We investigate the evolution of marine mammals using data from fossils, anatomy, and ecology to answer questions about the origin and fate of these amazing organisms.

Whales are big, but why aren’t they bigger? It turns out that one of the fundamental limits for whales has to do with the energy they get from their prey and the ways that they feed. Led by Prof. Jeremy Goldbogen (Stanford University), Dr. Pyenson and two dozen other scientists analyzed tag data from over 10,000 feeding events across 11 different species, from harbor porpoises to blue whales, to show how the return on energy from feeding ultimately constrains how big whales can be. Their paper was also featured on the cover of the prestigious journal Science (using the same photo from the hardcover edition of Spying on Whales)!
