Atlantic Wolffish - Reproduction

Reproduction

The manner of which Atlantic wolffish fertilize their eggs distinguishes them from many fish. Instead of the female depositing her eggs in the open ocean for the male fish to fertilize and then continue on his way, they are internally fertilized and the male wolffish stays with the nest and protects the eggs for as long as four months, until the brood is strong enough to gain independence. Their eggs are 5.5–6.0 mm in diameter, (among the largest fish eggs known), yellow tinted and opaque. The eggs are laid on the ocean floor, many times in shoal water, sticking together in loose clumps, surrounded by seaweed and stones. Atlantic wolffish mature relatively late, at age six.

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)

    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)

    The chief function of the city is to convert power into form, energy into culture, dead matter into the living symbols of art, biological reproduction into social creativity.
    Lewis Mumford (1895–1990)
