Life cycle
Analysis of stable oxygen isotope composition of otoliths has shown that Monomitopus pallidus and Monomitopus kumae undergo an ontogenetic habitat shift, spending their early life pelagically in shallower waters, before descending to the deep-sea floor where they stay for rest of their lives.[3] The larvae of these species have been reported to coil tightly and drift in the pelagic until settlement[4].
