What is the top 10 animals?

It's impossible to create a definitive "top 10" list of animals because "best" is subjective and depends on what criteria you're using. Do you mean:

* Most intelligent? (e.g., chimpanzees, dolphins, elephants)

* Most beautiful? (e.g., peacocks, butterflies, hummingbirds)

* Most fascinating? (e.g., octopuses, jellyfish, sharks)

* Most important to the ecosystem? (e.g., bees, butterflies, earthworms)

* Most popular as pets? (e.g., dogs, cats, fish)

Please tell me what criteria you're using to define "top 10" so I can give you a more helpful answer!
