What are the sleeping characteristics of bats, sea cucumbers and snails?

Bats hibernate in small groups and hang upside down on rocks or sticks.

Sea cucumbers sleep for four or five months in summer, and worms on the sea surface wake up when they return to the bottom of the sea in winter.

Snails sleep in winter, summer or drought, and wake up in warm and rainy weather.
