“…The early observations of Watson (1895) on Panthalis and the more recent ones of Casanova & Coulon-Roso (1967) on Platynereis indicate that the production of secreted threads may be an alternative method of construction. The observations of Barnes (1964Barnes ( , 1965 on chaetopterids indicated that sections of tube were produced as a viscous fluid secretion from the ventral surface of the worm's anterior segments, were moulded to shape and then hardened in some way. Brown & McGee-Russell (1971) have shown, however, that the tube of at least one chaetopterid (Chaetopterus variopedatus) contains ordered layers of protein fibres embedded in an amorphous matrix.…”

The ‘mucous’ tube of Platynereis dumerilii is made up of successive layers of fine threads held together by an adhesive secretion. Tube construction involves a regular sequence of behaviour which can be modified if algae or other objects are available for incorporation into the tube wall. Anterior parapodia are specialized for tube construction and gland cells producing tube components occupy most of the coelom in these segments. Several types of gland cell can be recognized histologically and those which form the threadsdischarge into a complex spiral organ below the cuticle.

“…Besides the above-mentioned 'pistonpump mucus-net' feeding mode of Chaetopterus variopedatus, 5 additional species of chaetopterids use similar filter nets (Barnes, 1964(Barnes, , 1965. In some instances a single net is employed (Telepsavus costarum, Ranzanides sagittaria), but in other cases several nets are formed on successive segments (Spiochaetoptrus oculatus, Phyllochaetopterus socialis, Mesochaetopterus taylori).…”

A large number of suspension-feeding aquatic animals (e.g. bivalves, polychaetes, ascidians, bryozoans, crustaceans, sponges, echinoderms, cnidarians) have specialized in grazing on not only the 2 to 200 µm phytoplankton but frequently also the 0.5 to 2 µm free-living bacteria, or they have specialized in capturing larger prey, e.g. zooplankton organisms. We review the different particle capture mechanisms in order to illustrate the many solutions to the common problem of obtaining nourishment from a dilute suspension of microscopic food particles. Despite the many differences in morphology and living conditions, particle capture mechanisms may be divided into 2 main types. (1) Filtering or sieving (e.g. through mucus nets, stiff cilia, filter setae), which is found in passive suspension feeders that rely on external currents to bring suspended particles to the filter, and in active suspension feeders that themselves produce a feeding flow by a variety of pump systems. Here the inventiveness of nature does not lie in the capture mechanism but in the type of pump system and filter pore-size. (2) A paddle-like flow manipulating system (e.g. cilia, cirri, tentacles, hair-bearing appendages) that acts to redirect an approaching suspended particle, often along with a surrounding 'fluid parcel', to a strategic location for arrest or further transport. Examples include (1) sieving (e.g. by microvilli in sponge choanocytes, mucus nets in polychaetes, acidians, and salps among others), filter setae in crustaceans, 'ciliary sieving' by stiff laterofrontal cilia in bryozoans and phoronids; and (2) 'cirri trapping' in mussels and other bivalves with eu-laterofrontal cirri, ciliary 'catch-up' in bivalve and gastropod veliger larvae, some polychaetes, entroprocts, and cycliophores. These capture mechanisms may involve contact with a particle, and possibly mechanoreception or chemoreception, or may include redirection of particles by the interaction of multiple currents (e.g. in scallops and other bivalves without eu-laterofrontal cirri). Based on the review, we discuss the current physical and biological understanding of the capture process and suggest a number of specific problems related to particle capture, which may be solved in the future using advanced theoretical, computational and experimental techniques.

“…The polychaete family Chaetopteridae is well known for using filter nets (Barnes 1964(Barnes , 1965Sendall et al 1995). In Spiochaetopterus oculatus, Telepsavus costarum, and Phyllochaetopterus socialis, the water current through the tube is generated by ciliary rings of the foliaceous notopodia.…”

The energy cost for various ciliary filter feeders shows that useful pump work constitutes 0.3-1.1% of the total metabolic expenditure. The 'water processing potential' (liters of water pumped per milliliter O 2 consumed by the animal) is a useful tool for characterizing filter feeding and adaptation to the environment. The six types of ciliarycapture mechanisms (collar sieving, cirral trapping, ciliary sieving, ciliary downstream collecting, ciliary upstream collecting, mucus-net sieving) are reviewed as well as the aerosol/hydrosol filtration theory. A brief overview of fluid mechanical principles and tools for studying ciliary functions is given.Filter feeding (or suspension feeding) is widely represented among invertebrate taxa, and cilia-mediated feeding is particularly common in the marine environment. Ciliary filter feeders remove suspended food particles, mainly phytoplankton (2-200 m), but in many cases also free-living bacteria (0.2-2 m), from the water (Jørgensen 1966(Jørgensen , 1975Wotton 1994;Silverman et al. 1995Silverman et al. , 1997 Riisgård andLarsen 1995, 2001;Gili and Coma 1998). These animals have adapted to life in a nutritionally dilute environment, and they show great variations in particle capture mechanisms and pump design (Foster-Smith
