filter feeder

any MICROPHAGOUS marine or freshwater animal that creates currents, usually by ciliary action, so that food particles are carried either into the body cavity, as is the case in, for example, the sea-squirt, or across the gills where the particles are trapped in MUCUS which is carried, again by ciliary action, into the entrance to the gut system. The freshwater clam, Anodonta, is an example of the latter type of filter feeder.

Older ctenochasmids did not possess such an obvious sieving basket, but some had elongated snouts with many slender teeth, also interpreted as adaptations for filter feeding. These pterosaurs were around at the time the droppings were made, and as the footprints from the site have also been attributed to ctenochasmids it is likely that such pterosaurs produced both the droppings and the footprints.

The greatest larval growth rate was determined to occur a few days before the beginning of the ontogenetic transformation from a selective particulate feeding to omnivorous filter feeding, and during the shift from oceanic waters through the coastal boundary zone into the estuary, but there was some variability between sampling years.

These organisms thrive in shallow, sunlit waters of coral reefs and derive their nutrition by filter feeding, as well as via transfer of photosynthetic products from their symbiont, the zooxanthellae Symbiodinium sp.
