Amistad Gambusia
Gambusia amistadensis
To obtain the perfect idea
of nothing, the Puritan minister Jonathan Edwards wrote,
“we must think of the same
that the sleeping rocks dream of.”
Here, lined up on my windowsill:
nine gray rocks, faceted with pale yellow
and orange, powdery to the touch
and warm from the sun.
With equanimity, light pours through
the window onto all of them.
If they dream of you
then I can’t write about you
without writing about them, because no one else
can play their part, glossily lining
the bottom of Goodenough Spring,
the West Texas creek where you dart
like a shard of filigree, unblinkingly
swimming in a body
of water probably named for a family
with an old English name originally used
for someone whose accomplishments were average.
Gambusia, your name,
comes from the Cuban Spanish word
for nothing.
May I call you
Nothing. There is no hurry for you
to answer, or tell me which
is sadder: the dreams of rocks
or speaking to nothing.
The size of an ocotillo spine, you’re too small
to be fished for sport, not even the way
I’m fishing now, flipping through natural histories
for a mention of you, expecting a glint
of iridescence to swim up from an index.
In the heat of this devastating summer,
you seem as diminutively monumental as a glass paperweight
pinning down notes about the difference
between erasure and banishment
and yes I meant to write vanishment and now
I want both. When you appear
in Vanishing Fishes and Battle Against Extinction
you remind me that vanishment
can be conferred, like the language
of war, even onto a weaponless minnow
who weighs less than a bookmark.
When engineers build a dam across the Rio Grande
connecting Mexico and the United States
and name it Amistad, the dam becomes a symbol
of friendship, but when the Rio Grande is dammed,
water rises in Goodenough Spring, knocking
the stones shining under you,
churning and turbid and suddenly flooding
the creek, confluence, and headspring
that sustain a single species of gambusia
no one knows about
until 1968, post-dam, mid-flood, too late,
when ichthyologists discover you
darting through the suddenly flooding ocotillo
and prickly pear cactuses as water rises
over the riverbanks.
The scholarly paper that declares your discovery
declares your endangerment, and the authors
net and transfer you to a field laboratory
in Austin. Later, they move you to the Dexter National Fish Hatchery
in New Mexico in the 1970s and 80s
because you have “no historic habitat
remaining in nature” and there, in tanks, you go
full ghost.
May I call you extinct?
I was the second-to-last person
to see them alive,
says the ichthyologist in the museum I visit,
handing me a warm jar of you
jostling together in formaldehyde.
The last person to see you alive
is dead. I put you back
in the ichthyologist’s hands, he puts you back
at the back of a warehouse shelf. You’re removed
from the endangered species list
when I’m eleven, the same age
my twin daughters are now, now watching
the ocean throw thousands
of fish onto the Texas Gulf Coast. Take them,
the ocean seems to say, and not kindly, because
they’re dead, mostly asphyxiated
Gulf menhaden silvering the sand with the last
of their dazzle.
I once had a teacher
who asked me, What is another word
for lostness? I used the word too much.
I don’t remember my answer, lost now,
a little nothing to line up on the windowsill
next to the rocks, two seed pods, a burr,
one lobe of a tiny white mussel shell
with a buttery interior, and two vials
of water from the Amistad Reservoir
that a friend collected from your demolished habitat
to help me think of you, a fish named
for the dam that obliterated you.
What did it feel like
to lose your only home
is a question you do not have to answer.
After all, I am not your teacher.
An urgent message from the Editors
As the editors of The Nation, it’s not usually our role to fundraise. Today, however, we’re putting out a special appeal to our readers, because there are only hours left in 2025 and we’re still $20,000 away from our goal of $75,000. We need you to help close this gap.
Your gift to The Nation directly supports the rigorous, confrontational, and truly independent journalism that our country desperately needs in these dark times.
2025 was a terrible year for press freedom in the United States. Trump launched personal attack after personal attack against journalists, newspapers, and broadcasters across the country, including multiple billion-dollar lawsuits. The White House even created a government website to name and shame outlets that report on the administration with anti-Trump bias—an exercise in pure intimidation.
The Nation will never give in to these threats and will never be silenced. In fact, we’re ramping up for a year of even more urgent and powerful dissent.
With the 2026 elections on the horizon, and knowing Trump’s history of false claims of fraud when he loses, we’re going to be working overtime with writers like Elie Mystal, John Nichols, Joan Walsh, Jeet Heer, Kali Holloway, Katha Pollitt, and Chris Lehmann to cut through the right’s spin, lies, and cover-ups as the year develops.
If you donate before midnight, your gift will be matched dollar for dollar by a generous donor. We hope you’ll make our work possible with a donation. Please, don’t wait any longer.
In solidarity,
The Nation Editors
