Tale of Two Teeth answer
Answer: Sperm whales are extremely sexually dimorphic – males grow much larger than females.
At 33.5’, a female sperm whale is near her full adult size, an old whale.
At 33.5’, a male sperm whale is a youngster, only approximately half his full size.
Therefore, the smaller tooth was from the male. The female had the larger tooth because she was much older. The photos below show the 2 whales from which the two teeth were taken.
