Reproduction
Male Port Jackson sharks become sexually mature between ages 8 and 10, and females at 11 through 14. They are oviparous meaning that their eggs, which are laid annually, are produced in a group, rather than in live birth. Their breeding season begins in August, continuing until the middle of November while the female lays egg pairs off and on for every 10 to 14 days. As many as 8 pairs of offspring can be laid during this period. The eggs mature for 10–11 months before hatching at once from the sac. The babies, known as neonates, have an 89% mortality rate of dying before even being born.

Famous quotes containing the word reproduction:
“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)
“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)
