In this article, we will address Glypheidea from a comprehensive and detailed perspective, in order to provide our readers with a complete and enriching vision on this topic. Along these lines, we will explore different facets, studies and opinions related to Glypheidea, with the aim of offering a global and updated analysis. From its origin to its current evolution, through its impact on society and its relevance in different areas, this article seeks to be an enriching source of knowledge for all those interested in entering the world of Glypheidea.
Glypheidea is an infraorder of lobster-like decapodcrustaceans, comprising a number of fossil forms and the two extant (living) generaNeoglyphea and Laurentaeglyphea:[1] The infraorder was thought to be extinct until a living species, Neoglyphea inopinata, was discovered in 1975. They are now considered "living fossils", with over 256 fossil species discovered, and just two extant species.[2]
Phylogeny
Glypheidea belongs to the cladeReptantia within the orderDecapoda, although its exact placement within Reptantia is difficult to determine.[3] Some phylogenetic studies consider Glypheidea to be most closely related to the infraorder Astacidea, which consists of the lobsters and crayfish,[2] whereas other studies instead consider Glypheidea to be more closely related to the infraorder Polychelida, a group of deep-sea blind lobsters.[3]
