WHAT DOES IT MEAN WHEN FISH FORGET?

by Mary K O’Melveny


This summer, Florida’s ocean water temperatures exceeded 100 degrees Fahrenheit. A recent scientific study revealed that rising water temperatures can cause crucial memory loss to damsel fish and other reef-dwelling species. The fish in the study who were subjected to temperatures as high as F 89.6 did not fare well, failing “to find shelter, recognize their neighbors or find food easily.” —The New York Times, August 23, 2023

As Fahrenheit rose, some damsel fish forgot 
where to find their food sources. With each degree,
memories shifted far away. First to go: 
 
finding a meal. Next was fear. Who posed a threat. 
Where danger lay. Which reefs might safely hide 
them, what might portend trouble in sargassum 
 
seas or bubble upward in their pathways 
turning marbles of algae into floating 
spectral groupers or snappers. As memory
 
fluttered away like flotsam, reef fish failed 
to thrive, survive. Each day’s heightened heat seared
off some tiny thought, some echo 
 
that time had taught, some souvenir of before.
Yesterday’s cache of jeweled thoughts scattered
now into a vast void. Who can ever 
 
truly know what is lost as heat sears, scalds?
As oceans warm, equal risk befalls both 
predators and prey. Who will remain alive 
 
as seas simmer and pale coral reefs blanch
white as brides? Will these warmed fish discard scales
of azure, sapphire, magenta, or wispy 
 
tails of sunshine yellow, peachy orange?
Will they recall where eggs were laid or where 
sharks stayed hidden as reefs shrank? What tales
 
will they recount as awareness shapeshifts, 
then fades away like images in an infinity 
mirror? As they spin through steamy waters,
 
adrift in the present tense, our questions
float along beside them. Will we have a future?
What flashbacks will follow Fukishima?
