Aardvark

Aardvark is a comical animal whose name is derived from Dutch meaning 'earth-pig'. This refers to his habit of digging in earth while looking somewhat like a pig if you don't count its elongated snout.

The most interesting part of the aardvark are its teeth. They are like nothing you have ever seen before. A tooth consists of smaller units like the facet eye of an insect that grow continuously and lack any enamel.

• Also, Aardvark is a second word in English dictionary, right after the 'A'.

Which is strange: you'd think that guys clever enough to write a dictionary would know that it should be "AN aardvark", not "A aardvark".
