The chances of finding a large eel in Loch Ness are around 1 in 50,000 for a 1-metre creature. Researchers at the University of Otago looked at the DNA of Loch Ness inhabitants, concluding that perhaps sightings of Nessie were actually large eels. But now, data scientist Flow Foxon says eels don't get that big. Professor Neil Gemmell is the AgResearch Chair in Reproduction and Genomics at the University of Otago. Neil joins the programme to discuss.
