Gastrozooids

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.
The most visible polyps are the gastrozooids (responsible for feeding), the gonozooids (reproductive), and the tentacles, which are specialized and highly retractile polyps.
We established each pairing by excising a small piece of tissue carrying three to four gastrozooids from the sexually immature stock colonies of each contestant in a pairing, and then positioning these explants under monofilament threads approximately 5 mm apart on glass slides.
