“…The funnel-shaped burrows of Chasmagnathus granulatus with low aspect ratio (depth/diameter < 1) exemplify a common entrance shape among burrowing species, and have been suggested to work as a sediment trap in other thalassinidean shrimps (Suchanek 1983, Poore & Suchanek 1988, Witbaard & Duineveld 1989, Vaugelas 1990, Nickell & Atkinson 1995. Our results confirm that these burrows are efficient bedload collectors.…”

“…However, based on the heuristic model proposed by Suchanek (1985), the architecture of C. granulatus burrows reflects variations in trophic modes associated with sediment structure (Iribarne et al 1997). According to this model, burrows with funnel shape entrances favor deposit feeding because they work as sediment traps by enhancing capture of bedload-transported particles that slip down the sides of the funnel (Suchanek 1983, Poore & Suchanek 1988, Witbaard & Duineveld 1989, Vaugelas 1990, Nickell & Atkinson 1995.…”

The burrowing crab Chasmagnathus granulatus is the most abundant bioturbator in estuarine intertidal sediments from southern Brazil to central Argentina. This crab is a deposit feeder that excavates and maintains large semi-permanent open burrows with funnel shaped entrances. In this study we showed that the funnel shaped burrows with low aspect ratio are the most common and, with field experiments, we demonstrated that these burrows are also the most efficient in the capture of organic matter. As shown by C isotopic signatures, the origin of trapped detrital material is Spartina densiflora. Burrows are distributed in the upper part of estuaries and saltmarshes, mostly in areas of low energy, and cover extensive areas between the marsh vegetation and the open estuary. Through sampling of crab densities and use of satellite images, we estimated the number of burrows of different shapes in the Bahia Blanca estuary (38°50' S), one of the largest estuarine intertidals in the SW Atlantic. After combining this information with the trapping efficiency of burrows of different shapes, we estimated that within 100 d, a crab bed could capture the entire annual production from a marsh area of similar size. Therefore, we suggest that these extensive burrow beds may be considered large macrodetritus retention areas, reducing the amount of organic matter exported from marshes but locally increasing the sediment organic matter content.

“…Incomplete casts made by Curran at the Bahamas (personal communication in Vaugelas, 1990) closely resemble the burrows described here and can be attributed to G. acanthochirus. A similar burrow shape have been reported for G. laurae (Vaugelas and Saint Laurent, 1984;Vaugelas, , 1990, G. motupore (Poore and Suchanek, 1988;Suchanek personal communication, 1989 andin Vaugelas, 1990) and G. armatus (Vaugelas, personal communication 1987;Vaugelas, 1990). Similar in shape are also the burrows of Callianassa sp.…”

Burrows of decapod crustaceans were investigated by in situ resin casting in various mangrove and back-reef environments. Alpheid shrimps (A. floridanus and A. heterochaelis) were the most numerous burrowing shrimps in soft muddy sediments of mangrove channels. Their burrows consist either of a single U or a series of U's inhabited by a pair of shrimp or are Y-shaped and inhabited by a single shrimp and a gobiid associate. Large mounds and deep funnels are produced by the thalassinidean Glypturus acanthochirus, both in bare sediments of mangrove channels and in back-reef subtidal sediments. Their burrows consist of a spiral with several radiating branches leading to the surface and deeper blind chambers often filled with shell particles reaching to a depth of over 160 cm. The thalassinidean Neocallichirus grandimana inhabits the intertidal of protected back-reef sands; it occupies shallow, mainly horizontal burrows. Corallianassa longiventris, characteristic of coarse sediments of the intertidal and shallow subtidal back-reef, inhabits simple J-to U-shaped burrows with blindly ending chambers in 60 to 80 cm sediment depth. Axiopsis serratifrons lives in pairs in sediments with a higher content of coral rubble; its burrows are simple, inclined, and spiral-shaped and reach a sediment depth of 30 cm.All burrows described in this paper are similar to those previously recorded for the respective species. Only the burrows of alpheids are less deep than those described from the intertidal. The burrowing activity of G. acanthochirus greatly influences grain size distribution and accumulation of large shell particles in deeper sediment layers. Burrow types reflect the systematic group to which the animals belong rather than feeding modes.

“…Surface mounds (Feature 1) are caused by removal of sediment from the burrow to the surface and, apart from during burrow construction, are indicative of a deposit feeding trophic mode. The origin of this sediment, however, can be either surface, as for some tropical callianassid species using the burrow as a sediment trap (Suchanek 1983, Poore & Suchanek 1988, Vaugelas 1990 and as speculated for C. subterranea from the North Sea (Witbaard & Duineveld 1989), or subsurface, as for C. subterranea from the present study.…”

“…Suchanek et al (1986) resin cast burrows of an unidentified callianassid species from a tropical lagoon. They suggested that the burrow was acting as a sediment trap, a hypothesis supported by other authors (Suchanek 1983, Poore & Suchanek 1988, Witbaard & Duineveld 1989, Vaugelas 1990. Particles falling or subducted into the funnel-shaped openings by animalgenerated currents may be used directly or indirectly (via the growth of micro-organisms) as food.…”

ABSTRACT-The burrow morphology and feeding behaviour of 3 species of thalassinidean shrimps, Callianassa subterranea, Jaxea noctuma and Upogebia stellata, from organically enriched sediments on the west coast of Scotland were studied using a resin casting technique and from observations in situ and in the laboratory. C, subterranea is primarily a sub-surface deposit feeder but can also supplement its diet by suspension feeding. The burrow conslsts of a lattice of tunnels and chambers connected to the surface by an inhalant and exhalant shaft and can reach depths of greater than 86 cm. J. nocturna is also a deposit feeder but uses a resuspension technique. Sub-surface material is taken but this species may also scavenge organic material from the sediment surface. The burrow is relatively persistent with a wide spiralling shape. Burrow depths in excess of 92 cm have been recorded. U. stellata is primarily a suspension feeder but has the ability to deposit and resuspension feed. Burrows comprise several connected U-and Y-shaped components and reach depths of at least 26.5 cm. These 3 thalasslnidean species exhibit a degree of plasticity in their feeding and different trophic modes can be utilized in order to exploit the most advantageous food source available. The burrow of each species is described in terms of functional morphology with respect to feeding and discussed in relation to existing models of thalassinidean burrow architecture. A new approach to thalassinidean trophic classification based on individual components of burrow morphology rather than the complete burrow is proposed.
