FIGURE 4. CMM-V-10108, a in A Miocene cetacean vertebra showing a partially healed longitudinal shear-compression fracture, possibly the result of domoic acid toxicity or failed predation
FIGURE 4. CMM-V-10108, a single CT-scan image in the sagittal plane of a Miocene pathological cetacean vertebra in left lateral view showing the broken lower portion of the centrum, the displaced piece of bone, and the new bone growth (periosteal reactive bone ventrally).
Figure 2 in Delphinid brain development from neonate to adulthood with comparisons to other cetaceans and artiodactyls
Figure 2. Linear relationship between neonate brain volume and gestation duration (in days). The regression includes only delphinids. Other species were plotted but not included in the regression. The species O. orca is indicated by a black arrow. There is a strong, positive correlation between neonatal delphinid brain volume and gestation duration; gestation duration scales to the 0.23 power of neonatal brain volume.

Figure 1. There is a strong, positive correlation between maternal body mass and neonatal brain mass in these four delphinid species; neonatal brain mass scales to the 0.51 power of maternal body mass.
Fig. 1 in Short communication Antecedent description and depiction of the recently described cetacean behaviour of trap/tread-water feeding inferred from a nineteenth-century sighting of a 'sea monster' in the Gulf of Suez, Egypt
Fig. 1 - Illustration of a nineteenth-century encounter with a purported sea monster observed in the Gulf of Suez (Andrews, 1879). The vertical body position and open mouth of what is obviously a baleen whale (the rightward animal in the group) closely resembles the photographs and digital reconstructions of the recently described, so-called 'new' or 'first' descriptions of the stationary hunting behaviour of trap/tread-water feeding, as shown in Iwata et al. (2017), McMillan et al. (2018), McCarthy et al. (2023a, 2023b), and Lu (2023). The illustration, drawn in concordance to the eyewitness report, is emblematic of the instance of such whales 'rapidly closing them [their mouths] to trap prey' (McCarthy et al., 2023a). Note the presence of seabirds, something common to all modern recorded instances of such feeding documented in humpback whales, an association which may be related to shoaling fish being driven to seek the apparent shelter of the whale's open mouth (McMillan et al., 2018).

Figure 2 in A sense of scale: Foraging cetaceans' use of scale-dependent multimodal sensory systems
Figure 2. Scale-of-senses schematic of the hypothetical interchange of sensory modalities used by baleen whales to locate prey at variable scales. The line for audition of signals from prey is faded to denote a lack of evidence for this sensory system in baleen whales. X-axis on log scale, with equivalent metric distance given in gray type, and associated scale below. Y-axis ranks the relative use of each sensory modality between 0 (no contribution) and 10 (highest contribution) relative to its own information capacity, not relative to other senses.

