With an incredible diversity of animals surveyed, we have identified many top contenders from all categories. Now it's time to evaluate them against the criteria to decide the world's best.

Evaluating the Candidates Against the Criteria

Based on the criteria defined earlier for intelligence, physical capabilities, usefulness to humans, and more, we can start to narrow down the animal options:


  • Elephants excel in empathy and cognition but lack useful direct human applications.
  • Orca intelligence meets apex predatory dominance as an impressive marine hunter.
  • No other animal serves humans like dogs across so many roles.
  • Big cats have iconic status but lack domestic applications.


  • Parrots have talking skills unmatched in the animal world.
  • Eagles soar skillfully but offer limited tangible human use.
  • Owls lean heavily on exceptional hearing over other criteria.

Reptiles and Amphibians

  • Chameleons blend in remarkably but lack application as exotic pets only.
  • Ancient sea turtles play key ecosystem roles but don't exhibit the highest intelligence.
  • Poison dart frogs offer few advantages beyond their toxicity.


  • Octopuses show high intellect for invertebrates but still lag mammals in smarts.
  • Ants form amazingly complex colonies but rank low on an individual basis.
  • Bees pollinate plant life through instinct rather than active intellect.

Marine Mammals

  • Dolphins demonstrate high intelligence tempered by a lack of human usefulness.
  • Whales have communication and songs but minimal tangible human benefit.

Unusual Species

  • Tardigrades: Survival experts, but with limited mobility, usefulness, or cognition.
  • Naked mole rats: Extreme adaptation to a specific niche below ground.
  • Aye-ayes: Cool and bizarre but not outstanding based on global criteria.

And the winner is...

Announcing the Best Animal in the World

Based on a balanced assessment across all categories, the best animal in the world is....

The Dog!

Dogs edge out other highly intelligent mammals due to the unique symbiotic partnership they have evolved with humans over millennia. Attributes like:

  • Companionship, joy, and unconditional love for owners.
  • Vital working roles herding livestock, aiding police and military, assisting the blind, and more.
  • Sensory capabilities like supreme scent tracking skills that aid humans.
  • Understanding of gestures, commands, and human social cues.
  • Broad diversity of over 300 dog breeds selectively optimized for various tasks.
  • Globally popular in roles from family pet to TV star.

...mean dogs excel across intelligence, usefulness to humans, adaptability, and iconic status. Other animals like elephants and dolphins may match dogs in some categories but lack the direct human applicability.

In the end, the dog's unique history bonding with humans tips them as the world's best animal overall. Their loyalty, devotion, and varied services to mankind set them above even the most majestic or intelligent wildlife.

For millennia, dogs proved themselves as man's best friend. Now, they can rightly claim the title of best animal in the world!
