Did you know?
WebSome animals present freeze-tolerance, which allows them to survive ice formation in their bodies. This is quite typical in many invertebrates (insects, gastropods, nematodes). Other animals (like marine fish) directly avoid freezing: they are freeze- intolerant. They possess antifreeze compounds. WebFreeze tolerance is a complex cold-hardiness adaptation that has independently evolved in a diverse group of organisms, including several ectothermic vertebrates. Because little …

The second stage occurs at lower temperatures as intercellular ice continues to form.
WebFreezing occurred at higher subzero temperatures on wet substrate than on dry substrate in all species, indicating susceptibility to inoculative freezing. P. triseriata was freeze-tolerant, but survival was dependent on the level of supercooling prior to freezing. All Bufo were freezing intolerant, regardless of crystallization temperature.
