Additional information/photographs accompanying form NHM136

Brief
examination of the carcass:
Date: 20/01/2006
Recovered: SX487507
Species: Common dolphin (Delphinus
delphis)
Sex: Male
Length: 2.23 m
Condition:
Damage to fins (wear and decomposition) bone from tip of
beak and lower jaw exposed. Small amount of blood was observed leaking from the
blowhole. Two puncture marks of approximately 15 mm each were found on the
carcass. Figure 2 shows the puncture mark between the pectoral fins (detailed
in Figure 3), whilst Figure 4 shows a 15 mm puncture mark located below and
anterior to the dorsal fin. The puncture injuries and damage to the skin on the
flanks were probably caused by contact with rocks and other sharp objects when
drifting close to the shoreline, though it is possible they were caused by the
use of a gaff during removal of the carcass from the fishing nets.
Considerable damage was sustained to the beak and lower
jaw (Figure 5), with many broken or missing teeth (Figure 6). Examination of
lower jaw revealed a break across the ramus close to the coronoid process
(Figure 7), which were probably sustained when the dolphin was removed from
fishing gear.
