Carcinisation in poetry is a metaphorical or formal process where a poem evolves toward a “crab-like” structure—perhaps through palindrome, reversal, or lateral movement—drawing on the biological phenomenon where disparate crustaceans independently evolve crab-like forms; this neologistic concept might describe poems that mimic recursive, sideways, or armored textual strategies, symbolizing adaptation or defensiveness in contemporary verse.

Process where form evolves toward crab-like symmetry or structure. Applies to palindromic verse or poems that mirror themselves. Related to chiasmus but describes evolutionary formal development.
