Abstract
A fundamental question in animal ecology is when and why physiology limits how animals behave, how often they reproduce, and how likely they are to survive. Marine mammals are particularly suited for these studies because their ability to forage underwater is constrained by the size of their tissue heme and O2 stores, and pups are born with very low hemoglobin (Hb) and myoglobin (Mb) levels that can limit breathold…
