Thus, when clamped, molluscs first deplete the oxygen stored in their mantle cavity
water and then must either switch to anaerobic respiration (Segura et al.
Water leaves the mantle cavity
via an exhalent funnel which can be used to generate propulsion.
The parasitological analysis showed two species of copepods, Pseudomyicola spinosus and a calanoid species in the mantle cavity
and gills; additionally, a turbellarian species was also observed in the mantle cavity
, none of these symbionts were related to tissue damage.
This is pumped upwards, by regular contraction of the pedal disc, into the mantle cavity
, where organic matter is extracted.
In many gastropods the anus, gills and mantle cavity
are rotated 180 degrees.
Organs of the Mantle Cavity
: The topography of the principal mantle cavity
organs, after removal of the left valve and the left mantle is illustrated in Figure 5a, b.
across the roof of the right half of the mantle cavity
(Figs 1D, 2C, 4B).
It uses a sort of jet propulsion to pull water into the mantle cavity
of its shell and then blow it out the siphon beneath the tentacles.
The gametes are evacuated to the mantle cavity
through the right kidney opening.
To swim, the animal folds the fins around its body, draws water into the mantle cavity
, closes off the front of the cavity, and shoots the water back out through its multidirectional funnel.
With little or no foreplay, without even raising its pulse, a male will extend a specialized arm and insert it into the female's mantle cavity
antagonism of the NRM) is accomplished presumably by contraction of the transverse or circumferential muscle fibers of the muscular hydrostatic head retractor muscle, possibly in combination with the hydrostatic pressure of the mantle cavity
