Yes, the remora fish uses its sucker on top of its head to attach itself to the bottom of the shark thereby the shark is protecting the remora from predators.
Penguins are maladapted to predation on land, although they are highly adapted in the water. This isn't a problem however, as they are only predated when in the sea. Their main predators are seals and Orcas. The penguins are very fast underwater with fast turning capabilities which enables them to sometimes out run their predators. Most penguins will swim for the ice when predators appear. They propel themselves upwards, leaving a stream of bubbles behind them which enables them to propel themselves up to 3m above the water when jumping onto the ice, this prevents predators reaching them from the water.
They were fast, like ostriches today, and the biggest and most powerful of all birds, so it probably had few natural predators. It was no match for humans, of course.
