The name "anglerfish" derives from the species' characteristic method of predation. Anglerfish typically have at least one long filament sprouting from the middle of their heads, termed the illicium. The illicium is the detached and modified first three spines of the anterior dorsal fin. In most anglerfish species, the longest filament is the ...
Phylogeography takes a population genetics and phylogenetic perspective on biogeography. In the mid-1970s, population genetic analyses turned to mitochondrial markers. [6] The advent of the polymerase chain reaction (PCR), the process where millions of copies of a DNA segment can be replicated, was crucial in the development of phylogeography.
e. In biology, phylogenetics (/ ˌfaɪloʊdʒəˈnɛtɪks, - lə -/) [1][2][3] is the study of the evolutionary history of life using genetics, which known as phylogenetic inference. It establishes the relationship between organisms with the empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology.
Phylogenesis. Phylogenetic divergence (Phyletic gradualism) (above) shows relatively slow changes during geologic epoch: the broken balance (below) illustrates morphological stability and (rarely) the relatively rapid evolutionary change. Phylogenesis (from Greek φῦλον phylon "tribe" + γένεσις genesis "origin") is the biological ...
Phylogenomics. Phylogenomics is the intersection of the fields of evolution and genomics. [1] The term has been used in multiple ways to refer to analysis that involves genome data and evolutionary reconstructions. [2] It is a group of techniques within the larger fields of phylogenetics and genomics. Phylogenomics draws information by ...
Ceratiidae. Ceratiidae, the warty sea devils, caruncled seadevils or seadevils, are a family of marine ray-finned fishes belonging to the suborder Ceratioidei, the deep-sea anglerfishes, in the anglerfish order Lophiiformes. The warty sea devils are sexually dimorphic with the small males being obligate sexual parasites of the much larger females.
Lophius. Members of the genus Lophius, also sometimes called monkfish, fishing-frogs, frog-fish, and sea-devils, are various species of lophiid anglerfishes found in the Atlantic and Indian Oceans. Lophius is known as the "monk" or "monkfish" to the North Sea and North Atlantic fishermen, a name which also belongs to Squatina squatina, the ...
Ogcocephalidae. Ogcocephalidae is a family of anglerfish specifically adapted for a benthic lifestyle of crawling about on the seafloor. Ogcocephalid anglerfish are sometimes referred to as batfishes, [1][2] deep-sea batfishes, [3] handfishes, and seabats. [4] They are found in tropical and subtropical oceans worldwide. [2]