Figure 4 in Delphinid brain development from neonate to adulthood with comparisons to other cetaceans and artiodactyls
Figure 4. Encephalization quotient (EQ) and body lengths. Body lengths are used as a general indicator for maturity of these animals. Three delphinids (Orcinus orca, Tursiops truncatus, and Stenella coeruleoalba) are compared with EQ and body length against two members of Physeteroidea (Kogia breviceps and Physeter macrocephalus) and one member of Phocoenidae (Phocoenoides dalli). In each case, EQ declines as the animal grows toward a mature body length and perhaps beyond. EQ was measured directly from brain masses, except for a few of the larger O. orca for which brain mass was calculated from endocranial volume. Body mass varies considerably in mature animals. As a result, EQ in mature T. truncatus varies from around 3 to 5 and in O. orca from about 1.5 to 3. One outlier EQ value of 2 from a male T. truncatus was from an overweight animal.
Figure 3 in Delphinid brain development from neonate to adulthood with comparisons to other cetaceans and artiodactyls
Figure 3. Brain mass relative to maturity (assessed by body length) in six different species. The horizontal line in each species plot represents the length at maturity. Female killer whales (a) (O. orca) reach sexual maturity at about 460 cm body length and as young as 8 yr of age (Dahlheim and Heyning 1999), while male killer whales (b) reach sexual maturity at about 520 cm length when they are around 15 yr of age (Dahlheim and Heyning 1999). Female Common bottlenose dolphins (c) (T. truncatus) reach sexual maturity at a length of 235 cm and at an average age of 8–9 yr (Wells and Scott 1999), and males (d) reach sexual maturity at a length of about 245 cm and an approximate age of 10 yr (Wells and Scott 1999). Female striped dolphins (e) (S. coeruleoalba) reach sexual maturity at 180 cm and about 7 yr of age (Perrin et al. 1994); males (f) reach sexual maturity at about 185 cm and about 11 yr of age (Perrin et al. 1994). Female pygmy sperm whales (g) (K. breviceps) reach sexual maturity at about 266 cm body length (Caldwell and Caldwell 1989), and males (h) reach sexual maturity at about 270 cm length (Caldwell and Caldwell 1989). Female spinner dolphins (i) (S. longirostris) reach sexual maturity at a length of 165 cm and at an average age of 4–7 yr (Perrin and Gilpatrick 1994) while males of this species (j) attain sexual maturity at a length of about 160 cm and an approximate age of 7–10 yr (Perrin and Gilpatrick 1994). Lastly, female Dall's porpoises (k) (P. dalli) reach sexual maturity at 174 cm and about 5 yr of age (Houck and Jefferson 1999), and males (l) reach sexual maturity at about 175 cm and about 5 yr of age (Houck and Jefferson 1999).
Table 3 in Delphinid brain development from neonate to adulthood with comparisons to other cetaceans and artiodactyls
<p><i>Table 3.</i> Gestation and brain size. The predicted gestation period was derived by applying the Sacher and Staffeldt formula and using our brain mass data. Sheep (<i>O. aries</i>), cows (<i>B. taurus</i>), giraffes (<i>G. camelopardalis</i>), and hippopotamuses (<i>H. amphibius</i>) were included in the table to compare cetaceans to other members of the Cetartiodactyla taxonomic order. Humans (<i>H. sapiens</i>) were also included for comparison. Cetaceans appear to have similar neonatal/adult brain mass ratios compared to other animals of the Cetartiodactlya order. Sources for the published gestation durations and cetacean brain masses can be found in Table S1.</p><table><thead><tr><th></th><th></th><th></th><th></th><th>Published</th><th>Predicted</th></tr></thead><tbody><tr><th>Taxonomic family</th><td>Neonatal</td><td>Adult brain</td><td>Neonate/</td><td>gestation</td><td>gestation</td></tr><tr><th>Genus species</th><td>brain mass (g)</td><td>mass (g)</td><td>adult (%)</td><td>(days)</td><td>(days)</td></tr><tr><th colspan="6">Delphinidae</th></tr><tr><th><i>C. commersonii</i></th><td>370</td><td>783</td><td>47.3</td><td>334</td><td>324</td></tr><tr><th><i>D. delphis</i></th><td>430</td><td>715</td><td>60.2</td><td>363</td><td>359</td></tr><tr><th><i>G. griseus</i></th><td>796</td><td>2,132</td><td>37.3</td><td>410</td><td>386</td></tr><tr><th><i>L. acutus</i></th><td>733</td><td>1,285</td><td>57</td><td>365</td><td>401</td></tr><tr><th><i>L. obliquidens</i></th><td>523</td><td>1,198</td><td>43.6</td><td>356</td><td>352</td></tr><tr><th><i>O. orca S. attenuata S. longirostris</i></th><td>3,006 353 247</td><td>6,642 711 541</td><td>45.3 49.6 45.6</td><td>553 — —</td><td>566 304a 286a</td></tr><tr><th><i>S. bredanensis</i></th><td>706</td><td>1,454</td><td>48.6</td><td>378</td><td>388</td></tr><tr><th><i>T. truncatus</i></th><td>685</td><td>1,550</td><td>44.2</td><td>376</td><td>377</td></tr><tr><th colspan="6">Monodontidae</th></tr><tr><th><i>D. leucas</i></th><td>938</td><td>2,087</td><td>44.9</td><td>456</td><td>414</td></tr><tr><th colspan="6">Phocoenidae</th></tr><tr><th><i>P. phocoena</i></th><td>242</td><td>506</td><td>47.7</td><td>316</td><td>266</td></tr><tr><th><i>P. dalli</i></th><td>270</td><td>803</td><td>33.6</td><td>334</td><td>282</td></tr><tr><th colspan="6">Physeteridae</th></tr><tr><th><i>P. macrocephalus</i></th><td>3,308</td><td>7,693</td><td>43</td><td>547</td><td>582</td></tr><tr><th colspan="6">Pontoporiidae</th></tr><tr><th><i>P. blainvillei</i></th><td>154.9</td><td>223.9</td><td>69.2</td><td>319</td><td>271</td></tr><tr><th colspan="6">Ziphiidae</th></tr><tr><th><i>M. europaeus</i></th><td>971</td><td>1,680</td><td>57.8</td><td>—</td><td>—</td></tr><tr><th colspan="6">Balaenopteridae</th></tr><tr><th><i>B. physalus</i></th><td>2,640</td><td>6,718</td><td>39.3</td><td>342</td><td>537</td></tr><tr><th>Bovidae <i>B. taurus O. aries</i></th><td>199b 69</td><td>456b 130d</td><td>43.6 53</td><td>278c 150e</td><td>270 208</td></tr><tr><th>Giraffidae <i>G. camelopardalis</i></th><td>428f</td><td>537f</td><td>79.7</td><td>459c</td><td>363</td></tr><tr><th>Hippopotamidae <i>H. amphibius</i></th><td>195b</td><td>590b</td><td>33.1</td><td>240e</td><td>258</td></tr><tr><th>Hominidae <i>H. sapiens</i></th><td>380g</td><td>1,400b</td><td>27</td><td>280e</td><td>324</td></tr></tbody></table><p><sup>a</sup> Perrin <i>et al.</i> (1977).</p><p><sup>b</sup> Sacher and Staffeldt (1974).</p><p><sup>c</sup> Kiltie (1982).</p><p><sup>d</sup> Minervini <i>et al.</i> (2016).</p><p><sup>e</sup> Hayssen <i>et al.</i> (1993).</p><p><sup>f</sup> <i>Gra¨ıc et al.</i> (2017).</p><p><sup>g</sup> Blinkov and Glezer (1968).</p>
