Quantitative elemental imaging of octopus stylets using PIXE and the nuclear microprobe
By utilising targeted microprobe technology, the analysis of elements incorporated within the hard bio-mineralised structures of marine organisms has provided unique insights into the population biology of many species. As hard structures grow, elements from surrounding waters are incorporated effectively providing a natural ‘tag’ that is often unique to the animal’s particular location or habitat. The spatial distribution of elements within octopus stylets was investigated, using the nuclear microprobe, to assess their potential for determining dispersal and population structure in octopus populations. This was investigated in adult Octopus pallidus sourced from a commercial fishery in Tasmania.

- Statement
- General composition analyses were performed on stylets collected from adult O. pallidus sourced from the commercial fishery in Tasmania in October 2005. Powder x-ray diffraction was conducted to determine mineral composition (Mineral Resources Tasmania, Australia). To determine total inorganic content 'loss-on-ignition' (combustion of organic material) was also conducted. Secondly, infrared spectroscopic analysis was conducted on the stylet with most of the outer sheath removed (Central Science Laboratory, University of Tasmania). For further details consult the published paper. Nuclear microprobe analysis Five stylets were sourced from adult O. pallidus also collected from the commercial fishery. Two 'juvenile' stylets were also sourced from five month old aquaria-reared O. pallidus in January 2006. For further details consult the published paper.
