They can protect themselves but not against whales. They protect themselves by traveling in large numbers.
Llamas protect themselves by running away. They also spit when irritated or guarding a baby.

They protect themselves by squirting ink.
Citizens protect themselves with police departments. Nations protect themselves with a military.

People can protect themselves by moving to higher grounds
They protect themselves my balling up into a tight, small ball, then raise their quills up to protect themselves at all sides of their otherwise, furry bodies. ^^
