Gastrozooids

 

zooids in colonies of Coelenterates (hydropolyps, hydrocorals, and Siphonophores) that carry out the digestive function. They resemble polyps with partially or completely atrophied tentacles. Located nearby or at the base of the gastrozooid are zooids adapted for capturing prey (dactylozooids, stinging tentacles) and which transfer their prey to the gastrozooid for digestion.

In the laboratory, small pieces of tissue, or explants, including four or five gastrozooids were excised with a scalpel and transferred with watchmaker's forceps to plain glass microscope slides (7.64 cm X 3.82 cm, 1.1-1.3 mm thick).
The most visible polyps are the gastrozooids (responsible for feeding), the gonozooids (reproductive), and the tentacles, which are specialized and highly retractile polyps.
This colony consists of a central polyp specialized in feeding (the gastrozooid), above which there is a circular floater.
At the same time, we also established clonal explants of the parental colonies by excising with a scalpel a small section of ectodermal mat containing several feeding polyps (gastrozooids) from the stock colonies on the hermit crab shells (Ivker 1972).
