    Item type: Journal Article • Journal: African Journal of Marine Science
    The species richness, spatial distribution, seasonality and interspecific associations of cetaceans in tropical oceanic waters between the Gulf of Guinea and Angola were examined using 5 905.3 h of dedicated survey effort collected from 13 platforms of opportunity (geophysical vessels)...
  3. Cetacean research in the southern African subregion: a review of previous studies and current knowledge

    Cetacean research in the southern African subregion: a review of previous studies and current knowledge

    Item type: Journal Article • Journal: African Journal of Marine Science
    Cetacean research, in terms of the number of papers, and areas for which data are available, has expanded considerably in the southern African subregion in the past decade, especially in the South-West Indian Ocean. We review cetacean research within this...

    Distribution, behaviour and photo-identification of Atlantic humpback dolphins <em>Sousa teuszii</em> off Flamingos, Angola

    Item type: Journal Article • Journal: African Journal of Marine Science
    Atlantic humpback dolphins Sousa teuszii are a priority for research due to their restricted geographic range, narrow ecological niche and the paucity of existing information. The distribution and behaviour of S. teuszii off Flamingos, southern Angola, was investigated during summer...

    Blue whales <em>Balaenoptera musculus</em> off Angola: recent sightings and evaluation of whaling data

    Item type: Journal Article • Journal: African Journal of Marine Science
    The population of blue whales Balaenoptera musculus inhabiting the South-East Atlantic (Gabon to South Africa) was heavily depleted by commercial whaling. We report four photographically-verified sightings, and one probable sighting, of blue whales in deep waters (>1 000 m) off...
