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:
“As the twentieth century ends, commerce and culture are coming closer together. The distinction between life and art has been eroded by fifty years of enhanced communications, ever-improving reproduction technologies and increasing wealth.”
—Stephen Bayley (b. 1951)
“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)
“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 (1890–1976)
