  1. A new species of electric ray of the genus <em>Narcine</em> Henle, 1834 from the South-Western Indian Ocean (Chondrichthyes: Torpediniformes: Narcinidae)

    A new species of electric ray of the genus <em>Narcine</em> Henle, 1834 from the South-Western Indian Ocean (Chondrichthyes: Torpediniformes: Narcinidae)

    Item type: Journal Article • Journal: South African Journal of Marine Science
    A new species of electric ray of the genus Narcine Henle, 1834 is described from seven specimens collected from two localities off the western coast of Madagascar, in the Moçambique Channel. Narcine insolita, sp. nov. is distinguished from all other...
  2. Tube-forming polychaetes enhance invertebrate diversity and abundance in sandy sediments of Mozambique, Africa

    Tube-forming polychaetes enhance invertebrate diversity and abundance in sandy sediments of Mozambique, Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    In marine soft-bottom systems, polychaetes can increase habitat complexity by constructing rigid tubes (e.g. several onuphid species) that contrast with surrounding topographically flat sediments. These structures can provide predation refuges and increase larval settlement and thereby increase the richness and...
  3. Migrations of humpback whales past Cape Vidal, South Africa, and an estimate of the population increase rate (1988–2002)

    Migrations of humpback whales past Cape Vidal, South Africa, and an estimate of the population increase rate (1988–2002)

    Item type: Journal Article • Journal: African Journal of Marine Science
    Shore-based surveys of migrating humpback whales Megaptera novaeangliae were undertaken from Cape Vidal, northern KwaZulu-Natal, South Africa, each year between 1988 and 1991, and in 2002. Daily observations of migrating whale groups were carried out from an approx. 60 m-high...
  4. Dugong abundance and distribution in the Bazaruto Archipelago, Mozambique

    Dugong abundance and distribution in the Bazaruto Archipelago, Mozambique

    Item type: Journal Article • Journal: African Journal of Marine Science
    Despite the distribution of dugongs Dugong dugon ranging across nearshore waters of the tropical and subtropical regions of the Indian Ocean and western Pacific Ocean, their distribution in the western Indian Ocean is highly fragmented and appears to be declining...
  5. Baseline assessment of high-latitude coral reef fish communities in southern Africa

    Baseline assessment of high-latitude coral reef fish communities in southern Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The Western Indian Ocean (WIO) is a region where detailed coral reef fish research has been relatively limited. This study constitutes an assessment of the fish communities of seven southern African high-latitude coral reefs. The aim was to provide ichthyological...
  6. First record of <em>Mesoplodon densirostris</em> (Blainville 1817) from continental East Africa

    First record of <em>Mesoplodon densirostris</em> (Blainville 1817) from continental East Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Blainville's beaked whale Mesoplodon densirostris is one of the most widely distributed members of the family Ziphiidae (the beaked whales). However, its exact distribution in many parts of the world remains unknown. On 24 November 2004, the partly skeletonised carcass...
  7. Composition of elasmobranch landings in Bahrain

    Composition of elasmobranch landings in Bahrain

    Item type: Journal Article • Journal: African Journal of Marine Science
    The first detailed elasmobranch fisheries data for the Kingdom of Bahrain are presented, based on surveys of fish markets in April 2012. At least 25 species were recorded, including undescribed taxa. The milk shark Rhizoprionodon acutus was the most frequently...
  8. Non-random habitat use by coral reef fish recruits in Mafia Island Marine Park, Tanzania

    Non-random habitat use by coral reef fish recruits in Mafia Island Marine Park, Tanzania

    Item type: Journal Article • Journal: African Journal of Marine Science
    The habitat use by nearly 3 000 reef fish recruits, comprising 56 taxa, at seven sites in Mafia Island Marine Park, Tanzania, were examined. The study was carried out following the 1998 global coral bleaching event and all sites but...
  9. Estimation of size at first maturity in two South African coral species

    Estimation of size at first maturity in two South African coral species

    Item type: Journal Article • Journal: African Journal of Marine Science
    The corals Acropora austera and Platygyra daedalea have been the subject of extensive reproductive and population genetic studies in the iSimangaliso Wetland Park (iSimangaliso), on the KwaZulu-Natal coast, eastern South Africa. Despite this, estimates of size at first maturity in...

    Benthic macroinvertebrate assemblages in mangroves and open intertidal areas on the Dar es Salaam coast, Tanzania

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The assemblages of benthic macroinvertebrates in mangroves and open intertidal areas of the Dar es Salaam coast, Tanzania, was investigated in 2013–2014, revealing 56 species. Higher density, species richness and diversity were recorded in open intertidal areas, compared to nearby...
