Accessory nasal sac

From BugSigDB

Accessory nasal sacs are found in a variety of teleosts (Webb, 1993) and likely assist in ventilating the olfactory epithelium by transmitting pressure fluctuations associated with gill irrigation from theoral cavity to the nasal (or sensory) sac (Jakubowski,1975; Webb, 1993; Belanger et al., 2003).
