Diagnostic Description

fornì da FAO species catalogs
Adult male ginkgotoothed beaked whales are dark grey, with light spots; females are apparently lighter. They do not appear to be as heavily scarred as most other mesoplodonts. The throat grooves, dorsal fin, and tail flukes are typical for Mesoplodon species. Bulls have flattened tusks that barely break the gumline, slightly behind the middle of the lower jaw; erupted teeth are absent in females. Can be confused with: The uniform dark pigmentation, small posteriorly placed teeth, and paucity of characteristic ziphiid scars may allow a tentative classification of adult male ginkgo-toothed beaked whales. Otherwise, this species will be virtually indistinguishable from other species of Mesoplodon.
