Morphology and mode of life of the Bivalves …
WebAll bivalves are aquatic, requiring water for reproductive processes, respiration, and typically for feeding. They range in depth from the intertidal zone to the deep sea; one supratidal species (Enigmonia) lives in the tidal spray on mangrove leaves or seawalls in Australia, achieving the most "terrestrial" life-mode of any bivalve. Several ... WebBivalves being filter feeders, DNB has been proposed to spread via filtration of seawater contaminated with neoplastic cells. Since hemocytes from leukemic bivalves can survive in seawater for >6 h, currents have been suggested to be the potential environmental vectors facilitating the colonization of novel bivalve beds (Metzger et al., 2015). WebBivalve - Mode of Life - Deep Burrowing. Large pallial sinus - Long siphons to reach surface Streamlined shell - Easier burrowing - could go up and down as tide comes in and out Small muscles scars - Don't need to close valves in deep burrow Gape on shell - Can't retreat siphons or foot - would burrow to escape predators. how to stop auto program start
