Robert Frederick Inger
Robert Frederick Inger (September 10, 1920 – April 12, 2019) was an American herpetologist. During his lifetime, he wrote numerous books and publications about herpetology. He was also the curator for amphibians and reptiles at the Field Museum in Chicago (''City in a Garden''); I Will , image_map = , map_caption = Interactive Map of Chicago , coordinates = , coordinates_footnotes = , subdivision_type = Country , subdivision_name ..., Illinois. Family Robert Inger was the son of Jacob Inger and Anna Bourd. In 1946 he married Mary Lee Ballew (b. 1918) who died of cancer in 1985. In 1991 he married Tan Fui Lian (b. 1951). Education Inger's high school biology teacher was Julian Steyermark, who became curator of botany at the Field Museum. Steyermark was the role model that led Inger to the Field Museum to volunteer, where he was interviewed by Karl P. Schmidt, Dwight Davis, and Clifford H. Pope. As ...

Chin Phui-Kong
The chin is the forward pointed part of the anterior mandible ( mental region) below the lower lip. A fully developed human skull has a chin of between 0.7 cm and 1.1 cm. Evolution The presence of a well-developed chin is considered to be one of the morphological characteristics of ''Homo sapiens'' that differentiates them from other human ancestors such as the closely related Neanderthals. Early human ancestors have varied symphysial morphology, but none of them have a well-developed chin. The origin of the chin is traditionally associated with the anterior–posterior breadth shortening of the dental arch or tooth row; however, its general mechanical or functional advantage during feeding, developmental origin, and link with human speech, physiology, and social influence are highly debated. Functional perspectives Robinson (1913) suggests that the demand to resist masticatory stresses triggered bone thickening in the mental region of the mandible and ultimately formed a ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Pangio
''Pangio'' is a genus of small Asian freshwater fish in the true loach family Cobitidae. In earlier taxonomic schemes it was known as ''Acanthophthalmus''. The "kuhli loach" is well-known in the aquarium trade and commonly identified as ''P. kuhlii'', but most individuals actually appear to be ''P. semicincta''. The type species is ''Cobitis cinnamomea'' McClelland 1839, now known as ''Pangio pangia''. These fish are best represented in Southeast Asia where all but five of the species live, including the Greater Sunda Islands with sixteen species. The five species found outside Southeast Asia are from India and Myanmar. They inhabit a wide range of mostly calm waters such as streams, swamps (often peat swamps) and backwaters, but there are also species in fast-flowing waters, and one, ''P. bhujia'', lives underground. Species There are currently 33 recognized species in this genus: * ''Pangio agma'' ( M. E. Burridge, 1992) * ''Pangio alcoides'' Kottelat & K. K. P. Lim, 199 ...
