摘要: Some regions of the world have very limited variations in temperature during year. Adverse conditions such as lack appropriate food items and/or drying out shallow lakes may induce a state torpor. This is different from hibernation, which involves reduction temperature. Torpor characterized by cessation feeding, and eventually movement. In addition, tissue metabolism cardiac activity become downregulated, mainly reduced frequency. The torpor occurs some amphibians, reptiles lungfish, transition also increases CO2, accompanied O2 levels. African lungfish records surviving cocoon with up to 7 years without intake, but amphibians survive for several months.
