# Shark Tooth - Counting

Counting

In taxonomy, shark teeth are counted as follows: rows of teeth are counted along the line of the jaw, while series of teeth are counted from the front of the jaw inward. A single tooth row includes one or more functional teeth at the front of the jaw, and multiple replacement teeth behind this. For example, the jaws of a bull shark can have 50 rows of teeth in 7 series, with the outermost series functional. The small teeth at the symphysis, where the two halves of the jaw meet, are usually counted separately from the main teeth on either side.

### Famous quotes containing the word counting:

If all power is in the people, if there is no higher law than their will, and if by counting their votes, their will may be ascertained—then the people may entrust all their power to anyone, and the power of the pretender and the usurper is then legitimate. It is not to be challenged since it came originally from the sovereign people.
Walter Lippmann (1889–1974)

If you’re counting my eyebrows, I can help you. There are two.
Billy Wilder (b. 1906)

Is it not manifest that our academic institutions should have a wider scope; that they should not be timid and keep the ruts of the last generation, but that wise men thinking for themselves and heartily seeking the good of mankind, and counting the cost of innovation, should dare to arouse the young to a just and heroic life; that the moral nature should be addressed in the school-room, and children should be treated as the high-born candidates of truth and virtue?
Ralph Waldo Emerson (1803–1882)
