Grizzela
The Grizzelas were a species known to undergo hibernation cycles lasting at least six months.

In 2366, the Sheliak refused to allow the United Federation of Planets three weeks to remove 15,000 Human colonists from Tau Cygna V, which fell under Sheliak ownership as per the Treaty of Armens. Citing terms from the treaty, Captain Jean-Luc Picard named the Grizzelas as third party arbitrators to help settle the disputes. When Picard mentioned that the Grizzelas would not awaken for another six months, the Sheliak agreed to the original request of three weeks. ()
