Quotation from: The Gods of Mars

Written by: Edgar Rice Burroughs

As I had been scrutinizing this weird monstrosity the balance of
the herd had fed quite close to me and I now saw that while many
had the smaller specimens dangling from them, not all were thus
equipped, and I further noted that the little ones varied in size
from what appeared to be but tiny unopened buds an inch in diameter
through various stages of development to the full-fledged and
perfectly formed creature of ten to twelve inches in length.
