Morphology

passive + electrolocation

This is a straightforward adjective + noun composition: 'passive' (not actively producing/responding) modifies 'electrolocation' (detecting/locating with electric fields), so the phrase denotes electrolocation that occurs without actively emitting signals. The overall meaning—detecting external electric fields in a passive way—is directly derivable from the constituent meanings.

Etymology

Passive electrolocation comes from passive (not giving out a signal) and electrolocation (using electricity to find things). Think of a fish as a living antenna with tiny sensors that feel electric fields in the water made by other animals or objects, so it can 'detect and locate' them without making its own electrical signals.
