FIG. 10 in Pelvic-Fan Flaring and Inflation in the Three-Tooth Puffer, Triodon macropterus (Tetraodontiformes: Triodontidae), with Additional Observations on Their Behavior in Captivity
FIG. 10. Photographs of digestive tract removed from Triodon macropterus, NMST P93783, 343 mm SL, anterior to left. (A) Digestive tract from esophagus to pseudocloaca showing the rectangular-shaped stomach with the bile duct entering the body of the stomach. The thin-walled pyloric region of the stomach is where most of the inflation occurs. (B) Lining of anterior region of digestive tract. (C) Lining of posterior half of the digestive tract.
FIG. 9 in Pelvic-Fan Flaring and Inflation in the Three-Tooth Puffer, Triodon macropterus (Tetraodontiformes: Triodontidae), with Additional Observations on Their Behavior in Captivity
FIG. 9. Dissection of Triodon macropterus, NSMT P0110597, 360 mm SL. Black dashed lines indicate cut edges. (A) Skin of the pelvic fan and abdomen removed to show muscles of the pelvic fan. (B) Dissection to show the viscera and extent of the ventral abdominal recess (white dashed line). Postcleithral bones removed to view abdominal cavity. The abdominal cavity has small ventral peritoneal folds. The stomach in this specimen everted into the buccal cavity because of barotrauma. It tore away from its connection with the intestine at the pyloric region; the rest of the intestinal tract, including Tyler's pouch, is in place as in life.
FIG. 6 in Pelvic-Fan Flaring and Inflation in the Three-Tooth Puffer, Triodon macropterus (Tetraodontiformes: Triodontidae), with Additional Observations on Their Behavior in Captivity
FIG. 6. Ultrasound recording of Triodon macropterus, Fish 2 (376 mm SL), at the Okinawa Churaumi Aquarium. The kinematic record of this trial is shown in Figure 3D. The circumference of the stomach is outlined with a yellow line. Black areas within the stomach are water; white spots are air bubbles. (A) Ultrasound image showing the circumference (13.0 cm) of the stomach and the area of one slice of the stomach (10.8 cm2) 30 seconds into the trial. (B) Ultrasound image showing increase in the circumference (15.5 cm) and the slice area of the stomach (17.3 cm2) 2:30 minutes after the image shown in Figure 6A.
FIG. 2 in Pelvic-Fan Flaring and Inflation in the Three-Tooth Puffer, Triodon macropterus (Tetraodontiformes: Triodontidae), with Additional Observations on Their Behavior in Captivity
FIG. 2. Photographs of Triodon macropterus showing pelvic-fan flaring and inflation. (A) Individual (collected 8 February 2007), 300 mm TL, in display tank at the Okinawa Churaumi Aquarium showing pelvic fan fully retracted and no inflation. Photograph by Atsushi Kaneko; modified from Matsuura et al. (2017). Photograph reprinted with permission from the Ichthyological Society of Japan. (B) Specimen with pelvic fan flared, abdomen uninflated, LBRC-F 00805, 324.5 mm SL, sex unknown. Caught by hook and line in the Maluku Sea, Indonesia, and purchased at a fish market, 11 July 2009. Photograph by Teguh Peristiwady; modified from Wibowo et al. (2020: fig. 2a). Photograph reprinted with permission from the Jurnal Iktiologi Indonesia (see Supplemental Figure 1D, Supplemental Table 1; see Data Accessibility). (C) Individual photographed shortly after capture with pelvic fan flared and abdomen inflated. The fish was destructively sampled for parasites (see Beveridge et al., 2014; Bray and Justine, 2014), 361 mm FL, female. Caught by hook and line off Récif Toombo, Nouméa, New Caledonia (22834.5650S, 166827.6360E), 2 July 2009. Collected and photographed by Jean-Lou Justine (see Supplemental Fig. 1H, Supplemental Table 1; see Data Accessibility).
