In quiet locations, over 40% of clicks identified in porpoise monitoring occur as click trains. Similar rates can be found from dolphins in such quiet locations as the Amazon. More typically, in dolphin monitoring, less than 5% of the clicks are in trains. This is because their clicks are less distinctive, so more non-cetacean clicks are logged at the maximum bandwidth required to include the cetacean clicks and because more echoes and multi-path duplicates of clicks are received from these louder animals.

Sperm whales, Physeter catodon may be difficult to monitor, although monitoring has not yet been tried.
