“…URBAN (1994) verified this relationship for Tagelus dombeii Lamarck, 1818. Elongated-shelled bivalves normally predominate in compact sediments because of their high capacity to burrow (EAGAR 1978), expending less energy (TRUEMAN 1966, STANLEY 1970. The long thin shells of deep burrowers could be an advantage because less energy is invested in shell growth (URBAN 1994).…”

The population biology and production of the stout razor clam Tagelus plebeius Lightfoot, 1786 were investigated on an intertidal sandflat on the southeast coast of Brazil (Enseada Beach, São Sebastião, state of São Paulo) between April 1997 and April 1998. Two rectangular sites of 50 X 10 m parallel to the waterline were established, site A (upper intertidal level) and site B (middle intertidal level), where the samples were taken in an 0.5 x 0.5 m quadrat. High abundances were recorded in winter and spring, with no significant differences between the sites. The high bivalve abundances were related to the presence of very fine homogeneous sediment with low salinities. Tagelus plebeius had negative allometric growth, characteristic of deep burrowers for the relationships DM/SL and AFDM/SL. Parameters of the modified von Bertalanffy growth function were: L∞ = 67.01 mm, K = 1.73 year-1, t0 = -0.11 year, C = 0.43, WP = 0.96. The instantaneous mortality (Z) was 3.12 year-1, relatively high in comparison to other tropical bivalve populations. Secondary production was 1.53 g AFDM m-2 year-1, with a P/B ratio reaching 1.37 year-1. This high turnover ratio (P/B) was related to a rapid population replacement, connected with the short life span and high mortality of the species

“…Moreover, burrowing into soft substrates consists of repeated adduction and opening of the valves in the forward and backward rotational movements, integrated with protraction and retraction of the foot. This, in turn, requires a complex integration of the muscular system (TrueMan, 1966;sTanley, 1970sTanley, , 1975bPojeTa, 1987). Fordilla and Pojetaia are not very similar to most Ordovician burrowing protobranchs in shell shape and inferred musculature (Fang, 2006a).…”

“…When the valves are contracted to release anchoring and to inflate the foot, water is expelled from the mantle cavity between the valves loosening the sediment and thus decreasing the resistance to penetration. The whole process is called "burrowing sequence" and was first described by Trueman (1966).…”

The morphological evolution of bivalves is documented by a rich fossil record. It is believed that the shell shape and surface sculpture play an important role for the burrowing performance of endobenthic species. While detailed morphometric studies of bivalve shells have been done, there are almost no studies experimentally testing their dynamic properties. To investigate the functional morphology of the bivalve shell, we employed a synthetic methodology and built an experimental setup to simulate the burrowing process. Using an evolutionary algorithm and a printer that prints three dimensional (3D) objects, the first ever artificial evolution of a physical bivalve shell was performed. The result was a vertically flattened shell occupying only the top sediment layers. Insufficient control of the sediment was the major limitation of the setup and restricted the significance of the results. Nevertheless, it is demonstrated that systematic palaeontological research may substantially profit from synthetic methods. We suggest investigating functional morphologies not only by emulating the dynamical processes but also evolutionary pressure using evolutionary algorithms.
