Why do Arctic living things tend to be compact?

Expert Answers

To find the answer to this, all you have to do is look in the book.  It's in the first chapter, page 8 in my copy.  This is where Miyax's physical appearance is being described to us.

The author says that this is because of how cold it is in the Arctic.  She says that long, slender things do not do well in the Arctic because they have a lot of surface area on their bodies.  Heat dissipates more quickly from a body that has a lot of surface area in proportion to its mass.  So something that is compact will have less surface area and will not lose its heat so fast.  This is important in a cold climate.
