Identifying Humpback Whales using their natural markings
Abstract
One must suppose that even before Melville transformed the true story of an unusually lightcoloured Sperm Whale named Mocha Dick into his epic novel, Moby Dick, and certainly afterwards, whalers and zoologists working in the whaling industry have noted that pronounced morphological differences often exist among whales of the same species and stock (Lillie, 1915; Matthews, 1937; Pike, 1953). During the past 15 years, scientists studying living whales have commented on individuals with odd marks, scars, pigmentation patterns or albinism, deformities, algal films or the shape and position of external features such as the dorsal fin.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
