| souixan said: Did you know the platypus together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth to live young. It is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), |
Did you also know that the duck-billed platypus's sperm is poisonous.
And that a fruit fly's sperm is a few CMs long, but I can't remember how many, I think it may have been 4, or 5.
