What manner o' thing is your crocodile?

It is shaped, sir, like itself; and it is as broad as it hath breadth: it is just so high as it is, and moves with its own organs: it lives by that which nourisheth it; and the elements once out of it, it transmigrates.

What colour is it of?

Of it own colour too.

'Tis a strange serpent.

'Tis so. And the tears of it are wet.
