who is the smallest animal in the world

ant

micro-organisms

hummingbirds

mm

Wikianswers say strictly speaking Amoebasare the smallest animal, wierd eh?

KIESH2

what is that ?

This hasn't anything to do with chess so it should be posted under the Off Topic section.

Nonetheless, I actually think the world's smallest animal would be a nematode. They can be found at the bottom of an ocean.

Here's a picture of a Gastrotricha:

The 6 kingdoms of life:  Archae, Eubacteria, Protista, Fungi, Animalia, & Plantae

• Amoebas - belong to kingdom Protista, not Animalia. They're not animals.

• micro-organisms - Bacteria belong to kingdoms Archae & Eubacteria. Virii do not belong to any kingdom--Scientists still debate whether they're alive.
  

Nematodes seems like the best guess so far. Beatle nematodes are 285-340 micrometers long-that's pretty darn small! And they actually are animals.

[Note: This thread probably belongs in off-topic.]

likeforests,

your posts are usually pretty accurate and I'm out of my depth here, but....

"The 5 kingdoms of life are: Animalia, Plantae, Fungi, Protista, Archaea, Bacteria."

....isn't that 6?

Hah! You got me. I just double-checked the names:

     Archaebacteria, Eubacteria, Protista, Fungi, Animalia, and Plantae

google gives this

sstteevveenn - Most sites seem to classify Amoeba as Protista not Animalia. I'm no biologist so I have to defer to other resources on what is an animal.

See:

• http://biology.about.com/od/evolution/a/aa091004a.htm
• http://www.gov.ns.ca/natr/wildlife/wns/WNS6.HTM

Just to let you know, they now recognize 6 kingdoms: Archaebacteria (also called Archea), Eubacteria, Protista, Fungi, Animalia, and Plantae). The rest is correct.

Shoot me now

Everyone I am learning about the 5 (or 6) kingdoms of life in Biology so i know what i am talking about :)

The 5 kingdoms are:

Animalia (animal kingdom)

Plantae (plant kingdom)

Fungi

Monera (aka bacteria)

Protoctista (other)

There is a 6 kingdom system but they do not use it quite yet. They might in the future though.

who care if this was suppose to be in the off topic, is "fun" isn't ?

No animal is who.

chess is a animal...well we got the knight that look like a horse and is pretty small !

Shoot me faster

exactly, as if google cant answer such questions, the smallest micro organism is in my pants...or wait a minute i didnt mean that...
