Before fertilization the eggs pass into the suprabranchial chamber and then into the water tubes of the gills where they are fertilized (Pennak, 1989).
Eggs are released into the water tubes of the suprabranchial cavity and are fertilized there by sperm brought in by the ventilating water currents.
la), in Liparis there is on each side a single sensory pore called the suprabranchial pore, dorsal to the external gill slit, at the posterior end of the temporal sensory line, opening from a short ossified tube.

The embryos or larvae are then raised in the mantle cavity, suprabranchial, or infrabranchial chamber of the female (Buroker 1985, Chaparro et al.
The variety of tissue junctions increases the complexity of the branchial architecture, with 'interfilamentar spaces' or 'gaps' (also suprabranchial chambers, vertical water tubes, interlamellar cavity) and 'interfilamentar pores' (also ostia, slits) through which the inhaled water passes.
In addition, endoscopic observations were made from the suprabranchial chamber of a freshwater unionid, Lampsilis anodontoides.