FIG. 5. Frames from a in Pelvic-Fan Flaring and Inflation in the Three-Tooth Puffer, Triodon macropterus (Tetraodontiformes: Triodontidae), with Additional Observations on Their Behavior in Captivity
FIG. 5. Frames from a video of Triodon macropterus, Fish 2 (376 mm SL), inflating underwater during handling for Trial 4 at the Okinawa Churaumi Aquarium. The kinematic record of this trial is shown in Figure 3F. During this 2:59 minute sequence, the fish buccal pumped water into the stomach for inflation. As the abdomen expanded, the position of the ocellus changed (white arrows; changes in the position of the ocellus are primarily the result of inflation and not further pelvicfan flaring). (A) At 27 seconds into the trial, Fish 2 showed no external signs of inflation. (B) At 49 seconds, external signs of inflation became visible. (C) At 01:19 minutes into being held, the fish was moderately inflated because water had been buccal pumped for inflation into the
FIG. 1 in Pelvic-Fan Flaring and Inflation in the Three-Tooth Puffer, Triodon macropterus (Tetraodontiformes: Triodontidae), with Additional Observations on Their Behavior in Captivity
FIG. 1. Illustration from Breder and Clark (1947: fig. 3) showing their terminology for the viscera of Triodon macropterus (SU 13747, 391 mm SL). Gray shading indicates their interpretation of the extent of the abdominal cavity into the pelvic fan. In this paper, we revise their interpretations of anatomical structures and show that, contrary to their interpretation, T. macropterus can inflate.
FIG. 8. X in Pelvic-Fan Flaring and Inflation in the Three-Tooth Puffer, Triodon macropterus (Tetraodontiformes: Triodontidae), with Additional Observations on Their Behavior in Captivity
FIG. 8. X-rays of two specimens of Triodon macropterus showing differences in pelvic bone position related to extent of pelvic-fan flaring. The anterior tip of the long cleithrum extends to the lower-jaw joint. White stars indicate center of rotation of the pelvic bone at its connection with the cleithrum. (A) USNM 451516, 358 mm SL. Fan partially flared to ~258. Long ribs are numbered 2–7. (B) NSMT P0110597, 360 mm SL. Fan partially flared to ~458. White arrows indicate lines of actions of the muscles that flare and retract the pelvic fan. Patches of skin and scales were removed from this specimen for another study (see Matsuura et al., 2017).

Figure 1 in Observations of a greater sac-winged bat pup (Saccopteryx bilineata) with a chromatic disorder
Figure 1: Saccopteryx bilineata pup in its day-roost with normal pigmentation (A). The wavy white lines are only faint and not yet pronounced like in adult bats. Photo credit: S. Ripperger. Mother-pup pair in a day roost (B). The mother is clearly distinguishable from the pup by her brown fur and the pronounced white lines on the back. Since this pup is older the faint white lines are also starting to appear on its back. Photo credit: M. Stifter.
Figure 3 in Observations of a greater sac-winged bat pup (Saccopteryx bilineata) with a chromatic disorder
Figure 3: The female pup of Saccopteryx bilineata with chromatic disorder (A). Both wing membranes, the tail membrane, and the skin showed normal colouration (B) whereas the fur was entirely white. However, some of the white hairs had black tips (C). Photo credit: S. Ripperger.
Figure 2 in Observations of a greater sac-winged bat pup (Saccopteryx bilineata) with a chromatic disorder
Figure 2: Entire isolation call from the leucistic pup. The multisyllabic call is composed of three different syllable types: (vs) variable simple syllables, end syllables which include the composite syllable type (cs) and the short stereotyped syllable type (ss). The composite syllable type is composed of two parts, a noisy part which is facultative (nc), connected to a tonal part (tc). The spectrogram depicts frequency (kHz) as a function of time and was generated using a 1042 point-fast Fourier transform with a Hamming window with 50 % overlap. Above the spectrogram, the oscillogram is depicted, displaying time on the x-axis and amplitude on the y-axis. Nomenclature follows (Fernandez and KnÖrnschild 2017).
