    Most of their leg is a finger look closely. Count the joints. The hand begins 3 joints up (one is hidden in the hoof so it’s not as obvious. Count down from the shoulder works too.) The wrist is 4 joints up, elbow 5, shoulder is the last one at 6 total. They have the same number of joints in the same spots that we do, just like a giraffe has the same number of neck bones as a rat.

    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.









  • Yeah they are but it seems like most electrical instructors don’t know that they just think “water is close enough as an analogy to electricity but breaks with AC” when in fact they’re both identical. So they’ll tell you to forget the water model while teaching you AC. The inertia/pipe strain comparison is very rare to hear.
