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)
“What culture lacks is the taste for anonymous, innumerable germination. Culture is smitten with counting and measuring; it feels out of place and uncomfortable with the innumerable; its efforts tend, on the contrary, to limit the numbers in all domains; it tries to count on its fingers.”
—Jean Dubuffet (1901–1985)
