We've had a Woodhouse's Toad
(Bufo woodhousii) living on our property
for at least 15 years. They can live up
to 20 years, or more, in the wild...
possibly longer.
The size of my palm, with wrinkly brown/grey
skin, and looking somewhat prehistoric, s/he is
very beneficial at keeping insect populations
in check.
Planning for a larger painting in this toad's
honor, I've been doing some sketches to
work out the details.
