I would agree, but then I read the Wikipedia page which says that around 10 of these animals are caught every day as bycatch, so I assume the shark that was studied came from one of these.

This shark takes 150 years to reach sexual maturity and gestates for 8-18 years. It's pretty fucked up that bycatch at this rate is just accepted because it surely is going to lead the species to extinction. Humans are pretty fucking arrogant.

If these sharks were not caught at this rate then I would agree that they shouldn't be studied in ways that require killing them, but since they are, I think it is better to at least get some knowledge out of it and possibly raise awareness of the problem.

Edit: read the article, and it actually says it was caught by the scientists and not as bycatch. Still, this catch is negligible compared to the 3500 that are caught, killed and thrown out again (I assume) each year

is future possible cure for humans worth one shark eye?

how many fish, water mammals and may be humans shark killed for hundred years? did shark thought about their eyes?*

*except in sence that eyeballs are very delicios
