| Abstract |
This review provides a critical synthesis and analysis of the extensive body of knowledge of predation by the Naticidae, a cosmopolitan family of burrowing marine gastropods. First, the diversity of shell boring predation is reviewed and documented for ten taxa (nine marine, one terrestrial), in order to facilitate comparative analyses. These predators are: Naticidae, Muricidae, Cassidae and Capulidae (Gastropoda, Prosobranchia); Okadaia (Gastropoda, Opisthobranchia); Aegopinella (Gastropoda, Pulmonata); Octopus (Cephalopoda); Pseudostylochus (Turbellaria); Nematoda; and Asemichthys (Pisces). Second, the proximate mechanisms of naticid predation are explicated. Third, the known prey of naticids are tabulated; over 80 families of gastropods and bivalves are subject to naticid predation which is essentially restricted to soft-substrate prey taxa. Fourth, the fossil record of naticid predation is summarized; this predation dates from the Cretaceous, with a possible boring "experiment" in the early Triassic. The diagnostic countersunk naticid boreholes are recognizable in fossil and recent faunas; naticid predation is a readily documented aspect of the otherwise elusive soft-bottom food web. Fifth, the studies on physiology and ecology of naticid predation are integrated into a conceptual framework. These aspects of naticid predation (energy budgets, prey size and species choice, unsuccessful predation) indicate a successful albeit rather stereotyped mode of predation. The macroevolutionary implications (escalation, or "arms races") suggest generalized predator-prey coevolution. |
