Today’s interesting fact has to do with the platypus, often referred to as the duckbilled platypus.

This is one of the five species of Monotremes that are still with us.

A Monotreme is an egg laying mammal that nurses its young.

Unlike placental or marsupial mammals which have two sex chromosomes, one pair; the platypus has ten sex chromosomes, five pairs.

There is no agreed plural of the word platypus.

Platypuses is sometimes used as is platypi but the first is by English rules and the second is pseudo-Latin.

The name platypus is derived from Greek, so the correct plural is really platypodes.
