Physical Appearance
Rather than having true scales, the Atlantic sturgeon has five rows of bony plates known as scutes. Specimens weighing over eight hundred pounds and nearly fifteen feet in length have been recorded, but they typically grow to be six to eight feet (1.8–2.4 m) and no more than three hundred pounds (140 kg). Its coloration ranges from bluish-black and olive green on its back to white on its underside. It has a longer snout than other sturgeons and has four barbels at the side of its mouth.

“For my part I do, qua lay physicist, believe in physical objects and not in Homer’s gods; and I consider it a scientific error to believe otherwise.”

“Never before has a generation of parents faced such awesome competition with the mass media for their children’s attention. While parents tout the virtues of premarital virginity, drug-free living, nonviolent resolution of social conflict, or character over physical appearance, their values are daily challenged by television soaps, rock music lyrics, tabloid headlines, and movie scenes extolling the importance of physical appearance and conformity.”
—Marianne E. Neifert (20th century)
