Information: - Doridoidea, commonly known as dorid nudibranchs (and previously known as the taxon Cryptobranchia), are a taxonomic superfamily of medium to large, shell-less sea slugs, marine gastropod mollusks in the clade Doridacea, included in the clade Nudibranchia. - The Chromodorididae , or chromodorids , are a taxonomic family of colorful , sea slugs ; dorid nudibranchs , marine gastropod mollusks in the superfamily Doridoidea . '' Chromodorid nudibranchs are among the most gorgeously colored of all animals . '' The over 360 described species are primarily found in tropical and subtropical waters , as members of coral reef communities , specifically associated with their sponge prey . The chromodorids are the most speciose family of opisthobranchs . They range in size from < 1mm to over 30 cm , although most species are approximately 2 - 3 cm in size . Although , they have a worldwide distribution , most species are found in the Indo - Pacific region . A scientific paper published in 2007 , found the most widespread chromodorid genera , ( Mexichromis , Chromodoris , Glossodoris and Hypselodoris ) to be paraphyletic or polyphyletic . The family Cadlinidae Bergh , 1891 has been considered a synonym of the Chromodorididae . Research by R.F. Johnson in 2011 has shown that Cadlina does not belong to the family Chromodorididae . She has therefore brought back the name Cadlinidae from synonymy with Chromodorididae . The chromodorid nudibranchs without Cadlina are now monophyletic and turn out to be a possible sister to the family Actinocyclidae . Cadlina and Aldisa are the only two genera currently classified in the Cadlinidae . A comprehensive phylogeny of the chromodorid nudibranchs found every one of the 14 traditional chromodorid genera were either non-monophyletic , or rendered another genus paraphyletic . Additionally , both the monotypic genera Verconia and Diversidoris are nested within clades . The authors presented a new classification of the chromodorid nudibranchs , which used molecular data to untangle evolutionary relationships and at the same time retains a historical connection to traditional systematics by using generic names attached to type species as clade names . All Chromodorid nudibranchs feed on sponges . - Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc. The word "slug" is also often used as part of the common name of any gastropod mollusc that has no shell, a very reduced shell, or only a small internal shell, particularly sea slugs and semislugs (this is in contrast to the common name "snail", which applies to gastropods that have a coiled shell large enough that the animal can fully retract its soft parts into the shell). - Doridacea is a taxonomic grouping of dorid nudibranchs, shell-less marine gastropod mollusks. included in the clade Euctenidiacea of the clade Nudibranchia. What entity does 'chromodorididae' has the relation 'parent taxon' with?
Ans: nudibranchia

Information: - The ICF Canoe Slalom World Championships are an international event in canoeing organized by the International Canoe Federation. The World Championships have taken place every year in non-Summer Olympic years since 2002. From 1949 to 1999, they had taken place in odd-numbered years. Prior to November 2008, canoe slalom was known as whitewater slalom. - Canoeing is a sport or recreational activity which involves paddling a canoe with a single-bladed paddle. In some parts of Europe canoeing refers to both canoeing and kayaking, with a canoe being called an "Open canoe". some people call them "Canadian Canoes" but Canada wasn't the only country to invent "The Canoe" - Charles Dussuet is a retired Swiss slalom canoeist who competed from the late 1940s to the early 1960s . He won nine medals at the ICF Canoe Slalom World Championships with three golds ( C - 1 : 1951 , 1953 ; C - 2 : 1953 ) , three silvers ( C - 1 team : 1953 ; C - 2 team : 1953 , 1957 ) and three bronzes ( C - 2 team : 1951 , 1959 , 1961 ) . - The International Canoe Federation (ICF) is the umbrella organization of all national canoe organizations worldwide. It is headquartered in Lausanne, Switzerland, and administers all aspects of canoe sport worldwide. 157 countries are affiliated with the ICF after seven national federations were added at the 2008 ICF Congress in Rome. What entity does 'charles dussuet' has the relation 'country of citizenship' with?
