WHEN RABBITS GET HOT, HOW DO THEY COOL OFF?
The answer is they release the heat through their ears. Healthy rabbit's ears are warm to the touch. Sick rabbits might have cold ears. Although when rabbits have been resting, their ears tend to get cooler, but once they wake up and move around their ears should be warm to the touch. So rabbits cannot pant like dogs or sweat like people and they don't sleep to cool off. When your rabbit is very hot, misting its ears with cool water will help it to cool down.
WHICH TYPE OF WATER DO HERMIT CRABS NEED DAILY?
The answer is both. Hermit crabs need dechlorinated freshwater to drink and they need saltwater to bathe in. (although sometimes they will also drink the saltwater). Each type of water should be in a fairly deep dish so that the crab can almost all the way submerge itself, but there needs to be some way for the hermit crab to climb out to avoid drowning. Making sure they have plenty of each kind of water is important. Obviously if they can't drink water they will die, but if they don't soak themselves in saltwater enough they won't be able to maintain the right levels of salinity inside their shells, and if they don't stay moist enough the crab will actually dry out and die.
Just for clarification, the water is not for the crabs to live in, they are not aquatic like fish or red clawed crabs. Pet hermit crabs are most often land crabs, so they will drown in water (which is why there needs to be a way out of the bowls) but they do need to soak in water frequently and have a humid environment so that they don't dry out.
