Deeper dives are linked to longer surface recovery in sea lions

Sea lions, marine mammals belonging to the eared seal family, have to dive to search for food and other resources. Between dives, however, they return to the surface to breathe and recover. A new study suggests that deeper dives are linked to longer surface recovery times in these animals. This could have implications for their energy expenditure and overall health, which in turn may affect their ability to survive and reproduce.
