I think &amp;quot;shadow biosphere&amp;quot; is currently pretty loosely defined and not widely accepted by academics, and it seems to refer simply to organisms that might exist but are not currently being studied widely. In fact to me, the use of the term &amp;quot;shadow&amp;quot; in the name is relatively misleading and simply refers to a possible case of something not understood and/or studied at length, not that it's invisible. Randall appears to be making fun of the name by suggesting it means invisible to normal life as we know it. The title text further pushes this pun by suggesting that a coating of &amp;quot;desert varnish&amp;quot; makes normally visible objects become invisible, as with the buildings where shadow biologists carry out their work. Desert varnish is in fact visible when it is found in appropriate locations on normal objects like rocks - it does not make the rocks invisible! Somehow, I think these ideas need to be incorporated into the explanation.

I think &amp;quot;shadow biosphere&amp;quot; is currently pretty loosely defined and not widely accepted by academics, and it seems to refer simply to organisms that might exist but are not currently being studied widely. In fact to me, the use of the term &amp;quot;shadow&amp;quot; in the name is relatively misleading and simply refers to a possible case of something not understood and/or studied at length, not that it's invisible. Randall appears to be making fun of the name by suggesting it means invisible to normal life as we know it. The title text further pushes this pun by suggesting that a coating of &amp;quot;desert varnish&amp;quot; makes normally visible objects become invisible, as with the buildings where shadow biologists carry out their work. Desert varnish is in fact visible when it is found in appropriate locations on normal objects like rocks - it does not make the rocks invisible!

I think &amp;quot;shadow biosphere&amp;quot; is currently pretty loosely defined and not widely accepted by academics, and it seems to refer simply to organisms that might exist but are not currently being studied widely. In fact to me, the use of the term &amp;quot;shadow&amp;quot; in the name is relatively misleading and simply refers to a possible case of something not understood and/or studied at length, not that it's invisible. Randall appears to be making fun of the name by suggesting it means invisible to normal life as we know it. The title text further pushes this pun by suggesting that a coating of &amp;quot;desert varnish&amp;quot; makes normally visible objects become invisible, as with the buildings where shadow biologists carry out their work. Desert varnish is in fact visible when it is found in appropriate locations on normal objects like rocks - it does not make the rocks invisible! Somehow, I think these ideas need to be incorporated into the explanation.
