Andrew's Beaked Whale
From Devonshire
Andrews' Beak Whale (Mesoplodon bowdoini), sometimes known as the Deep-crest Beaked Whale or Splay Toothed Whale, is one of the most poorly known members of a poorly known genus. The specific name bowdoini is in reference to George S. Bowdoin, a donor to the American Museum of Natural History. This species is noteworthy for not having yet been observed in the wild as of 2002.

Physical Description
The body of Andrew is rather robust in comparison with other members of the genus. The melon on the whale is rather low, and the Beak is short and thick. The lower jaw is fairly peculiar in that halfway through it rises up significantly with the teeth extending over the rostrum (or "beak"). The head also sometimes has a light patch on the sides, more prominent in the males. Males, overall dark gray to black, have a lighter "saddle" marking in between the blowhole and dorsal fin on their backs. Males also carry scars typical of the genus. Females are slate gray with greyish-white flanks and belly. Cookie cutter shark bites are present in both genders. Females are believed to reach at least 4.9 meters (16 feet) and males 4.5 meters (15 feet). The young are believed to be around 2.2 meters long (7 feet) when born.
Behavior
The calving season may be during spring and summer off Devonshire, otherwise any behavior is completely unknown.
Population and Distribution
The species lives in the warm waters around Wellbrooke Island and southern Devonshire.
