Tale of Two Teeth answer

Written by Tursiops. Posted in Uncategorized

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.
