... copes with very challenging conditions that would harm or even kill lesser creatures. This is because the fish has evolved in small-to-medium sized ponds in a harsh continental-type climate in Asia where the winters are very cold and the summers are hot and steamy.

...rded submissive behaviors and also ensured that no harm came to either of the hamsters, which normally live alone. Because the smaller hamster was the intruder, the outcome of the dominance/submissive tussle was a foregone conclusion.
