Nobody knows what the whales may have to click and clack about, but it could be a form of voting-time to stop here and synchronously dive down in search of deep water squid, now time to resurface, move on, dive again. Clans also seem to caucus on which males they like and will mate with more or less as a group and which ones to collectively spurn. By all appearances, female sperm whales are terrible size queens. Over the generations, they have consistently voted in favor of enhanced male mass. Their dream candidate nowadays is some fellow named Moby, and he's three times their size.
