Distrust Mars Fish Counting Effort

Who
knew there were fish on Mars?  And we should distrust their efforts
to be counted? I’ll have to start keeping a closer watch on the news….

On land the demand is to know, with certainty, how many fish are left
in the waters, and how many there will be. But answering such questions
requires getting to know cod. And this ancient animal, with its thick
speckled body and glassy eyes, has proved an elusive acquaintance, even
for specialists.

The Stellwagen habitat, captured with a robotic underwater camera, provides
a glimpse of the sheer enormity of the challenge.
