Antifreeze agents in the body fluid of winter active insects and spiders

Article

Summary

Insects and spiders which are active at subzero temperatures on snow in winter are found to be protected against internal freezing by antifreeze agents present in their body fluid. The body fluid has a melting point of about −1 °C, but the antifreeze agents prevent growth of ice crystals at temperatures down to −6 to −7 °C.
