Amazing Archer!

Hawkeye of the world of fishes,
powerful arrow rarely misses:
looking out from under water
somehow knows just where it oughter
aim its powerful water jet
its food to hit, dislodge to get
(despite the water-air refraction
of light – it makes the compensation
for that and arrow’s down-curved path
caused by gravity of earth),
tongue pressed hard against the groove
filled with water in the roof
of its mouth, it pulls its gills in,
shoots the water – powerful spitting!
then, with super-fast reactions
and trigonometric calculations
arrives a fraction after impact
of the dropping little insect:

little fish could not compete
if all these skills were not complete –
not brought about by stray mutations,
but well-designed – congratulations!
