Contrary to common wisdom, scientist discovers some mammals can smell objects under water

bility was limited to the star-nosed mole or if other small semi-aquatic mammals also have it, Catania captured some water shrews and began testing them. He found that they also exhibit this underwater sniffing behavior and can use it to follow underwater scent trails.

"Now, the question is, 'What other semi-aquatic mammals do this"'" Catania said. "Do animals like otters and seals do anything similar" Or is there a size limit and it only works for smaller mammals""

He hopes that publication of his paper will encourage researchers who are studying all kinds of semi-aquatic animals to take a closer look at how they are using their noses underwater.
