The microstructure of the statoliths of ommastrephids has been used widely for estimating squid age since the late 1970s (Lipinski 1978, Arkhipkin 2005), in addition to the duration of the paralarval phase and mating events (Dawe & Beck 1997).
In the current work we sought (1) to detect any qualitative associations between statolith microstructure (specifically increment appearance) and the distribution of calcium and strontium within squid statoliths, and (2) to assess whether any patterns discovered were consistent between sexes, stages of development, and ambient temperatures.
As statoliths calcify continuously throughout the life of the animal (like their shells), they can contain ontogenetic growth histories in the form of growth rings, as the rates of growth change throughout the life of the animal.
Statocysts transparent and statoliths clearly visible through posterior region of head.
A total of 340 statoliths from the three sites were satisfactorily prepared for age determination.
(basking shark) gill rakers, and hundreds of squid statoliths. The teleost assemblage at this site includes pleuronectids and bothids (right- and left-eyed flatfishes), serranids (basses), atherinids (silversides), mugilids (mullets), gobiids (gobies), clupeids (herrings), and other nearshore forms (Clarke and Fitch 1979), but the vast majority of the otoliths are of sciaenids.
At 4[degrees]c, starch-containing statoliths sedimented normally in wildtype but auxin transport was abolished indicating that the mutants are affected in an aspect of signal transduction that occurs after statolith sedimentation but prior to auxin transport.
Statoliths are solid calcareous concretions located in the statocysts (equilibrium organs) of coleoid cephalopods including squid, cuttlefish, sepiolids, and octopods (Clarke 1966) (Fig.
Potential of statoliths for interpreting-coleoid evolution: a brief review.
Hard structures often are used for aging squid and most studies measure statoliths (Spratt, 1978; Lipinski, 1986; Jackson et al., 1993; Durholtz et al., 2002).

Squid use calcium carbonate crystals to make balance organs, called statoliths, that provide the ability to orient themselves when swimming.
