Yep, fish can drown!! The reason being that when a fish is out of water, the water molecules on the fish's gills stick together, causing the gills themselves to stick together and oxygen cannot pass through gills, so technically they drown.
Also Bears don't actually hibernate (not a TRUE hibernation anyway). Hibernation is a specific term used to refer to a long-term torpor in cold weather. What the heck is torpor you ask? Well it's basically a natural hypothermia where an animal is able to significantly lower their metabolic rate and their ability to respond to stimuli. The reason why bears don't actually hibernate is that they only reduce their metabolic rate slightly (for an animal of their size to wake up from a proper hibernation would require them to consume more energy than that required to remain at a normal metabolic rate for the period, and would take more than a day). But they neither do they eat or drink, or pass urine or faeces - it's more of a case of them enduring a long period of starvation than an actual hibernation. Females can even give birth and nurse cubs during this period.
And lastly, some arctic fish and crustaceans have a chemical in their blood which acts as an anti-freeze, so that the animal can appear frozen, but once the ice clears they become active again.
