In lakes and pools that appear physically cut off from other bodies of water, fish sometimes seem to materialize out of nowhere. This somewhat mystical sounding theory might not be far off: a new study suggests fish eggs may simply fall from the sky. In experiments, some fish eggs hatched after being pooped out by ducks, suggesting that feathered flight could facilitate seemingly immaculate piscine invasions, reports Priyanka Runwal for Audubon.
