Four of the mice that were caught, skinned and
stuffed during
Biota NB 2016.

I learned an important lesson while participating in Biota NB
2016: Do not name the mouse you are about to skin. And then stuff. And then pin
to a board. Do not.
This was certainly not a lesson I ever expected to learn,
but on my second day of participating in Biota NB’s 2016 field season, I found
myself learning just that. And as lessons are so often revealed, I learned it
the hard way.
I had spent the better part of the day in the lab,
photographing the activities going on therein and pestering researchers with
questions. As most of the action was occurring at the small mammal table, under
the leadership of Biota’s small mammal researcher Karen Vanderwolf, I spent a
good chunk of my time there, happily taking photographs and observing from a
distance (emphasis on distance).

I thought I’d gotten away safe. It was nearing dinnertime
and I was wrapping up my notes for the day when, “How about you? Do you want to
skin a mouse?”
No no no no no no no
no no.
“Yes, you do. Here, I’ll show you.”
Rats. Or mice or
whatever.
Now this was definitely not the way I wanted to end the
afternoon, but I also didn’t want to look like a wimp by saying no. So I went
over to the skinning table and sat down.
For those who don’t know me, I’m a pretty soft-hearted
person. I feel bad if I see a loaf of bread lying desolately all by itself
after being knocked off a shelf at the grocery store. I apologize to trees if I
run into them when I walk by. The possibility of skinning a mouse was so far
off my bucket list that you would have needed the Hubble Telescope to see it.
But here I was, joining the Biota “sewing club.”
I was handed a thawed deer mouse (Peromyscus maniculatus) in a clear plastic bag. It was so little
with its fur all spiky and cute. However, it was also cold and clammy.
Maybe this won’t be so
bad after all. The mouse definitely seems dead, I thought. But these
thoughts didn’t last for long when Karen explained to me that the mice we were
skinning and stuffing had been caught that morning. Somehow the thoughts of the
little mouse on the table in front of me blissfully running about just hours
before did little to relieve my already great misgivings about the entire
situation.
Skinning a mouse is a very delicate procedure. First you
have to find the skin under its fur and make a small cut. If you cut too deeply
you’ll just get a lot of blood. I let a little part of me die and made the
first cut. It took a few tries.

This is where things took a turn for the worse. Karen took a
look at my mouse and informed me that it was a lactating female. She handed the
mouse back to me and I looked down at it and … You look like a Phoebe. Hi Phoebe.
Uh-oh.
An impossible task was just made infinitely more impossible.
The skin of a mouse is separated from its flesh by turning
the skin inside out as it is pulled off the body, gently separating the
connecting tissues as you go along. Pull too hard and the delicate skin will
rip. Don’t pull hard enough and you won’t make any progress at all. I was left
foundering in the latter category.
Come on Phoebe, that’s
a girl. I was having difficulty pushing Phoebe’s leg out of the skin.
For some reason I was scared of hurting her. (How was I supposed to skin
something that I kept saying sorry to?) The other difficulty was how sticky the
flesh was. Although there was no blood as long as you were careful (thank
goodness), we had to use corn flour to absorb the fat and any blood that might
be encountered accidentally.

body,

Phoebe’s limbs and face required extra attention. With a
mouse’s limbs, you have to push the limb out of the skin and then cut it at the
ankle/wrist bone. For the face, there are a lot more connecting tissues.
Special care must be taken around the jaw, ears, eyes and snout. I gave Phoebe
up to Karen’s expertise for this part. With a few careful snips, Phoebe’s skin went
over and off her snout and the task of skinning was complete.
Although Phoebe had started out cold and damp, as I worked
at her skin, it became warm and dry. If her skin had not been clearly separated
from her flesh, it would have been easy to mistake her warm skin as belonging to
a living, breathing creature. This is something I tried vainly not to think
about.
Phoebe’s carcass was another story. There it was lying on
the table in front of me. Her little beady black eyes, from which the skin had
been so carefully snipped away, stared up at me. I had to prepare the cotton
stuffing with this pitiful site at the fringes of my vision.

will be taken for further research.

Step two of my ordeal – let’s be honest, Phoebe’s ordeal – was to stuff Phoebe
with cotton. To do this you have to take a thin piece of cotton stuffing and
wrap it around a wire, trying to mimic the shape of the mouse’s body. This part
wasn’t so bad but I don’t think I did Phoebe much justice as she was left
looking a little emaciated.

Once stuffed, the mouse is stitched up with cotton thread. |
The final stages of stuffing a mouse involve putting wires
in the limbs and tail. Once this is done, the mouse is stitched with cotton
thread. I carefully brushed off Phoebe’s skin until it shone again, but to add
insult to injury, I had to pin Phoebe to a board for the last step.
The finished product. Phoebe is in the middle,
now immortalized for further research at the museum. |
Although skinning and stuffing Phoebe was definitely way out
of my comfort zone, looking back on the experience has left me with a positive
final impression (I’m sure being away from Phoebe’s remains helps). First of
all, Phoebe wasn’t trapped and stuffed for nothing. She, along with her body
and tissue and organ samples, will now be stored in the museum’s collection. Ultimately
she will contribute to our understanding of her own species as well as the
greater picture about the diversity of all species in the province. I also now
have a greater respect for the people who have to do things like this often.
The final note I took away from the experience is a personal
one. I will likely never skin another living thing for the rest of my life, but
now I can say that I can do something that I would never have done otherwise –
and I got a pretty cool tale (or should I say tail?) to tell out of it too.
