hibernation's summer cousin — sleeping through the heat instead of the cold.
means a period of dormancy some animals enter during hot, dry conditions to conserve water and survive the season.
from from latin aestivare, to spend the summer, itself from aestas, meaning summer — coined as the logical counterpart to hibernation once biologists noticed dry-season sleepers.
