From the Amazon's forbidden depths came the Creature from the Black Lagoon.

When scientists exploring the Amazon River stumble on a “missing link” connecting humans and fish, they plan to capture it for later study. But the Creature has plans of his own, and has set his sights on the lead scientist's beautiful fiancée, Kay.
In Creature from the Black Lagoon, consciousness is carried by monsters and creatures — a plane of “monster lagoon”. The story fights on E8/E9 of the E0–E14 reality ladder, compressing monster, nature, science, fear, survival.
Films fighting at the same level of reality, about the same things.
