Reproduction
The adults are found in pairs year round, perhaps suggesting a long-term monogamous bond. The pairs reproduce by rising up in the water, bringing their bellies close together, and release clouds of sperm and eggs. The female can release anywhere from 25 to 75 thousand eggs each evening and as many as ten million eggs during each spawning cycle. The eggs are transparent, buoyant, and pelagic, floating in the water column. They hatch after 15 to 20 hours into larvae that lack effective eyes, fins, or even a gut. The large yolk sac is absorbed after 48 hours, during which time the larvae develop normal characteristics of free swimming fish. Larvae are found in the water column and feed on plankton. The larvae grow rapidly and about 3–4 weeks after hatching the 15–20 millimetres (0.6–0.8 in) long juvenile settles on the bottom.

Famous quotes containing the word reproduction:
“Although Samuel had a depraved imagination—perhaps even because of this—love, for him, was less a matter of the senses than of the intellect. It was, above all, admiration and appetite for beauty; he considered reproduction a flaw of love, and pregnancy a form of insanity. He wrote on one occasion: “Angels are hermaphrodite and sterile.””
—Charles Baudelaire (1821–1867)
“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)
