Libbie Hyman
Libbie Henrietta Hyman (December 6, 1888 – August 3, 1969), was a U.S. zoologist. She wrote numerous works on invertebrate zoology and the widely used '' A Laboratory Manual for Comparative Vertebrate Anatomy'' (1922, revised in 1942). Life Born in Des Moines, Iowa, she was the daughter of Joseph Hyman and Sabina ('Bena') Neumann. Hyman's father, a Polish/Russian Jew, adopted the surname when he immigrated to the United States as a youth. He successively owned clothing stores in Des Moines, in Sioux Falls, South Dakota, and in Fort Dodge, Iowa, but the family's resources were limited. Hyman attended public schools in Fort Dodge. At home she was required to do much of the housework. She enjoyed reading, especially books by Charles Dickens in her father's small den, and she took a strong interest in flowers, which she learned to classify with a copy of Asa Gray's '' Elements of Botany''. She also collected butterflies and moths and later wrote, "I believe my interest in nature i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Des Moines, Iowa
Des Moines () is the capital and the most populous city in the U.S. state of Iowa. It is also the county seat of Polk County. A small part of the city extends into Warren County. It was incorporated on September 22, 1851, as Fort Des Moines, which was shortened to "Des Moines" in 1857. It is located on, and named after, the Des Moines River, which likely was adapted from the early French name, ''Rivière des Moines,'' meaning "River of the Monks". The city's population was 214,133 as of the 2020 census. The six-county metropolitan area is ranked 83rd in terms of population in the United States with 699,292 residents according to the 2019 estimate by the United States Census Bureau, and is the largest metropolitan area fully located within the state. Des Moines is a major center of the US insurance industry and has a sizable financial services and publishing business base.

Charles Manning Child
Charles Manning Child (February 2, 1869 – December 19, 1954) was an American zoologist noted for his work on regeneration at the University of Chicago. Early life Child was born on February 2, 1869, in Ypsilanti, Michigan, to Charles Chauncy Child and Mary Elizabeth (née Manning) Child. He was the only surviving child to the couple. Growing up on a family farm in Higganum, Connecticut, Child enjoyed reading. After graduating from elementary school in 1882, Child attended Middletown High School in Middletown, Connecticut, until his graduation in 1886. Career Child was accepted to Wesleyan University in Middletown. In 1890 he graduated Wesleyan with a Bachelor of Philosophy and in 1892 he received a Master of Science degree from the same university, having served as a graduate assistant in biology at Wesleyan from 1890 to 1892. Working under Rudolf Leuckart at the University of Leipzig, Child graduated with a Doctor of Philosophy in 1894. Upon returning to the United States, h ...

Ctenophora
Ctenophora (; ctenophore ; ) comprise a phylum of marine invertebrates, commonly known as comb jellies, that inhabit sea waters worldwide. They are notable for the groups of cilia they use for swimming (commonly referred to as "combs"), and they are the largest animals to swim with the help of cilia. Depending on the species, adult ctenophores range from a few millimeters to in size. Only 100 to 150 species have been validated, and possibly another 25 have not been fully described and named. The textbook examples are cydippids with egg-shaped bodies and a pair of retractable tentacles fringed with tentilla ("little tentacles") that are covered with colloblasts, sticky cells that capture prey. Their bodies consist of a mass of jelly, with a layer two cells thick on the outside, and another lining the internal cavity. The phylum has a wide range of body forms, including the egg-shaped cydippids with retractable tentacles that capture prey, the flat generally combless plat ...

Protozoa
Protozoa (singular: protozoan or protozoon; alternative plural: protozoans) are a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris. Historically, protozoans were regarded as "one-celled animals", because they often possess animal-like behaviours, such as motility and predation, and lack a cell wall, as found in plants and many algae. When first introduced by Georg Goldfuss (originally spelled Goldfuß) in 1818, the taxon Protozoa was erected as a class within the Animalia, with the word 'protozoa' meaning "first animals". In later classification schemes it was elevated to a variety of higher ranks, including phylum, subkingdom and kingdom, and sometimes included within Protoctista or Protista. The approach of classifying Protozoa within the context of Animalia was widespread in the 19th and early 20th century, but not universal. By the 1970s, it became usual to require th ...

Hydra (genus)
''Hydra'' ( ) is a genus of small, freshwater organisms of the phylum Cnidaria and class Hydrozoa. They are native to the temperate and tropical regions. The genus was named by Linnaeus in 1758 after the Hydra, which was the many-headed beast defeated by Hercules as when the animal had a part severed, it would regenerate much like the hydra’s heads. Biologists are especially interested in ''Hydra'' because of their regenerative ability; they do not appear to die of old age, or to age at all. Morphology ''Hydra'' has a tubular, radially symmetric body up to long when extended, secured by a simple adhesive foot known as the basal disc. Gland cells in the basal disc secrete a sticky fluid that accounts for its adhesive properties. At the free end of the body is a mouth opening surrounded by one to twelve thin, mobile tentacles. Each tentacle, or cnida (plural: cnidae), is clothed with highly specialised stinging cells called cnidocytes. Cnidocytes contain specialized s ...

Turbellaria
The Turbellaria are one of the traditional sub-divisions of the phylum Platyhelminthes (flatworms), and include all the sub-groups that are not exclusively parasitic. There are about 4,500 species, which range from to large freshwater forms more than long or terrestrial species like ''Bipalium kewense'' which can reach in length. All the larger forms are flat with ribbon-like or leaf-like shapes, since their lack of respiratory system, respiratory and circulatory system, circulatory systems means that they have to rely on diffusion for internal transport of metabolites. However, many of the smaller forms are round in cross section. Most are predators, and all live in water or in moist terrestrial environments. Most forms reproduce sexual reproduction, sexually and with few exceptions all are hermaphrodites, simultaneous hermaphrodites. The Acoelomorpha and the genus ''Xenoturbella'' were formerly included in the Turbellaria, but are no longer regarded as Platyhelminthes. All th ...
