4- Big Blue

Original air date: 19 November 2017

Below is an experimental view of the above. Since the blue colour is reserved for web links it is out of the question and was replaced with green which is used for three different purposes in the listing: for Theme, contents column it is used to mark the contents (usually a short for the detailed description in the right column). It can also be used in the right column as a connecting text between two different – otherwise seemingly inconsistent – stories. Lastly it can be used to indicate filming location.

Then there is an explosion: some shoal of tiny fish coming to the surface to spawn
