Limenandra fusiformis is characterised by concentric rings forming 'targets'
down the dorsal midline. The rhinophore clubs have posterior papillae, there are
no papillae on cerata. When crawling the innermost cerata in the most posterior
row of each ceratal cluster waves around, that makes it appeare to 'jerk' along.
