Fig. 3. Relative densities for Irrawaddy dolphins (a) and finless porpoises (b). Densities are represented as the number of sightings per km searched in 2 × 2 km grid cells. This includes all on-effort sightings and all effort tracks from the start of the project in Jun.2008 through Oct. 2011.

Fig. 4. PMCT and necropsy images of lesions caused by the nematode Crassicauda fuelleborni or Crassicauda sp. in the male reproductive organs of Indo-Pacific finless porpoises Neophocaena phocaenoides stranded in Hong Kong waters. (A) Case 11, subadult male, heterogeneous lesion (arrowhead) with both isoattenuated and hyperattenuated content associated with the prostate (asterisk), nematode found was later identified as C. fuelleborni. (B) Case 13, adult male, homogenous hyperattenuated probable Crassicauda-related lesion in the tissues surrounding the penis (asterisk). (C) Case 6, juvenile male, isoattenuated lesion with some hypoattenuated and hyperattenuated foci associated with the right testis (arrowhead). (D) Case 6, juvenile male, the corresponding abscessed lesion at the right epididymis with nematodes later identified as Crassicauda sp.

Fig. 2. PMCT and necropsy images of lesions caused by the nematode Crassicauda sp. in an Indo-Pacific finless porpoise Neophocaena phocaenoides stranded in Hong Kong waters. (A) Case 1, subadult female, homogeneous isoattenuated lesion (arrowhead) in the ventral abdominal muscle (upper) and the corresponding nodule containing coiled and fragmented nematodes later identified as Crassicauda sp. (lower). (B) Case 1, subadult female, heterogeneous lesion (arrowhead) with isoattenuated content and hypoattenuated foci interpreted as small gas collections in the ventral abdominal muscle (upper) and the intact and coiled nematodes collected from the corresponding nodule and later identified as Crassicauda sp. (lower).

(A) Case 8, adult female, heterogeneous lesion (arrowhead) with a hyperattenuated rim and isoattenuated content in the ventral abdominal muscle (upper) and the corresponding nodule containing decomposed worms among caseous debris (lower). (B) Case 8, adult female, heterogeneous lesion (arrowhead) with both hyperattenuated and isoattenuated content in the ventral abdominal muscle (upper) and the corresponding nodule containing creamy pink caseous debris (lower). (C) Case 1, subadult female, homogeneous hyperattenuated lesion (arrowhead) in the ventral abdominal muscle (upper) and the corresponding nodule containing dried and pale yellow caseous debris (lower).

Fig. 1. PMCT images showing the anatomy of the mammary glands and adjacent structures, as well as an example of Crassicauda-related mammary gland pathology in Indo-Pacific finless porpoises Neophocaena phocaenoides. (A) Recently pregnant adult female, axial cross-section of the mammary glands (MG) and adjacent structures (H: m. hypaxialis lumborum, AC: abdominal cavity, RA: m. rectus abdominis, MA: mm. abdominales, SM: superficial muscles between the mammary glands and blubber). (B) Recently pregnant adult female, longitudinal cross-section of the mammary glands, with branch-like ducts converging into the central lactiferous ducts (CLD). (C) Sexually mature adult female with severe parasitic infection of the mammary glands and adjacent muscles, notably with multiple hyperattenuated lesions in the muscles dorsal to the mammary glands with one invading and compressing the mammary gland tissues on the right side.

Figure 2 shows a longitudinal slice of a tooth consisting of translucent and opaque zones under the transmitted light. The tooth is clearly divided into two parts by a highlighted neonatal line. The part inside of the neonatal line is dentine, and the outside is cementum. Ages were counted by GLGs in dentine, and basic data are shown in table 1. The oldest individual was 13 years old, while the youngest ones died about a month after birth.
