Fig. 10From: The influence of cuttlebone on the target strength of live golden cuttlefish (Sepia esculenta) at 70 and 120 kHzRelationship between the measured TS values for all 38 specimen of cuttlebone and cuttlefish at 70 (open circle) and 120 kHz (solid circle). Comparison of the mean TS (<TS c >) of cuttlefish with the mean TS (<TS b >) of cuttlebone was indicated as a solid triangle. Solid line indicates a reference line for comparisonBack to article page
