The Bananafish

A popular fish in some schools the deep
sea swallower called the bananafish:
Sansjawdsalumpigus.
Though it lives on the floor of the aphotic zone,
it is not bioluminescent; in fact, it’s invisible.
Rising to the surface with changes of tide, mind,
and mood, it’s worse by tens than the burbling
Jabberwock. A bananafish is never caught;
it slips you, and you are capsized.

The bananafish sees without eyes things
that disappear, hears sounds in the depths
of silence, lives on even when squished
or peeled or baked into bread or spread
in undigested seeds. They live in clusters,
but it only takes one to upend your plans
for a day, a week, or a lifetime. Nevermind
the Jabberwock; beware the brilliant
brainy glare of the bananafish.

What bites but has no teeth?
What smells but has no nose?
What swims without fins,
goes loopy if left to shelf,
barmy as the froth of beer?
Ans: the double-dealing
bluff bunko, the sly hoax
of Sansjawdsalumpigus,
commonly called the bananafish.
