Lungfishes, like tetrapods, possess a vomeronasal system [PDF]
Frontiers in Neuroanatomy, 2010 The vomeronasal system (VNS) is an accessory olfactory system that in tetrapod vertebrates is composed of specific receptor neurons in the nasal organ and a set of centers in the forebrain that receive and relay the information consecutively towards the hypothalamus.

Journal of Anatomy, EarlyView.Lungfish possess a lamellar OE and a primitive VNO called as a recess epithelium (RecE). Among the lungfish V2Rs expressed in both the lamellar OE and the RecE in small individuals, some became restricted to the RecE in large individuals. These results suggest functional separation between the lamellar OE and the RecE is still incomplete in juveniles ...

Respiratory Properties of Blood and Pattern of Gas Exchange in the Lungfish Neoceratodus forsteri (Krefft) [PDF]
, 1966 Blood respiratory properties and gas exchange patterns have been studied in the lungfish Neoceratodus. O2 - Hb dissociation curve reveals a high affinity for O2 (P50 of 11 mm Hg at PCO2 3.5 mm Hg).
