Where can I find a list of species that

magnetite in their bodies? Preferably
(in the case the former) with a
per-mass estimate.
Which species? I am interested in
everything except plants but I'll take
what I can!

If I remember correctly, SRI International (formerly Stanford
Research Institute) Life Sciences Division was engaged in research
in magnetostatic bacteria in certain birds.
I don't remember much about this, but a letter to the division might
uncover some references.

Good luck!

PS: I have always been interested in animal navigation, especially
those species who travel thousands of miles and return to a
particular nest or (in the case of fish) to a particular small
stream.
I work with Mirounga angustirostris -- the northern elephant seal --
who travel from the beaches of California to their feeding grounds
in the Aleutian islands and then come back to the same beach year
after year.
Having a magnetic compass would help, but is certainly not
sufficient for long range navigation. Could you find your way from
the Aleutian islands to a small beach in northern California with
nothing but a compass?
I don't think so!
