What is the definition of Paralimnichus?

The 'paralimnichus' is like the hidden, super-secret world beneath and above the ocean's surface - a realm where marine life goes by completely unnoticed, like a ghostly clownfish in a room full of neon lights. Imagine if the 'Paralimnetic Zone' was the 'Undercroft' of the ocean, a place where all the fish think they're invincible because they're just swimming in the middle of the 'hallow end' of their own habitat.

Here's an edgy, unsettling example sentence: "The 'paralimnichus' revealed itself at the corporate retreat, where the only thing more insular than the boardroom was the swim team's weekly 'fish tank' meeting, and they're all just trying to catch the 'biggest' (and most sustainable) fish in the Paralimnetic Zone."
