“…Failure of the armor could result in internal soft tissue and organ damage leading to death, infection, as well as subsequent predatory and territorial fighting vulnerability (Reimchen, 1988;Mapes et al, 1989;Mcclanahan and Muthiga, 1989;Kodera, 1994;Zuschin et al, 2003). Failure of a tooth can lead to reduced feeding rates and territorial fighting vulnerability (Magalhaes, 1948;Kent, 1983;Geller, 1990). A fundamental understanding of threat-protection design principles and mechanisms underlying predator-prey interactions has great potential to yield insights into evolutionary pathways (Vermeij, 1987;Dietl and Kelley, 2002).…”

“…A large buccinid whelk, Pleuroploca australasia Perry, occurs in the subtidal study sites but has not been observed feeding on Pinna bicolor, although related species prey on Pinnidae elsewhere (Paine 1963;Kent 1983). It is likely that most of the rest were killed by starfish, especially Coscinasterias calamaria Gray.…”

Random samples of P. bicolor were taken from one intertidal and two subtidal sites over 3 years and tagged individuals of P. bicolor were followed for up to 6 years at two other sites. P. bicolor is dioecious. Mature gonads were observed in early summer (November-January) with a peak in December each year. The pattern appeared to differ little between years or sites but the period of maximum gonad activity was shorter at the intertidal site. Growth was slower at the intertidal site and animals reached a smaller maximum size there than at the subtidal sites, which differed slightly. It is concluded that P. bicolor can reach reproductive size (15 cm shell length) in little more than a year but, at least subtidally, have a low mortality rate (less than 0.1 year-') thereafter. Recruitment is variable and it is argued that at some sites superficially 'stable' densities of P. bicolor are maintained by occasional strong recruitments, which are 'stored' in the population because of low adult mortality. The implications of this for management and for the use of P. bicolor as a biological monitor are discussed.

“…Weldon (1981) found that the snails Busycon contrarium and B. spiratum bite the feet of the molluscivorous snails Fasciolaria tulipa and Pleuroploca gigantea, presumably to repel these predators. Kent (1983) reported that both species also use radular rasping in intra-and interspecific competitive interactions. We commonly saw A. columbiana repel conspecifics that were attempting to mount their shells.…”
