“…Since direct evidence comparable to Baumiller's (1990) report of a platyceratid gastropod in contact with a drilled invertebrate is not available, we must rely on other criteria. Drill hole plan and cross sectional shape, size, placement and number of drills per shell, as well as the presence of a capable predator within an assemblage of drilled prey are common -and also compelling -evidence used in identifying the drilling agent (Carriker and Yochelson 1968;Bromley 1981;Harper and Wharton 2000;Baumiller and Bitner 2004;Kowalewski 2004;Harper 2005;Baumiller et al 2006). In our case, the small size, cylindrical morphology and lack of qualitatively significant valve or site selectivity of drill holes are characteristic of muricid drillings (Carriker and Van Zandt 1972;Kowalewski 2004).…”

“…Conventionally, brachiopods were assumed to be largely immune from predation as a consequence of low nutritional value, unpalatability, spicules and/or toxins (Thayer 1985;Harper and Wharton 2000). But the 'low nutritional value' argument for example, does not find strong support in quantitative energetic analyses (Peck 1993); in fact, cost-benefit analyses suggest that they may be profitable prey to drilling gastropods (Tuura et al 2007).…”

“…Kowalewski et al (2005) report a slight but relatively continuous increase in drilling frequencies from the Ordovician (, 0.5%) to the Permian (2%). Although few drillings of brachiopods have been reported from the Mesozoic, occasionally high frequencies also occur (see Harper and Wharton 2000;Harper 2003).…”

Drill holes in Australian Cainozoic brachiopods

The fossil record of drill holes in marine invertebrates has received a considerable amount of interest from paleontologists, primarily due to its importance for reconstructing the history of interactions between drilling predators and their prey. Such drill holes have been described in numerous studies of Paleozoic brachiopods but rarely in those focusing on brachiopods of the post-Paleozoic, a striking pattern given that in the late Mesozoic and Cainozoic drilling gastropods diversified and frequencies of drilled molluscs increased dramatically. During the past several years, however, drilled brachiopods were reported in several studies of the Mesozoic and Cainozoic, suggesting that this phenomenon may be more common than has been previously assumed. Here we report on 10 genera of brachiopods from four Cainozoic basins in Australia of which 7 shows evidence of having been drilled by predators. Of 298 specimens examined, 38 contain a single complete hole. Drilled specimens were identified in all 4 basins and in all stratigraphic units. When considered in the context of recent reports of drilled Cainozoic brachiopods, these Australian brachiopods further imply that drilling predation on these invertebrates was geographically, taxonomically and temporally widespread.

“…Papers concerning the temporal trend in bioerosion drilling frequency on articulated brachiopods shows an increase from the Cretaceous onward (Harper and Wharton, 2000) which is tied to the activity of muricid and naticid gastropods (Bromley, 2004). Indeed, predation frequency on both fossil and living brachiopods has been reported as rare, with the exception of studies by Baumiller and Bitner (2004) and Hoffmeister et al (2003).…”

Bioerosion on Brachiopod Shells of a Thanatocoenosis of Alboràn Sea (Spain)

Bioerosion on shells of a brachiopod-bearing thanatocoenosis dredged on red-coral sea-bottom (depth 100 m, 12 miles off the southwestern coast of Alborán Island, Spain) was analyzed. Although low, the intensity of predation was noticeable. Predation drill holes belonging to the ichnogenera Oichnus simplex, O. paraboloides and O. ovalis were recognized. They were probably produced by Muricidae and Marginellidae (gastropods) and octopod cephalopods, respectively. Oichnus ovalis was more common on Terebratulina retusa. A strong selectivity with respect to species, valve, and size was noted. Terebratulina retusa, especially small individuals, was preyed upon more often than any other species. The central portion of both valves was attacked more frequently than expected by chance.

“…The restriction of brachiopods to safe places or refuges in modern hardbottom habitats is generally ascribed either to high carnivorous predation pressure (Harper & Wharton 2000, Aberhan et al 2006, Gili et al 2006, or to high competition pressure, owing to the evolution of mollusks and other groups with superior abilities to compete for space and food (Thayer 1985, Bush et al 2007, NovackGottshall 2007. The survivorship of brachiopods in present-day habitats thus may depend on abundance of prey and competitive refuges, which generally correlates with substrate complexity (Hixon & Menge 1991), and on efficiency in resource utilization and resistance to consumer pressure (Peck 1996, Peck et al 2005.…”

Substrate exploitation and resistance to biotic disturbance in the brachiopod Terebratalia transversa and the bivalve Pododesmus macrochisma

To test the hypothesis that epifaunal bivalves are more resistant to biotic disturbance than brachiopods, I evaluated abundances and body size of the brachiopod Terebratalia transversa and the anomiid bivalve Pododesmus macrochisma, which co-occur in the San Juan Islands (Washington State, USA, eastern Pacific). The proportion of bare space correlated with intensity of biotic disturbance had negative effects and surface rugosity had positive effects on abundance of T. transversa. Both rugophilic settlement and post-settlement mortality of juveniles due to biotic disturbance restrict T. transversa to crevices and complex substrates formed by solitary ascidians and giant barnacles. Its juveniles are under-represented on flat substrates, implying lower survivorship than in crevices, where juveniles are common. Abundance of the byssally-cemented bivalve P. macrochisma is negatively affected by rugosity and does not decrease with increasing bare space. P. macrochisma size patterns do not differ between crevices and flat substrates. Flat valves and high post-settlement mobility probably increase its juvenile survivorship under grazing pressure. T. transversa is not able to re-attach after settlement and is thus less resistant to grazing effects than P. macrochisma. This study supports the hypothesis that brachiopods are more negatively affected by biotic disturbance than epibyssate bivalves. Although brachiopods can be less preyed upon by carnivorous predators than epibyssate bivalves, T. transversa is affected more negatively by grazing than P. macrochisma. The evolutionary decline of brachiopod abundance in shallow habitats may represent responses to a heavy pressure on juveniles by grazers that evolved during the Mesozoic.KEY WORDS: Bivalve mollusk · Brachiopod · Disturbance · Grazing impact · Substratum · Subtidal marine macrobenthos Resale or republication not permitted without written consent of the publisher
