Data from: Estimation of regional annual abundance and evidence for increasing numbers of white sharks off central California
<p>Raw data consisting of individual identification photographs of white sharks (Carcharodon carcharias) and data table with corresponding metadata. These data support PhD thesis of Paul E. Kanive entitled "VITAL RATES, ANNUAL ABUNDANCE, AND MOVEMENT OF WHITE SHARKS IN THE NORTHEASTERN PACIFIC" and peer-reviewed manuscript "Estimation of regional annual abundance and evidence for increasing numbers of white sharks off central California."</p>
Figure 2 in The dentition of the extinct megamouth shark, (Lamniformes: Megachasmidae), from southern California, USA, based on geometric morphometrics
Figure 2. Homologous landmark (numbered black or white circles) and semi-homologous landmark (red circles with asterisk [*] connected by red lines) on tooth samples of Megachasma applegatei (A), M. pelagios (B), and Odontaspis ferox (C) for principal component analysis (not to scale). Seven homologous landmarks: 1, the crown apex, 2 and 3, right- and left-most extremities of the crown; 4, apical-most point around the middle of the crown base; 5 and 6, basal extremity of each of the two root lobes; and 7, apical-most point of the basal root concavity.
Figure 3. A in The dentition of the extinct megamouth shark, (Lamniformes: Megachasmidae), from southern California, USA, based on geometric morphometrics
Figure 3. A. Scatter plot diagram showing principal component analysis of 207 teeth of Megachasma applegatei (black plots) compared with all 178 teeth of extant M. pelagios (red plots), and all 78 teeth of extant Odontaspis ferox separated into tooth types using different colors (symphysial teeth = green; anterior teeth = dark blue; intermediate teeth = purple; lateral teeth = brown). B. Scatter plot diagram exclusively of M. applegatei, showing examples of actual specimens (not to scale) represented by certain plots (illustrated teeth: LACM 9883, 150907, 155340, 155348, 155357, 155373, 155393, 155424, 155434, 155456, 155563, 155622, 155630, 155651, 155653, 155694, and 155700). C. Scatter plot diagram exclusively of M. pelagios, showing examples of actual specimens (not to scale: see Fig. 1C, D) represented by certain plots. D. Scatter plot diagram exclusively of O. ferox, showing examples of actual specimens (not to scale: see Fig. 1F) represented by certain plots. Asterisk (*): on axes in B and C = PC1 and PC2 originally labeled inversely by the software (see text for detail); by photograph of teeth in C-D = Upper teeth.
Figure 1. A in The dentition of the extinct megamouth shark, (Lamniformes: Megachasmidae), from southern California, USA, based on geometric morphometrics
Figure 1. A. Generalized consensus tree of extant lamniform families on the basis of molecular-based phylogenetic studies, highlighting Megachasmidae in bold (see Stone and Shimada 2019, fig. 6, and references therein). B. Extant megamouth shark, Megachasma pelagios (after Compagno 1984). C, D. Right upper (C) and right lower (D) teeth of extant M. pelagios (BPBM 22730, 446 cm TL, male) in (from top row to bottom row) lingual, labial, mesial, apical, and basal views, showing strong tendency towards homodonty. E. Extant smalltooth sand tiger, Odontaspis ferox (after Compagno 1984). F. Left upper and left lower dental series of extant O. ferox (BPBM 9335, 297(?) cm TL, male(?)) showing representative 'lamnoid tooth pattern' (A or a = anterior teeth; I or i = intermediate tooth; L or l = lateral tooth; S or s = symphysial tooth). Scale bars: B and E = 50 cm; C, D, F = 5 mm
Figure 4 in The dentition of the extinct megamouth shark, (Lamniformes: Megachasmidae), from southern California, USA, based on geometric morphometrics
Figure 4. Three reconstructed dentitions of Megachasma applegatei under three different assumptions (see text for detail). A. Artificial dentition based on Odontaspis ferox as a model. B. Artificial dentition depicted as intermediate between O. ferox and M. pelagios. C. Artificial dentition based on M. pelagios as a model. Scale bar = 5 mm (note: each scale bar applies to each respective dentition consisting of teeth with digitally adjusted sizes [see text]).
