Crustacean larva stop after a single copepodid stage. Once the gonads develop, there are no further moults. Chalimus (plural chalimi) is a stage of development of a copepod parasite of fish, such as the salmon louse ("Lepeophtheirus salmonis"). "Chalimus" Burmeister, 1834 is also a synonym for "Lepeophtheirus" Nordmann, 1832. The single genus in the Facetotecta, "Hansenocaris", is only known from its larvae. They were first described by Christian Andreas Victor Hensen in 1887, and named "y-nauplia" by Hans Jacob Hansen, assuming them to be the larvae of barnacles. The adults are presumed to be parasites of other animals. Crustacean larva Crustaceans may
Bar-headed goose Bar-headed goose The bar-headed goose ("Anser indicus") is a goose that breeds in Central Asia in colonies of thousands near mountain lakes and winters in South Asia, as far south as peninsular India. It lays three to eight eggs at a time in a ground nest. The grey goose genus "Anser" has no other member indigenous to the Indian region, nor any at all to the Ethiopian, Australian, or Neotropical regions. Ludwig Reichenbach placed the bar-headed goose in the monotypic genus "Eulabeia" in 1852, though John Boyd's taxonomy treats both "Eulabeia" and the genus "Chen" as subgenera of "Anser". The
