Which animal is called the lord of creation?

The many-pocketed animal is said to be the "lord of creation".

To his horror he recollected that he had left both coat and waistcoat behind him in his cell, and with them his pocket-book, money, keys, watch, matches, pencil-case—all that makes life worth living, all that distinguishes the many-pocketed animal, the lord of creation, from the inferior one-pocketed or no-pocketed productions that hop or trip about permissively, unequipped for the real contest.
