Moby dick is the most famous fictional whale.
As in the book, here in Steemit people is trying to hunt one of those very rare enormous white whales but this specie is very hard to find and still everyone wants to hunt one.
It is said that those whales are worth thousands of upvotes and give their shit is sold for a huge amount of money (for real, whale shit is worth thousand of dollars).
Here you can see some people trying to hunt the White Whale down. You can see other upvotes in front of the whale's nose.
Those creatures are extremly rare to find and when one is found it is usually surrounded by thousands of other fishermen that are trying to hunt him down, that is why it is so important to draw the attention of the whale which can be achieved in different ways.
People trying to draw the attention of the whale (unsuccessfully).
Some people think that you can made a whale bait the hook and they use clickbait titles, others think that they can be summoned by dolphins and some others think that whales do not exist.
The truth is that whales are clever and silent animals, so you can probably sail near one and you won't notice anything.
Whales only show theirselves when they see a good fisherman and they show them their gratitude by giving them a bit of whale shit (someone trash is others' treasure).
