Life
The expedition conducted in 1960 observed (with great surprise because of the high pressure) at the bottom large living creatures such as a sole or flounder about 30 cm (1 ft) long, and a shrimp. According to Piccard, "The bottom appeared light and clear, a waste of firm diatomaceous ooze". Many marine biologists are now sceptical of the supposed sighting of the flatfish, and it is suggested that the creature may instead have been a sea cucumber.
During the second expedition, the unmanned vehicle KaikÅ collected mud samples from the seabed. Tiny organisms were found to be living in those samples.
In July 2011 a research expedition deployed untethered landers, called dropcams, equipped with digital video and lights to explore this region of the deep sea. Amongst many other living organisms, some gigantic single-celled amoebas with a size of more than 4 inches (10 centimeters), belonging to the class of xenophyophores were observed. Xenophyophores are noteworthy for their size, their extreme abundance on the seafloor and their role as hosts for a variety of organisms.

Famous quotes containing the word life:
“San Francisco is where gay fantasies come true, and the problem the city presents is whether, after all, we wanted these particular dreams to be fulfilled—or would we have preferred others? Did we know what price these dreams would exact? Did we anticipate the ways in which, vivid and continuous, they would unsuit us for the business of daily life? Or should our notion of daily life itself be transformed?”
—Edmund White (b. 1940)
“I remember my youth and the feeling that will never come back any more—the feeling that I could last for ever, outlast the sea, the earth, and all men; the deceitful feeling that lures us on to joys, to perils, to love, to vain effort—to death; the triumphant conviction of strength, the heat of life in the handful of dust, the glow in the heart that with every year grows dim, grows cold, grows small, and expires—and expires, too soon, too soon—before life itself.”
—Joseph Conrad (1857–1924)
“He ... was a sociologist; he had got into an intellectual muddle early on in life and never managed to get out.”
—Iris Murdoch (b. 1919)
