Many animals sleep upside down.
Like for example ...
Bats, koalas, sloths, manatees (monkeys), goldfish (all sorts of fish), sea lions ( cetain- seals), leopards (in a certain way), snakes, (certain)
and all sorts such as bugs, insects, sea animals, and mammels. Who ever wrote the first answer needs to go back to sixth grade and learn what mammals are. Second manatees are not monkies. Goldfish are not mammals. Snakes are not mammals. Insects and bugs are not mammals. And mammals is not spelled with an e. As far as I know only one group of mammals routinely sleep upside down. At least on purpose. And those are bats, and their related species. Sorry to whoever wrote the first answer. I just couldn't let the glaring mistakes slide... Good luck with future answers.
