@kathy79,
A paraphrase would be difficult. The
sound of the word 'crepuscular' (meaning 'at twighlight') can be said to evoke the sound of the sea at the shoreline 'where the night washes into the day'. And perhaps (
non) onomatopoeically , the word 'crepuscular' may also evoke a picture of 'a
silent creeping muscular' animal, thereby making the choice of the wotd even more apt.
