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:
“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 (1809–1845)
“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 (1889–1951)
“The atmosphere parents wish to create when talking with children about birth and reproduction is warm, honest, and reassuring, one that tells children they are free to ask questions as often as they need to, and you will answer them as lovingly as you know how.”
—Joanna Cole (20th century)
