Colony (biology)
In biology, a colony (from Latin colonia) means several individual organisms of the same species living closely together, usually for mutual benefit, such as stronger defences, the ability to attack bigger prey etc.

Colony filters are plated at a density of 6 x 6 x 384, or 13,824 colonies per 8 x 12 cm filter. All colonies are plated in duplicate in a unique offset pattern optimized to prevent ambiguity in identification of positive offsets.

Colonial invertebrates like sponges and corals don't show signs of aging. Even individual cnidarians, like the sea anemone that lived for 78 years, show little or no sign of aging.

colonial -- Condition in which many unicellular organisms live together in a somewhat coordinated group. Unlike true multicellular organisms, the individual cells retain their separate identities, and usually, their own membranes and cell walls.

Colony. A group of identical cells (clones) derived from a single progenitor cell. Commensalism. The close association of two or more dissimilar organisms where the association is advantageous to one and doesn't affect the other(s).

[They] start off with a bunch of micro colonies on the surface. One here and one some distance away, and they grow up in either mushrooms or towers and some more come up. They leave a space in between themselves.

This "sampling error" leads to the founder effect: rapid changes in allele frequencies in the colonizing population and divergence from the parent population.

Screening by hybridization involves spreading the mixture of bacteria out on a dozen or so agar plates to grow several ten thousand isolated colonies.

Suppose that a pet store owner observes that the mice in her colony grow slowly. She hypothesizes that they grow slowly because she does not give them enough food. To test this hypothesis, she uses two groups of mice.

Thomas Hunt Morgan crossed a sport white-eyed male fruit fly with red-eyed females from the same colony.
F1 progeny, all with red eyes, were sib-mated.
The types of F2 flies recovered are shown at left. Note the absence of white-eyed females.
