      Pull some out of your mouth and glue them to your forehead.

      Gotta work on improving yourself! Even if it doesn’t work, you’ll still feel better in the end.

    I did not read the article. I was curious why and how forehead tewth are an evolutionary advantage but I am okay with not knowing. That’s enough internet for next week

      Male sharks use teeth to hold female sharks during copulation, but ghost shark teeth are small and not suited for that purpose, so they evolved another set of teeth on their forehead to do the same job.

    Found only in males, the forehead rod—called a tenaculum—is the ghost sharks’ only source of distinct teeth, and it seems to be used to grasp females in much the same way sharks use their toothy mouths in mating.

    Tenaculum is the new word of the day!

    Ugh, I hate lazy science reporting like this. A title like « Horny fish seem to survive/breed more » is not only catchier but more accurate.
