可爱的鼻子的科学:冷和热

发布日期:2018-09-17 作者:admin

These infrared pictures show that some mammals keep their nose warm, while some keep them cold。 Can you guess which of the noses below belongs to each animal? Oh, and more importantly, can you guess why their noses are hot or cold? You’;ll find the answers at the bottom of this post。

The pictures come from scientists at Lund University in Sweden, and it’;s not just about curiosity or about taking nice pictures of cute schnozzes –; they are actually studying a specialized mammalian nose structure called the rhinarium。 The rhinarium is the moist, naked surface around the nostrils of the nose in most mammals。 In actual scientific usage it is typically called a “;wet snout”; or “;wet nose”; from its moist and shiny appearance。

“We want to know what mammals can do with specialized nose ***s,” Lund zoologist Ronald Kröger explains。

Many mammals, like dogs, cats or deer have wet, hairless rhinaria –; however, humans don’;t。 We like our noses dry。 The consequence of this is that the nerve interiors of different noses are also almost certainly very different。 Kröger and team is trying to find out what role do the rhinaria play in terms of temperature –; in other words, what advantages do mammals have from having hot or cold noses。

Previously, he researched animal vision, but interestingly enough, he got curious about rhinaria when his dog touched him with its cold nose, which made him wonder about its unusual temperature。

“I thought, this is so interesting, we have to know more,” he says。

So far, the team hasn’;t published any scientific *****s, but they’;re well on the way。
