Whale

Whales are available in worlds with particularly rich environments, and along with chimaeras are one of the only frenzy animals that cannot be automatically produced. They become available for purchase after researching Cetacean Awareness provided you have at least 100,000 fish. Their description is "Persuade one of the great whales to help us out. They can round up entire schools."

Career Path
Whales have the option of forming a Whale Chorus after researching Eternal Song. This is the only way Essence can be accumulated without passing through the Gateway. Only one whale chorus can be formed, but it can be boosted with various artifacts.

Laboratory Research
There is 1 upgrade that can be researched that is specific to only whales and 2 upgrades specific to all cetaceans. The following research is available in every world in which whales can be found: {| class="article-table" ! scope="col" |Upgrade ! scope="col" |Description ! scope="col" |Result ! scope="col" |Cost

Cetacean Awareness
From a distance, it's harder to tell which of us are really sharks or... those other things. We need to figure this out. Whales and dolphins are twice as effective, now that we can adapt our hunting strategies to their supposed 'strengths'. Whale power x2

Eternal Song
The whales claim to know segments of some form of ancient ethereal music that connects worlds. We can collect what they know to piece it together ourselves. A chorus of whales can be assembled to sing the eternal song, but we have no clue what it will do.

Primordial Song
Even the dolphins can remember an ancient song. The whales know more, but it stirs within both of them. Dolphins and whales, and their roles, are all four times as effective. The song of the ocean is older than life itself. Whale power x4

Story
Warning: This section includes speculation, as canon answers don't yet exist. Keepers of song and mystery.

Little is known about the whales, who seem to do little other than sing. They are huge and mysterious, and know more than they say. Given their ability to gather Essence, it appears they may have passed through the Gateway before themselves. Their kind is ancient, and they’ve passed their knowledge down through the generations.

Trivia
The blue whale is not just the largest mammals alive, but the largest animal ever known. There is some disagreement as to whether this record should be based on length or mass, but an adult blue whale can measure up to about 100 feet in length and 200 tons. In comparison, arguably the largest prehistoric animal known to man was about 120 feet long and 70 tons. In any case, the size of these animals is unprecedented in sea creatures. The nearest non-whale competition in history is the megaladon at perhaps as much as 54 feet long. The nearest alive today is the whale shark, which can reach at most a modest 40 feet.
