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:
“Perhaps life is just that ... a dream and a fear.”
—Joseph Conrad (1857–1924)
“If Mr. Vincent Price were to be co-starred with Miss Bette Davis in a story by Mr. Edgar Allan Poe directed by Mr. Roger Corman, it could not fully express the pent-up violence and depravity of a single day in the life of the average family.”
—Quentin Crisp (b. 1908)
“The authoritarian child-rearing style so often found in working-class families stems in part from the fact that parents see around them so many young people whose lives are touched by the pain and delinquency that so often accompanies a life of poverty. Therefore, these parents live in fear for their children’s future—fear that they’ll lose control, that the children will wind up on the streets or, worse yet, in jail.”
—Lillian Breslow Rubin (20th century)
