Nestled across from Rockefeller Center lies Manhattanâs premier department store, Saks Fifth Avenue. Spanning an entire city block, the shopping center is as glamourous at it was when it opened, nearly 100 years ago.
Rotifers are small, mostly freshwater animals, and are amongst the smallest members of the Metazoa -- that group of multicellular animals which includes humans, and whose bodies are organized into systems of organs.delloid rotifers are the commonest variety found in fresh water. The term describes their habit of moving about by extending the body and attatching the head, then catching up with the foot and again extending the body -- bdelloid, like a leech.
Protists were traditionally subdivided into several groups based on similarities to the higher kingdoms: the unicellular animal-like protozoa, the plant-like protophyta (mostly unicellular algae), and the fungus-like slime molds and water molds.rotists live in almost any environment that contains liquid water. Many protists, such as algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton.
