Thanks for the interesting and thought-provoking observation.

The slight issue here is that we are not comparing like with like. This comparison is of an instance of a thing (Alpha Umi Aa) with a category of things (sharks).

If I was to compare the category of sharks with the category of stars, I'd correctly observe that the category of stars are far older.

Equally, an individual shark doesn't hold a handle to an individual star like Alpha Umi Aa.
