"Siphonobranchiata" Natural Recordings by Native Speakers
The word "siphonobranchiata" refers to a class of colonial, coenenchymate ciliates, a type of soft-bodied aquatic animal. This class is part of the phylum Ciliophora. The name is derived from the Greek words "sipho" or "sphia" (funnel), "bros" (arm), and "branchia" (gill), relating to the funnel-shaped symmetry of their ciliature and colonial organization.
Siphonaria is a genus of air-breathing sea snails, marine gastropod mollusks in the family Siphonariidae. They are also known as puppy dog's tooth shell.
