Inductors Found In Nature

A snook or raballo can detect stuff with the prominent "lateral line" on its side.

Everything has resistance.

Is there a single example of an inductor in Nature?

There aren't any fully rotational items, roller bearings, dynamic seals etc., in nature partly because it would be hard to supply nutrients.

A coil might be a different story.

Knowing a bit about lateral line organs, I fail to see the
connection between these statements. Please clarify!

many examples. ANY conductor longer than wide is an inductor.

Well except for Flagellum.

A cool little rotating motor.

An inductor should be duck soup.

And what does *that* have to do with either lateral line
organs or inductors?

The essence of an inductor is basically inertia-like. In a
lateral line organ (or in the cochlea or semicircular canals
of the ear) there is fluid motion which has inertia, but as
far as I know this is something that the system has to
compensate for, not a feature that it depends upon for
operation.

In the case of the semicircular canals, the fluid motion may serve as a
gyro. I think it does, in fact.

There are gyros used in aerospace applications that, once you pull away
the surrounding circuitry and support mechanics, are a tube of fluid with
a directional velocity sensor. They deliver a signal that's essentially a
high-pass filtered rotation rate, with a knee that depends on the fluid
viscosity and fluid path smoothness.

Many; an aurora borealis is basically a low-pressure discharge
lamp and a transformer-like winding, around a changing magnetic flux.
