A microbial colony is defined as a visible cluster of microorganisms growing on the surface of or within a solid medium, presumably cultured from a single cell. [11] Because the colony is clonal , with all organisms in it descending from a single ancestor (assuming no contamination ), they are genetically identical, except for any mutations ...
Siphonophorae (from Greek siphōn 'tube' + pherein 'to bear' [2]) is an order within Hydrozoa, which is a class of marine organisms within the phylum Cnidaria.According to the World Register of Marine Species, the order contains 175 species described thus far.
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 animals.
An ant colony is a population of ants, typically from a single species, capable of maintaining their complete lifecycle. Ant colonies are eusocial , communal, and efficiently organized and are very much like those found in other social Hymenoptera , though the various groups of these developed sociality independently through convergent ...
The colony is bumpy on the outside, each bump representing a single zooid, but nearly smooth, although perforated with holes for each zooid, on the inside. [ 5 ] [ 8 ] Pyrosomes are planktonic , which means their movements are largely controlled by currents, tides, and waves in the oceans.
New zooids are added by budding as the colony grows. Long tentacles hang below the float as the animal drifts, fishing for prey to sting and drag up to its digestive zooids. [35] [36] The colony hunts and feeds through the cooperation of two types of zooids: tentacle-bearing zooids known as dactylozooids (or palpons), and gastrozooids. [10]

Single animals, called zooids, live throughout the colony and are not fully independent. These individuals can have unique and diverse functions. All colonies have "autozooids", which are responsible for feeding, excretion, and supplying nutrients to the colony through diverse channels. Some classes have specialist zooids like hatcheries for ...
