The Platypus is stranger than you think.

Platypuses have no nipples.  After the young hatch, the mother oozes milk from the pores all over her body.

The male platypus has a poison barb on the inside of its hind legs.  The purpose of this weapon is uncertain.

While often compared to the beaver, the platypus is only about 20 inches in length -- more comparable to the size of the muskrat.

The Platypus bill is actually just an elongated muzzle covered with much the same kind of tough skin found on a dog's nose.  This bill contains an electrically-sensitive organ that can detect the electrical signatures of the small aquatic animals it eats.

The biggest lift vehicle since the Saturn!

How does the fuel to orbit ratio work on rockets of this size? Why are they able to get cargo to space so much cheaper than smaller rockets?

It depends on the fuel density and how much structual weight and support is required.  With larger rockets, the mass ratio decreases and you accually get a bigger return for the amount of thrust needed to lift the payload into LEO
