Family of marine worms

Eukrohniidae Scientific classification Kingdom: Animalia Phylum: Chaetognatha Class: Sagittoidea Order: Phragmophora Family: Eukrohniidae Tokioka, 1965[1] Genus: Eukrohnia von Ritter-Záhony, 1909

**Eukrohniidae** is a [family](/source/Family_(taxonomy)) of [sagittoideans](/source/Sagittoidea) in the [order](/source/Order_(biology)) [Phragmophora](/source/Phragmophora). It consists of a single genus, ***Eukrohnia*** von Ritter-Záhony, 1909.[2]

## History

The first species of Eukrohniidae, *Eukrohnia hamata*, was identified by [Karl Möbius](/source/Karl_M%C3%B6bius) in 1875. The [genus](/source/Genus) was named *Eukrohnia* by [R. von Ritter-Záhony](https://en.wikipedia.org/w/index.php?title=Ritter-Z%C3%A1hony&action=edit&redlink=1) in 1909 after [August David Krohn](/source/August_David_Krohn). The family was named *Eukrohniidae* by [Takasi Tokioka](/source/Takasi_Tokioka) in 1965.[1] One of the species, *Eukrohnia fowleri*, is bioluminescent.[3]
