Diversity and evolution of New Zealand’s marine mammals

Te Papa researchers: Felix Marx and Alan Tennyson

New Zealand waters abound in marine mammals, from nearly half the world’s species of whales and dolphins to fur seals, sea lions, and a smattering of (sub)Antarctic seals. We study fossils and living marine mammals to elucidate their diversity and evolution through deep time. Combining anatomy and DNA, we investigate how different species are related to each other, and how, when and why they diverged.

Our work focuses on New Zealand and the Southern Ocean, but the highly mobile nature of marine mammals often means that we collaborate with researchers from around the globe.
