Epipelagic species (Refs. 83943, 116365). Chaetognaths are active carnivores, feeding mostly on copepods, crustacean larvae and other chaetognaths, and occasionally on forams and fish larvae (Ref. 81541).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | 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).
