Study show that South Africa's white sharks face genetic threat

According to research conducted by Stellenbosch University, South African white sharks are facing a unique genetic threat - their low levels of genetic diversity means their capability to survive into future is seriously endangered.

CapeTalk’s John Maytham spoke to Dr Sara Andreotti, lead researcher about the findings to the research.

Listen to the full conversation below:

According to Dr Andreotti, the South African white sharks were compared to Australian white sharks and Californian.

We are supposed to have a lot of lineages in a population but we could only find 4, compared to Australian population where they have 23 and Californian sharks have up to 40 lineages.
