FIG. 7 in Pelvic-Fan Flaring and Inflation in the Three-Tooth Puffer, Triodon macropterus (Tetraodontiformes: Triodontidae), with Additional Observations on Their Behavior in Captivity

FIG. 7. Dissection of branchiostegal rays and muscles of Triodon macropterus (NSMT P93783, 343 mm SL). The specimen was photographed using high-energy royal-blue light to differentiate autofluorescing alizarin-stained bones and scales from muscles (see Smith et al., 2018). (A) Overview to show position of branchiostegal rays. Rectangular box indicates area shown in part B. (B) Higher magnification view to show relative size of branchiostegal 1 in comparison with branchiostegals 2–6 and the position and size of the hyohyoidei abductores (numbers on photograph indicate branchiostegal rays).
