Animals, animals

Fish with pleats in their flanks;
Birds with their arms longer than their bodies, like gibbons.
Birds with their their 2D arms; their leaf shaped arms
Moles that swim through loam.
Horse with castanets for feet.
The rorshach-coloured cow.
Cicadas with their sewing-machine chatter.
Pigs that snore though awake.
The delta-wing butterfly.
