dactylozooid
A dactylozooid is a specialized defensive or feeding polyp in colonial marine invertebrates like siphonophores and hydroids.
Unlike reproductive polyps, dactylozooids are modified for capturing prey or protecting the colony, typically bearing stinging cells.
They lack mouths and depend on other colony members for nutrition.
