Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | Eggs | Fecundity | Larvae
Members of the phylum Chaetognatha are hermaphroditic. Mating behavior: A preliminary visual signaling behavior for species recognition is observed to prevent predation. Life cycle: Eggs directly develop into miniature adults (hatchlings).
