Can you tell the age of a whale by the size of its blowhole?

No, it is not possible to tell the age of a whale by the size of its blowhole. The size of the blowhole has nothing to do with the age of the whale. The blowhole is the nasal opening on top of the head of a whale, and it is used for breathing. The size of the blowhole varies depending on the species of whale, but it does not change with age. There are other ways to determine the age of a whale, such as counting the rings on their ear wax, looking at their teeth, or using genetic analysis.

No, you cannot tell the age of a whale by the size of its blowhole. The size of a whale's blowhole is determined by its species and size, not its age. For example, a blue whale has a larger blowhole than a humpback whale, even though the humpback whale is typically older.

The best way to determine the age of a whale is to take a biopsy of its earplug. The earplug is a waxy material that forms in the whale's ear canal over time. Each year, the whale adds a new layer of material to its earplug. By counting the layers of material, scientists can determine the whale's age.

Another way to determine the age of a whale is to use a technique called photo-identification. This involves taking photographs of whales and then comparing them to photographs of whales that have been previously identified. By tracking the changes in a whale's appearance over time, scientists can determine its age.
