This is because the completely fused mantle and siphon of geoducks obscures the internal organs, with only the inhalant and exhalent orifices and the pedal gape open to the surrounding environment.
Also sportive activities are able to facilitate the repultion of sodium from kidneys and consequently cause the decrease of liquid content and blood pressure(31)It seems that sportive activities are able to decrease the blood pressure by increasing the number of arterioles in active skeletal muscles, exhalent increase, decrease of because of dilatability, resistance decrease against the blood flow, the improvement of bloody vessel neural regulation, decrease of environmental resistance, decrease of heart beat in activity and relaxation time [32]
We tagged blacklip abalone by inserting a plastic rivet into the open exhalent hole furthest from the shell lip.
containing phagocytes in the gill lumen, which resulted in the obstruction of the water flow between the inhalant and exhalent currents.

In the follow-up experiment to determine the possible source of this uncontrolled fertilization, it was found that a proportion of the eggs (varying between 30% and 95%) collected directly from the openings of exhalent siphons had already been fertilized.
Movements of the cephalic and epipodial tentacles, rotations of the shell, and the exhalent water current all produced fluctuations in oxygen concentrations at fixed points within the DBL.
1995), and probably detect clams by following plumes from exhalent siphons, and/or coming in contact with siphons or siphon holes while probing sediment with appendages (Dare & Edwards 1981).
