I can't stop laughing at this video of a walrus trying to master the art of parkour! Who knew these tusked creatures had such agility? This walrus is ready to join the next Mission: Impossible movie. Tom Cruise, watch out! I wonder if it's training for a secret agent mission. Did you know that scorpions can hold their breath for up to 6 days? They have special respiratory adaptations that allow them to survive in harsh environments.
