... is a saprophagous and bacterivorous detritivore. The adhesive secretions by these species apparently help them gather and possibly farm food while being relatively immobile in the sediments. Our observations of movement and feeding orientation in the agglutinants suggest links between form and function...

...-energy conditions, because there seemingly is no need for an animal to respond directly to the azimuth of low-energy currents. The agglutinated tube of the polychaete Diopatra cuprea , for example, typically exhibits a current-influenced orientation (Myers, 1970, 1972). The tube itself is vertical...

Deposition occurred in laminar boundary layers between the bottom and sides of the channel and ash flows passing above. The overlapping sequence of events during deposition was (1) agglutination and incipient...

... chamber was preserved. Nine encrusting taxa, evenly distributed across the nautilid shell (cementing bivalves, serpulids, sabellids, cyclostome bryozoans, and agglutinated foraminifers), were observed in and on C. perstriatum . Of these taxa, oysters are dominant. Encrusters are abundant, with a mean...

Under higher magnification, Volborthella specimens exhibit an arrangement of agglutinated grains arranged in concentric curved laminae ( Fig. 7C ). Grain orientation within the laminae is convex toward the small aperture of the cone...
