In the conversation about jellyfish, the speaker expresses their fondness for these creatures, describing them as cute. This admiration prompts a deeper reflection on the nature of perception and reality. They suggest that our everyday view of the world is limited, as we often forget the vastness of what exists beyond our immediate surroundings.

The speaker highlights that humans only observe the surface of the ocean, which covers two-thirds of the Earth's surface. They point out that this surface is merely a thin "skin" over a much more complex and mysterious realm inhabited by jellyfish and other beings. This notion serves as a reminder of the unknown depths that lie beneath, encouraging a broader understanding of the world beyond what is superficially visible.
