained her University Teachers' Licentiate in Music for singing in 1936. Career In 1937, after she obtained her degree, she was hired as a senior demonstrator in chemistry at Rhodes Univ ... [...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 ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology. Overall length Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes ( lampreys) and usually Elasmobranchii (shark Sharks are a group of elasmobranch cartilaginous fish characterized by ...
