'''Eukrohniidae''' is a [[Family (taxonomy)|family]] of [[sagittoidea]]ns in the [[Order (biology)|order]] [[Phragmophora]]. It consists of a single genus, '''''Eukrohnia''''' von Ritter-Záhony, 1909.<ref name=II>von Ritter-Za'hony, R. (1909). Die Chaetognathen der Gazelle-Expedition. ''Zoologischer Anzeiger'', 34, 787–793.</ref>
==History== The first species of Eukrohniidae, ''Eukrohnia hamata'', was identified by [[Karl Möbius]] in 1875. The [[genus]] was named ''Eukrohnia'' by [[Ritter-Záhony|R. von Ritter-Záhony]] in 1909 after [[August David Krohn]]. The family was named ''Eukrohniidae'' by [[Takasi Tokioka]] in 1965.<ref name=I/> One of the species, ''Eukrohnia fowleri'', is bioluminescent.<ref>Thuesen, E. V., Goetz, F. E. & Haddock, S. H.
