Beaver

A

 web-throttled aquatic
coat-floating rodent with
a counter-current heat deterrent
flat tail leather strap
drop-prop rudder that slaps
ripples under water drizzle:
a potent icon of the Holarctic
sporting iron orange incisor chisels
felling forest to lodge in flora;
second largest to the capybara—
an anal-preening submarine
enduring by eating tree bark,
that guards by marking lasting tracts
with urine fluid from castor sacs.
