Study of body size, feeding rates has implications for ecosystems, food supply
How can blue whales, the largest animals on the planet, survive by feeding on krill, shrimp-like creatures that are the size of a penny? According to UCLA life scientists, it’s all a matter of dimensions.
In findings published May 30 in the journal Nature, the researchers demonstrate for the first time that the relationship between animals’ body size and their feeding rate — the overall amount of food they consume per unit of time — is largely determined by the properties of the space in which they search for their food.
