WebThe labial palps of scallops are similar to those of the majority of bivalves, consisting of a right and left pair of tissue flaps, into which the anterior ends of the gills are inserted (Figure 3.4).The detailed structure and ultrastructure of scallop labial palps has been reported for only two species, Placopecten magellanicus and Chlamys varia (Beninger et al., 1990a). WebAlveolar ducts connect to alveolar sacs. Gas exchange between the lung and blood takes place in the alveolus. Respiratory system in fish. Remove the gills and place them in a container with water and observe. Afterwards, place the gills in another container and leave the gills exposed to air for a few minutes.

WebXylophaga spp. are the primary wood boring bivalves responsible for the degradation of wood on the ocean floor at depths of 150m to greater than 7000m. Symbiotic, nitrogen-fixing, cellulolytic bacteria have been found in the gills of two deepwater species of Xylophaga. This suggests that the roles of bacterial symbionts in providing nitrogen ... WebThe organization, general anatomy, and surface microanatomy of all regions of the gills of a representive bivalve mollusc, Placopecten magellanicus Gmelin, were studied using stereo-microscopic, histological, and scanning electron microscopic techniques. Individuals were collected in May and November 1985 from Chamcook Bay, New Brunswick, Canada.
