It is well known that within the tropics, the hybernation, or more properly aestivation, of animals is determined not by the temperature, but by the times of drought.
Most of the species' activity occurs in the water, but terrestrial environments are used for hibernation, aestivation, and nesting (Reese and Welsh 1997; Rathbun and others 2002).
However, representatives of the subclass Pulmonata (Cuvier, 1817), adapted to the sharp fluctuations of temperature, falling into the summer (aestivation period) or winter (hibernation period) lethargy.
Females can reproduce at most once every two years (Main 1987), probably due to the energetic requirements of reproduction and maternal aestivation during the summer months when males wander in search of females.
Aestivation refers to a period of decreased physiological activity in response to dry environmental conditions (Hayes et al., 2015).
Pest incidence, mortality, aestivation, feed intake and growth in West African giant snail (Achatina achatina) reared under different housing systems.
Temperatures above 28 [degrees]C are said to initiate aestivation, but the snail can survive temperatures near 45 [degrees]C (Raut & Ghose 1984).
Conversely, high water temperatures can also induce aestivation in some sea cucumber species, such as has been observed in Apostichopus japonicus and Australostichopus mollis (Yang et al., 2005).
This snail species seeks moist soil as an aestivation site to aid in maintaining body moisture because they do not feed while aestivating [14].
Skeletal muscle atrophy occurs slowly and selectively during prolonged aestivation in Cyclorana alboguttata (Gunther 1867).
In high- and low-humidity treatments, snails ceased movement after 48 h and appeared to enter a state of aestivation. Statistics were only calculated for the 28-day trial, due to the change in methods for the extended component of the study.
