Natural mortality of puffadder shysharks due to Cape fur seals and black‐backed kelp gulls at Seal Island, South Africa
Abstract:Natural mortality of puffadder shysharks Haploblepharus edwardsii due to two species of marine tetrapod, the Cape fur seal Arctocephalus pusillus pusillus and the black‐backed kelp gull Larus dominicanis vetula, is reported. These data constitute the first multiple observations of natural mortality of any cartilaginous fish due to object play or kleptoparasitism by marine tetrapods. Evidence of range extension of the puffadder shyshark to False Bay, South Africa is presented.
