How would you define hydrophone?

As far as I know, it is a microphone with the proper acoustic impedance match to operate effectively underwater.

The exact composition of the hydrophone can vary widely, piezoelectric, ceramic, etc., but it is still a hydrophone. They can be omni-directional, fixed, or directional (steerable).

You may be entirely correct as I am 20 years out of the service, but I'd hate to think that I'm so far out of touch with current technology that I wouldn't be at least peripherally aware of something which has eliminated hydrophones altogether.
