9) clarified the varied usage and ambiguity of sinus, slit and selenizone in connection with the interpreted
exhalant zone in Palaeozoic gastropods.
In the second method, samples are taken directly from the inhalant and
exhalant flow produced by the animal and particle distribution determined (e.g., InEx method of Yahel et al.
The vigorous jets, which were used only occasionally by the animals, had very similar amplitudes of mantle contraction to the escape jets that we recorded, but had an
exhalant phase that was 1.5 to 2 times longer (see Results for greater detail).
During the spawning season, females develop a long ovipositor that they use to lay eggs in the gill cavities of mussels through the mussel's
exhalant siphon.
Offrant aux passants des languettes en papier,
exhalant des senteurs agreables, ou osant, carrement, les asperger de parfum, de nombreux jeunes squattent les trottoirs du centre d'Alger, proposant des flacons remplis de fragrances, vantees en [beaucoup moins que] copie fidele [beaucoup plus grand que] a des [beaucoup moins que] griffes [beaucoup plus grand que] mondialement renommees.
They have two siphons--an inhalant siphon that they use to pull water into their bodies, and an
exhalant siphon that they use to expel water and wastes.
Taxonomically, the main characters used for identification of Porifera are: color, shape and body texture, shape of the openings of the
exhalant and inhalant channels, consistency, skeleton organization, and types and sizes of spicules (Mothes et al., 2006).
This indicates that the experiment was properly designed and water was sufficiently mixed by the 4 air stones to ensure instantaneous mixing of the
exhalant water in the whole water volume of the aquarium which is a prerequisite for using both (1) and (2).
When mature, the larvae are passed from the marsupium to the branchial canal and eliminated to the exterior through the
exhalant opening (Castellanos and Landoni, 1990).
