Amphibious fish found to use evaporative cooling to overcome hot water

(Phys.org)—A team of researchers affiliated with the University of Guelph and Brock University, both in Canada, has found the first example of an amphibious fish using evaporative cooling to chill its overheated body. In their paper published in the journal Biology Letters, the researchers describe their study that included raising Kryptolebias marmoratus, aka mangrove rivulus, to adulthood and then testing them by heating the water in which they lived.
