seasonal receptor[PMID:23820554], Although its function remains hypothetical, it may contain sensory receptors for depth chemical detection. Other probable functions are osmoregulation ionic transport skeletal growth and tooth regeneration, although other homeostatic functions are not excluded, response to photoperiodic signals[PMID:23820554]
