FIG. 4. Frames from a video of Triodon macropterus, Fish 3 (320 mm SL), recorded during the night (1900–0400 hours) of 16 to 17 November 2020 at the Okinawa Churaumi Aquarium. Frames A–U show behaviors that occurred during a 1:11 minute interval that included 13 buccal cavity expansions and 11 pump-like expansions and retractions of the pelvic fan. We term this behavior pump flaring. No inflation occurred. Supplemental Video 2 (see Data Accessibility) was the basis for this figure.

FIG. 3 in Pelvic-Fan Flaring and Inflation in the Three-Tooth Puffer, Triodon macropterus (Tetraodontiformes: Triodontidae), with Additional Observations on Their Behavior in Captivity

FIG. 3. Kinematics of pelvic-fan flaring and inflation in two individuals of Triodon macropterus at the Okinawa Churaumi Aquarium during six handling trials. Shaded gray boxes behind the bars indicate when the fish was held in hand; at other times during the trials the fish was free swimming. Brackets show periods of ultrasound examination. Numbers and letters in circles for parts D and F link figure numbers to the kinematic analysis. (A, B) Trials 1 and 2 of Fish 1 (308 mm SL). Fish 1 flared its pelvic fan in response to being handled but did not inflate in either trial. Fish 1 had been handled during routine care during 16 months in the aquarium. (C–F) Trials 1–4 of Fish 2 (376 mm SL). Fish 2 flared its pelvic fan and inflated in all four trials in response to handling; it had been handled at the aquarium but was a relatively new resident (3 months) at the time of the trials.
