Nautilus Movement and Distribution in Palau, Western Caroline Islands

Abstract: Long-term movement of up to 150 kilometers in 332 days by tagged, living Nautilus, and postmortem shell drift of 1000 kilometers in 138 days, corroborate and explain the cosmopolitan distribution of many fossil shelled cephalopods.

“…The studies of Hamada (1964Hamada ( , 1984 and Toriyama et al (1964) on the necroplanktic features of recent Nautilus shells provide evidence for postmortem driftings of 3000 km and floats of more than 1 year, which are reflected in bioerosion and epifaunal settlement. Similarly, Saunders and Spinosa (1979) recorded a postmortem drift of a Nautilus shell over a distance of 1000 km (between Palau and Mindanao) in a maximum of 138 days, an average of approximately 7 km per day. The maximum drifting distance (so far) involved a Nautilus specimen that drifted ashore after 11 years (Ishii 1981).…”

“…La concha del género Aturia se caracteriza por tener el sifúnculo en posición dorsal y cuellos septales muy largos (Ward, 1980;Dzik, 1984) lo que permite una eficiente capacidad de desacople del líquido de las cámaras (Ward, 1980) y por ello tiene el mayor potencial de flotabilidad y de deriva post morten en comparación con la concha de los nautiloideos (Chirat, 2000); en el caso del género Nautilus la flotabilidad post morten puede ser positiva o negativa (Mapes et al, 2010), si es positiva, se sabe que la concha de Nautilus puede derivar por días o meses (House, 1987), distancias de varias decenas, cientos e incluso superar los 1000 kilómetros fuera del área en que habitan antes de depositarse (Saunders y Spinosa, 1979). Ello, en principio, explicaría la amplia distribución paleogeográfica de la especie Aturia cubaensis (Lea, 1841); de hecho, Chirat (2000) cree que América Central y las regiones adyacentes, fue la región donde Aturia cubaensis (Lea, 1841) habitó y que las conchas derivaron fácilmente desde esta zona, atravesando el Atlántico hasta el Mediterráneo y el Pacífico hasta Japón y Pacífico Sur, alcanzado el sur de América del Sur.…”

“…Close similarities in biology and ecology of other Nautilus species (Saunders, 1981b;Saunders and Landman, 2010;Sinclair et al, 2007;Strugnell et al, 2006;Ward and Saunders, 1997;Wray et al, 1995) argues for the inclusion of all members of this group in any management decisions. All current evidence suggests the life history of slow growth, long life, low fecundity and restricted dispersal and recruitment are features of all Nautilus and Allonautilus species (Saunders, 1981a;Saunders et al, 1989;Saunders and Spinosa, 1979;Saunders and Ward, 1987;Sinclair et al, 2007;Tanabe et al, 1990;Ward, 2008;Ward and Saunders, 1997). The shells of N. pompilius, N. macromphalus and A. scrobiculatus are all marketed and sold by the international shell trade.…”
