What animal can be used to tell the temperature?

• Cricket:Crickets are cold-blooded and take on the temperature of their surroundings. In 1897, scientist Amos Dolbear published an article titled "The Cricket as a Thermometer" that noted the correlation between the ambient temperature and the rate at which a cricket chirps. The insects’ muscles contract to produce chirping, based on chemical reactions. Higher temperatures activate the cricket's muscles, increasing its chirps. Lower temperatures slow their reaction rate and reduce the frequency of the chirps. To convert cricket chirps to degrees Fahrenheit, count the number of chirps in 14 seconds and add 40.
