Anandroplana
''Anandroplana'' is a genus of flatworms belonging to the family Ilyplanidae. Description Members of ''Anandroplana'' were originally differentiated by Libbie Hyman; species are oval and elongate and shape, and have an encircling band of marginal eyes. The pharynx The pharynx (: pharynges) is the part of the throat behind the human mouth, mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates ... is long and ruffled, with the muscular male apparatus close behind. There is no seminal vesicle, prostatic vesicle or penis papilla.Hyman, Libbie H. 1955. "Some Polyclad Flatworms from the West Indies and Florida."

Ilyplanidae
Ilyplanidae is a family of flatworms belonging to the order Polycladida The Polycladida represents a highly diverse clade of free-living marine flatworms. They are known from the littoral to the sublittoral zone (extending to the deep hot vents), and many species are common from coral reefs. Only a few species are fo ....

Libbie Hyman
Libbie Henrietta Hyman (December 6, 1888 – August 3, 1969), was an American 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 a child of Jewish parents, Joseph and Sabina ( Neumann) Hyman. Her father, an emigrant from Poland, adopted the surname "Hyman" when he immigrated to the United States as a youth. Her mother was from Germany. Joseph Hyman 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 mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flatworms
Platyhelminthes (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") is a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates commonly called flatworms or flat worms. Being acoelomates (having no body cavity), and having no specialised circulatory and respiratory organs, they are restricted to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both ingestion (intake of nutrients) and egestion (removal of undigested wastes); as a result, the food can not be processed continuously. In traditional medicinal texts, Platyhelminthes are divided into Turbellaria, which are mostly non- parasitic animals such as planarians, and three entirely parasitic groups: Cestoda, Trematoda and Monogenea; however, since the turbellarians have since been proven not to be monophyletic, this classifica ...

Pharynx
The pharynx (: pharynges) is the part of the throat behind the human mouth, mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx. The flap of cartilage called the epiglottis stops food from entering the larynx. In humans, the pharynx is part of the Digestion, digestive system and the conducting zone of the respiratory system. (The conducting zone—which also includes the nostrils of the Human nose, nose, the larynx, trachea, bronchus, bronchi, and bronchioles—filters, warms, and moistens air and conducts it into the lungs). The human pharynx is conventionally divided into three sections: the nasopharynx, oropharynx, and laryngopharynx (hypopharynx). In humans, two sets of pharyngeal muscles form the pharynx and determine the shape of its lumen (anatomy), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhabditophora Genera
Rhabditophora (from ''rhabdito''-, rhabdite + Greek language, Greek -φορος [-''phoros''], bearer, i.e., "rhabdite bearers") is a subphylum (previously a class) of flatworms. It includes all parasite, parasitic flatworms (clade Neodermata) and most free-living species that were previously grouped in the now obsolete class Turbellaria. Therefore, it contains the majority of the species in the phylum Platyhelminthes, excluding only the Catenulida, catenulids, to which they appear to be the sister group. The clade Rhabditophora was originally erected by Ulrich Ehlers in 1985Ehlers, U. (1985) ''Phylogenetic relationships within the Platyhelminthes''. ''In'' S. Conway Morris; J. D. George; R. Gibson; H. M. Platt (Eds.), ''The origins and relationships of lower invertebrates''.
