Re: Sensors Fr: [FT] Simultaneous Fire

G'day,

That's cool wasn't real clear I guess ;)

 >So do the Zooplankton make noise or something?

Well some species can release gas bubbles and can "click" etc which
makes 
them easier to find in the first place, but to be honest I think a lot
of 
the tracking would be the equivalent of "active" sensors (specific 
frequencies pick out different species...low for animals with air
bladders 
inside, high for deep sea fish and other animals with no air bladders).
So 
now I'm probably confusing some of the content/argument of earlier posts

about which was easier for use in identification, sorry.

Cheers

Beth
