Sorry Juan, i was unaware that octopods are members of the mammilia family, or for that matter, Kiwi or all the other animals that have come up

the answer, of course, is the last mammal that became extinque.

smart animals adapt to new challenges, dumb animals get done in. wooly mommouths were big, (and could feed the village for weeks) and had tough skin, and tusks, but they were not smart enough to outwit men armed with wooden sticks and stone spear tips. and so they are no more...

i think there are other marine animals that have copper based blood, not just horseshoe crabs and octopods.
