Underwater intelligences

If you're interested in the prospect of underwater intelligences, Jose, you'll enjoy James Cambias' story "The Ocean of the Blind," on our syllabus later in the semester.

Of course, intelligence is not necessarily a survival trait. Witness the cockroach. It may inherit the Earth yet.
