Some organisms are primarily independent and form facultative colonies in reply to environmental conditions while others must live in a colony to survive . For example, some carpenter bees will form colonies when a dominant hierarchy is formed between two or more nest foundresses [5] (facultative colony), while corals are animals that are ...
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) [6] are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about 0.5 millimetres ( 1 ⁄ 64 in) long, they have a special feeding structure called a lophophore , a "crown" of tentacles used for filter feeding .
In 2006, a huge clonal colony of the seagrass Posidonia oceanica was discovered south of the island of Ibiza. At 8 kilometres (5 mi) across, and estimated at 100,000 years old, [3] it may be one of the largest and oldest clonal colonies on Earth. [4] [5] [6] Among animals, the largest species are all marine mammals, specifically whales.
In other cases, certain animals were initially considered hoaxes – similar to the initial reception of mounted specimens of the duck-billed platypus (Ornithorhynchus anatinus) [1] in late 18th-century Europe. In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals.
Pyrosoma atlanticum, a tunicate, is a colony of zooids. A zooid or zoöid / ˈ z oʊ. ɔɪ d / is a single animal that is part of a colonial animal. This lifestyle has been adopted by animals from separate unrelated taxa. Zooids are multicellular; their structure is similar to that of other solitary
The functions and organizations of the zooids in colonies widely vary among the different species; however, the majority of colonies are bilaterally arranged with dorsal and ventral sides to the stem. [7] The stem is the vertical branch in the center of the colony to which the zooids attach. [7] Zooids typically have special functions, and thus ...
Diagram showing bacteria growing and forming into a biofilm on a surface. Colonisation or colonization is the spread and development of an organism in a new area or habitat. . Colonization comprises the physical arrival of a species in a new area, but also its successful establishment within the local communi
Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, [3] leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonies on the ground. Herons, egrets, storks, and other large waterfowl also nest communally in what are called heronries.
