Chaetognatha: A list of valid familes, genera and species.

Compiled by Erik V. Thuesen, this list follows that of Robert Bieri compiled in 1991 (in Bone et al. "The Biology of Chaetognaths", Oxford University Press). I have corrected various errors in Bieri's list, and I have brought the list of chaetognath species up to date as of the year 2009. There are 127 species on this list. The type species of the genus is the first in the list and the other species are listed alphabetically. Nomenclature above the level of family is compiled on a separate page. Links to other chaetognath taxonomy lists can be found at the bottom of this page.
