#2Here's another story/fact that should be included.
There's a species of octopi that live in groups. On nights with bright moon, predators can identify them because they cast a shadow. They have evolved an organ to intake particular bacteria that use what's called quorum sensing to detect when there's enough of them around. When the organ is full of these bacteria, the bacteria glow and therefore stop the shadow of the octopi. It's a great example of symbiosis, more specifically mutualism of two species. The octopi get saved and the bacteria get a safe place to live.

#4Most all waves glow at night. But to see it with the naked eye you need proper darkness. Ocean + waves + darkness = bad idea. So i cannot suggest anyone go looking for this.

The squid symbiosis is mentioned in the article. Oh and btw, it's octopuses or octopodes (greek not latin, fyi).

Actually it's English, where octopi is a perfectly acceptable and widely-understood plural.

What's popular isn't always correct and dictionaries by definition reflect usage.
That is unless it doesn't literally kill you that literally now actually means figuratively too.
