messages from below

the radio signals emanated from the depths
commuters puzzled over the whistles and squawks
that cut through their favorite programs
cryptologists went to work

but the waves soon turned to beams
tunnels of coded energy
aimed not at humans
but at a point somewhere near Wolf 359

first assumed to be a submarine human colony
but scans showed no excess carbon emissions
so dolphins were next guessed to be the cause
no one suspected the humpbacks

as the oceans acidified and the air warmed
the whales were busy
at last their solar ships rose from the sea
and the whales ascended

as if rungs laddered from deep to deep
born of the sea they swam among stars
