Fig. 2 in Abundance And Summer Distribution Of A Local Stock Of Black Sea Bottlenose Dolphins, Tursiops Truncatus (Cetacea, Delphinidae), In Coastal Waters Near Sudak (Ukraine, Crimea)

Fig. 2. Sightings of bottlenose dolphins near Sudak in 2011–2012. Sightings are indicated by circles of different size, depending on the group size category; sightings during the line transect survey (LTS) on August 4, 2012, are marked as filled circles, and other sightings (non LTS) are marked as empty circles. The LTS transects are shown as a zigzag line, and the LTS area is bordered by a contour line.

Figure 10 in Vertebral osteology in Delphinidae (Cetacea)

Figure 10. Isolated vertebrae from fossil cetaceans for which functional and/or evolutionary context may be predicted. A, 11 caudal vertebrae of 'Odontocete indet.' CMM-V-1694 in dorsal view, with an inferred gap in vertebral sequence. Note that the terminal (fluke) vertebrae are elongate. B, two mid torso vertebrae of Hadrodelphis calvertense CMM-V-11 in left lateral view. Metapophyses are present, neural processes are short and vertebrae are spool-shaped. C, six anterior and mid torso vertebrae of Albireo whistleri UCR 14589 in left lateral view. Metapophyses are present and low, but neural spines are very tall and centra are discoidal. D, three chest and five torso vertebrae of USNM 15727 'Tursiops sp.' in left lateral view. Note the lack of metapophyses on anterior torso vertebrae. All scale bars = 5 cm.

Figure 8 in Vertebral osteology in Delphinidae (Cetacea)

Figure 8. Two representations of the allocation of vertebrae to series in delphinid cetaceans. A, comparison of column subdivisions in terrestrial mammals, in cetaceans using terrestrial nomenclature and in cetaceans using cetacean nomenclature. Subdivision of the torso is applicable only to delphinids with syncliny. S = synclinal point. B, regional morphology of Lagenorhynchus acutus (MCZ 61008) by classic and cetacean column series in dorsal (above) and lateral (below) views. N = neck, TS = tail stock, F = fluke.

Figure 7 in Vertebral osteology in Delphinidae (Cetacea)

Figure 7. Neural spine inclination (NSI) at different locations along the column in four delphinid species: Orcinus orca, AMNH 34276, total count = 53; Sotalia fluviatilis (MCZ 7097, vertebral count = 54); Tursiops truncatus (MCZ 7899, vertebral count = 62+); Lagenorhynchus acutus (MCZ 60939; vertebral count = 82). Note that the position of the synclinal point (arrows) is more posterior in species with higher counts, and that Orcinus does not exhibit syncliny.

Figure 6 in Vertebral osteology in Delphinidae (Cetacea)

Figure 6. Vertebral count and shape in delphinids. A, relationship between total counts and series counts. B, relationship between total count and lumbar CL/CH. C, CL/CH traces for four species, each with syncliny and a secondary rise in CL (arrows). Note the progressive reduction in CL/CH with increasing total count.

Figure 4. Vertebral dimensions in Orcinus orca (AMNH 34276) and Lagenorhynchus acutus (MCZ 60939), with classic divisions of the column. Cervical and anterior thoracic vertebrae of the Orcinus column are mounted, making CH and CW measurements impossible. Cv = cervical.
