as well as allowing more accurate population predictions by simulating the mark-release-recapture technique. A photographic catalogue of all known whales in the North Atlantic was developed over this period and is currently maintained by Wheelock College. Similar photographic identification projects have ...
To date, 113 tissue samples and 699 identification photographs of humpback whales have been collected in the water of the eastern Comoros Archipelago and contributed to photographic and genetic archive for C2. Eighty whale have been genetically identified and as many as 250 have been photographically...
We have five ongoing research programs including a photo-identification survey commenced in 1992 to provide data for the study of the behaviour, social dynamics and ecology of the eastern Australian humpback whales. Our behavioural data and photo-id fluke catalogue have already made a significant con...
where researches photographed its tail fluke andtook skin sample to determine the animal's sex. Two years later a tourist on a whale-watching boat snapped aphoto of the humpback near Madagascar.To match the two sightings, Stevick's team used an extensive international catalogue of photographs of...
Subspecies recognition can affect how people (scientists and non-scientists alike) view organisms and thus has important implications for research on, as well as the conservation of, these entities. Recently, a small group of Indo-Pacific humpback dolphi
. In total, 67,512 song units were classified into 15 distinct unit types, plus seven subtypes, and 13,787 phrases were classified into 114 distinct phrase types (see supplementary materialIIfor catalogue of unit and phrase types). The level of agreement between the manual unit classification ...
Humpbacks are often catalogued based on the distinctive features seen on their tails or dorsal fins. They are nicknamed based on these features for the “practical purpose” of identification and also for deeper purposes of conservation.
Seven whales were resighted (22.6%) to Pacific Whale Foundations' 'Breeding Stock E/Area V Humpback Whale Catalogue'. Thirty percent of the groups observed during surveys contained newborn calves indicating this region may be an important nursery area for Breeding Stock E1 humpback whales. The ...

These fluke photographs have been compared to over 6,500 individual fluke photographs maintained in the North Atlantic Humpback Whale Catalogue. Based on photoidentification, humpbacks in the Cape Verde Islands have a relatively high interannual resight rate (> 22%) compared to other studied breeding...
