If you sometimes wish you could sink back into the depths of the ocean, great news--the strange little guys who still live down there will receive you with open arms (and fins, claws, and tentacles). But if you're not quite ready to take to the sea, these friendly denizens of the deep offer solid advice for living on dry land, such as the following:

• "If you're happy and you know it, digest your brain."--The star tunicate, who avoids anxiety by digesting much of its own body
  
• "Never be afraid to set--and enforce--your boundaries."--The gloomy octopus, who protects its personal space by throwing dirt at anyone who bothers it
  
• "It's good to get it all out."--The fire-breathing shrimp, who vomits bioluminescent goo when threatened
  
• "If you love someone, absorb them into your bloodstream."--The fanfin anglerfish, who expresses love by fusing with its mate
  
• And more wonderfully wacky undersea weirdos who really know how to live!
