While studying pygmy and dwarf sperm whales, a researcher involved in a new project stated that 'understanding what resources support populations of these incredibly rare animals is important to conservation. If there are changes in the environment or their prey, we can now hope to better anticipate the potential impacts. There had been quite a knowledge gap about these animals, but this work gives us an idea of their ecological niche and requirements in the current environment.'
