An ectotherm is an animal that obtains body heat from their environment. Since they do not maintain their body heat through metabolism like endotherms, their internal temperature varys with their environment. Reptiles, amphibians and fish are all ectotherms.

The sky is a normal color almost.
Three days ago a cloud slid over it
like a strange tongue,
green, I was sure,
like everything else.
The money we burned for heat;
our skin.
Does your voice still work?

I remember when the first shining shell
pierced the atmosphere -
How you muttered "earthquake weather."
Your lips started cracking when the television
died.

They'll take me first.  I keep glancing
in the mirror:
my coccyx.
I touch its scales, thinking
you might find it
impressive when it's done growing
if they keep us together
