Reproduction
During late summer, the females lay their eggs. Each egg is within a leathery black eggcase known by the common name "mermaid's purse" (as are the eggcases of other rays, skates and sharks.) These "purses" often wash up on beaches after rough weather, although usually they wash up empty, the young ray having already hatched out.

Famous quotes containing the word reproduction:
“An original is a creation
motivated by desire.
Any reproduction of an original
is motivated by necessity ...
It is marvelous that we are
the only species that creates
gratuitous forms.
To create is divine, to reproduce
is human.”
—Man Ray (18901976)
“Were I called on to define, very briefly, the term Art, I should call it the reproduction of what the Senses perceive in Nature through the veil of the soul. The mere imitation, however accurate, of what is in Nature, entitles no man to the sacred name of Artist.”
—Edgar Allan Poe (18091845)
“It is so characteristic, that just when the mechanics of reproduction are so vastly improved, there are fewer and fewer people who know how the music should be played.”
—Ludwig Wittgenstein (18891951)
