Edgard Hérouard
Edgard Joseph Émile Hérouard (18 March 1858 in Saint-Quentin, Aisne - 22 March 1932 in Paris) was a French marine biologist. In 1889 he started work as a préparateur at the University of Paris, Sorbonne, earning his doctorate in natural sciences during the following year. From 1895 he served as ''chef des travaux pratiques de zoologie''. In 1901 he was named vice-president of the Société zoologique de France, and soon afterwards was appointed assistant director of the Station biologique de Roscoff. In 1910 he attained the title of associate professor, becoming a professor "without chair" in 1921. Hérouard is known for his investigations of sea cucumbers, providing descriptions of numerous Holothurian species. Also, with Yves Delage (1854-1920), he is credited with describing the Order (biology), Order Hymenostome, Hymenostomatida (1896).

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Sea Cucumber
Sea cucumbers are echinoderms from the class (biology), class Holothuroidea ( ). They are benthic marine animals found on the sea floor worldwide, and the number of known holothuroid species worldwide is about 1,786, with the greatest number being in the Asia–Pacific region. Sea cucumbers serve a useful role in the marine ecosystem as detritivores who help recycle nutrients, breaking down detritus and other organic matter, after which microbes can continue the decomposition process. Sea cucumbers have a leathery skin and an elongated body containing a single, branched gonad, are named for their overall resemblance to the fruit of the cucumber plant. Like all echinoderms, sea cucumbers have a calcified dermal endoskeleton, which is usually reduced to isolated microscopic ossicle (echinoderm), ossicles (or sclerietes) joined by connective tissue. In some species these can sometimes be enlarged to flattened plates, forming an armoured cuticle. In some abyssal or pelagic species s ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Elpidiidae
Elpidiidae is a family of deep-sea sea cucumbers. They have a translucent body with long and stout podia acting like legs. The mouth is surrounded by thick and short oral tentacles, and the dorsal part often shows pairs of elongated podia as well, pointing upwards. Some species can also show swimming appendages on top of the mouth. Sea pigs live in the darkest parts of the ocean. When introduced to warm waters, their bodies disintegrate, making them vulnerable to sudden heat changes. Genera The following genera are recognised in the family Elpidiidae: *''Achlyonice'' Théel, 1879 *''Amperima'' Pawson, 1965 *''Ellipinion'' Hérouard, 1923 *''Elpidia'' Théel, 1876 *''Irpa (genus), Irpa'' Danielssen & Koren, 1878 *''Kolga (genus), Kolga'' Danielssen & Koren, 1879 *''Peniagone'' Théel, 1882 *''Penilpidia'' Gebruk, 1988 *''Protelpidia'' Gebruk, 1983 *''Psychrelpidia'' Hérouard, 1923 *''Psychroplanes'' Gebruk, 1988 *''Rhipidothuria'' Hérouard, 1901 *''Scotoplanes'' Théel, 1882 ...
