| Abstract |
Tintinnids are shell building Protozoa regarded as heterotrich ciliates. Most of them are marine; less than 2% of the 800 known species occur in fresh water. Tintinnids live almost exclusively free-swimming pelagic and occur at all latitudes, in all seas, predominantly in the upper illuminated water layers. Their geographical distribution is primarily controlled by temperature and so is their development; salinity and oxygen seem of little importance. Tintinnids are one of the first links in the food chain. They feed on detritus, bacteria, naked flagellates, coccolithophores, peridineans and diatoms. The tintinnids themselves are eaten by copepods, euphausiids, tunicates and fish larvae. |
