Hydrozoan colony.
The “breadbasket colonies” were the North American colonies that produced more food than the other colonies in the country. These colonies were comprised of small farms that grew wheat, apples, peaches and other foods.
The colonial hydrozoan, Hydractinia symbiolongicarpus, is an ideal system to study the functional distribution of nematocyst types and their venoms, given that they display a division of labor through functionally distinct polyps within the colony.

Description. Hydroids or Hydrozoan jellyfish are related to the “true” jellyfish (Scyphozoa), and like the latter they use stinging cells called nematocysts to catch their prey; venomous harpoons that shoot out when a prey encounters them. Most Hydrozoa live most of their lives as a colony of polyps on the seabed. The Portuguese man o’ war is a carnivore. The majority of its diet (70 to 90%) is made up of small fish, although the colony occasionally captures larger prey. The Portuguese man o’ war also feeds on plankton such as shrimp and other small crustaceans. The colony’s prey is captured by the long, ribbon-like dactylozooids.Class Hydrozoa A.Body plan B.Colony Growth C.Life History Polyps are small and may occur as solitary or colonial Colony Growth Forms Colonies grow in one of 3 main patterns Hydrorhizal Monopodial Sympodial Medusae are small and not as structurally complex as the scyphozoan medusae Characteristics of Class Hydrozoa dimensional shaping of hydrozoan colonies. This is underscored by the findings of Mayorova et al. (2015) that reported the shoot tip of the colony has organizing properties in that when transplanted, it can initiate a new axis. Depending on the species, benthic hydrozoan colonies can be either stolonal and encrust the substrate, or grow upright.(a), Adhering to hydrozoan colony Dentitheca dendritica under Blue Heron Bridge, Riviera Beach, Florida, 7 m depth, 28 July 2020 (b), six individuals from the same hydrozoan in various stages of fissiparity. Note salmon-pink patches on all individuals.6.TYPES OF POLYMORPHISM A few coelenterates, such as Hydra and sea anemone are monomorphic in which only polyp stage is found but other coelenterates exhibit polymorphism. Dimorphism: Many hydrozoan colonies like Tubularia and Campanularia have only two types of zooids, the feeding zooids or gastrozooids and medusae or nectophores that …
