Fig. 6From: The influence of cuttlebone on the target strength of live golden cuttlefish (Sepia esculenta) at 70 and 120 kHzComparison of the echograms showing the dependence of echo amplitude on the dorsal orientation of cuttlebone at 70 (a) and 120 kHz (b). The echogram was recorded as a function of the tilt angle of cuttlebone with significant responses at spine (posterior, −90°), dorsal (0°) and head (anterior, +90°) orientationsBack to article page
