Marine
mammals such as whales utilize sonar to communicate,
find their food, and to understand where they are.
Similar to bats, they live in conditions where visual sight is not too effective. In the deep ocean whales and other marine mammals need the use of echolocation to survive.
Blue whales specifically can process frequencies much lower than human. They communicate in what is called the infra-sound range, which includes frequencies lower than approximately 20-30 Hz.

Dolphins use high-frequency 'clicks' to find food and navigate through dark waters. The dolphins receive echoes from their clicks and are able to determine what is in the waters around them.
Dolphins can process frequencies in higher ranges than humans, much like bats. They communicate in what is called the ultra-sound range, which includes frequencies higher than approximately 18k-20k Hz.
