Behavior And Reproduction
There is very little information on behavior and reproduction. Younger animals live with other plankton in the upper layers of the ocean, while adults live and breed in deeper waters. The light-producing eyestalks may be used to attract or locate mates.
The larvae (LAR-vee) molt, or shed their exoskeletons, up to 13 times before reaching the postlarval stage. Postlarvae resemble the adult in shape and behavior, but are not able to reproduce. The number of larval stages varies from region to region and among individuals living in the same place.
Nothing is known about their mating habits. The eggs pass from openings at the bases of the sixth pair of thoracic limbs into the brood chamber underneath the thorax. It is likely that they are fertilized in the chamber. The developing eggs probably remain in the chamber until they hatch. Hatchlings probably escape through the gap created when the female loosens or removes her ribbonlike pleopods.
