Yeah I totally agree. It’s like grouping humans in with rhinos because we’re both mammals and have 4 limbs. Sharks are so ancient they diverged extremely early and are weird as fuck. I keep learning new and interesting ways sharks are almost alien compared to bony fish. Like how they use high urea content in their blood to lower the osmotic gradient dehydrating them (salt water sucks water out of your gills) so they turn ammonia into Urea to keep some dissolved compounds around to balance the osmotic pressure.
