Choice, In A Predicament Poem by Jayatissa K. Liyanage

Aerodynamically shaped body being
logical locomotary need, most prime
for naturally effective movement of any being
not always obliged; bungled at times, in fixing
to the dismay and disappointment of none

Intermixed laterals with cephalo-caudal parts
On dorso-ventrally pressed and flattened
anterior-posteriorly compressed torso
the Crustacean clan, facing the dilemma,
chose sideways walk, over a volition of extinction
