The Caribbean hermit crabs in Anna-Sara Krång’s laboratory are no picky eaters. They are eager to gobble down any fruit, nuts, fish or coconut flakes that comes their way.

All in all, five different lineages of carnivorous mammals evolved sabertooth dentition: the ancient creodonts, marsupials and three different lineages of true cats and cat-like [...]
