The effects of velocity and seston concentration on the exhalant siphon area, valve gape and filtration rate of the mussel Mytilus edulis.
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.
No obvious vocal homologies are shared by these latter two taxa, but Rhinoceros Auklets may possess one vocal display (Mooing with Chucks) characterized by alternating exhalant and inhalant sounds similar to some Aethiini (Gaston and Dechesne 1996).
Preliminary data strongly suggests that ADHD children have higher rates of oxidative breakdown of omega-3 fatty acids than controls as measured by exhalant ethane levels.
Based of the ecological study of various modern brachiopods, it is now commonly accepted that brachiopods have a separated inhalant and exhalant feeding mechanism (Chuang 1956; LaBarbera 1984).
En ce debut de vingt et unieme siecle, plusieurs autochtones souhaitent tirer un trait definitif sur la Loi sur les Indiens ; la plupart des chefs veulent aussi en finir avec les tentatives du gouvernement federal de toiletter cette vieille loi exhalant l'evolutionnisme victorien.
This orientation, parallel to flow, might reduce the chance of mussels becoming dislodged and also in aiding filtering by having the inhalant siphon most upstream and exhalant most downstream (Di Maio and Corkum 1997).
By inserting the OIT into the exhalant chamber, the distal margin of the gill and the abfrontal surface of the filaments of 7 snails were also observed.
The clam Mactra veneriformis also egests feces and pseudofeces through the exhalant siphon and inhalant siphon, respectively.
The inhalant siphon transports seawater containing dissolved oxygen and suspended microalgae, which is pumped via the ciliated ctenidia (gills), whereas the exhalant siphon expels rejected food particles and pseudo feces (Feldman et al.
Exposure to the toxic alga induced a brief, incomplete shell closure and triggered valve adductions and the production of pseudofeces, which were rejected through the exhalant siphon.
ABSTRACT We evaluated the technique of measuring the exhalant siphon area (ESA) as an indicator of feeding activity in the blue mussel, Mytilus edulis.
