by the way, fellow mammals: kangaroos and opossums have the same plumbing.. i.e., they too, have cochleas

They do have cochleas (all mammals do). But birds don't.

Since kangaroos, opossums, and birds all have cochleas, this is technically correct. The best kind of correct.

We talking about marsupial kangaroos or mammal kangaroos?

FYI, and as I am sure you know, mammals that have the dual plumbing ports (for liquid and solids... #1 and #2 respectively LOL) are called placental mammals.

And marsupial is the other referenced my my post along with odd monotremes which are how duck billed platypuses are categorized.

Interesting. I always thought that mammals and marsupials were different because of the lack of mammaries.
