Namyhplana is a genus of marine flatworm belonging to the family Euplanidae. It is monotypic, containing the sole species Namyhplana henriettae. [1] It is found within Chile.
The genus Namyhplana is distinguished from other Euplanidae by the pharynx being anterior to the mid-body, the presence of cerebral, pre-cerebral and anterior marginal eye spots, a penis papilla, lacking any stylet, horizontally placed on the male copulatory apparatus, and a Lang's vesicle on the female apparatus. [2]
N. henriettae has a ribbon-like body shape that can reach up to 25 mm in length. The dorsum is light brown, with two dark brown longitudinal bands. The ventral side of the body is beige. Additional distinguishing factors include an absence of tentacles, a pharynx with few folds, independent gonopores, and a curled vagina. [2]
Both the generic and specific names of Namyhplana henriettae are given in honor of Libbie Hyman. The first part of Namyhplana, "Namyh", is an anagram of "Hyman", while henriettae is taken from Hyman's middle name, Henrietta. [2]
The gastrotrichs, commonly referred to as hairybellies or hairybacks, are a group of microscopic (0.06-3.0 mm), cylindrical, acoelomate animals, and are widely distributed and abundant in freshwater and marine environments. They are mostly benthic and live within the periphyton, the layer of tiny organisms and detritus that is found on the seabed and the beds of other water bodies. The majority live on and between particles of sediment or on other submerged surfaces, but a few species are terrestrial and live on land in the film of water surrounding grains of soil. Gastrotrichs are divided into two orders, the Macrodasyida which are marine, and the Chaetonotida, some of which are marine and some freshwater. Nearly 800 species of gastrotrich have been described.
The Polycladida represents a highly diverse clade of free-living marine flatworms. They are known from the littoral to the sublittoral zone, and many species are common from coral reefs. Only a few species are found in freshwater habitats.
The pharynx is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea. 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.
Pseudunela cornuta is a species of minute sea slug, an acochlidian, a shell-less marine and temporarily brackish gastropod mollusk in the family Pseudunelidae. Adults are about 3 mm long and live in the spaces between sand grains.
