Maximum depth from Ref. 83943. This is an oceanic epiplanktonic species (Ref. 3702). Particularly found in epipelagic and mesopelagic depths (Ref. 83943). Also neritic (Ref. 116105). 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
परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | 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).
