Paramecia belong to the phylum Protozoa, which falls into the kingdom Protista. Paramecia are considered free-ranging protozoans that are generally very small in size. There are eight species of paramecium, which vary in appearance but share the characteristics of being single-celled organisms that are covered with tiny delicate hairs called cilia.Know More
Paramecia reside primarily in aquatic environments. Some live in oceans and seas, while others inhabit lakes, rivers and streams. These organisms are equipped with cilia for facilitating life in watery locations. Cilia essentially act as rudders to help propel organisms through the water. They also serve as integrated utensils and allow paramecium to obtain and ingest food particles.
Paramecia have oral grooves on their ventral surfaces, which run diagonally to their mouths and gullets. The gullets of paramecium are relatively large and aid digestion by transforming food particles into vacuoles, which are tiny storage sacs. Paramecia may have two or three contractile vacuoles, which expand to accommodate food and help to regulate water content within cells. Some vacuoles serve as excretory structures as well, by eliminating metabolic waste.
Paramecia have two nuclei, as do most protozoa. These nuclei contain genetic information that is stored and replicated to offspring upon reproduction. Macronuclei, the larger of the two nuclei, allows paramecia to survive, while micronuclei enable reproduction.Learn more about Zoology
The tiger's kingdom, phylum, class, order, family, genus and species, referred to as its taxonomy, is the kingdom animalia, the phylum chordata (which may also be called vertebrata), the class mammalia, the order carnivora, the family felidae, the genus panthera and the species p. tigris. Within the p. tigris species there are 10 sub-species.Full Answer >

All true fish belong to the phylum Chordata. Animals of this phylum possess a hollow backbone, and at various stages of development, all have grooves and slits in the area of the throat behind the mouth and a tail that extends past the anus.Full Answer >
Paramecia are unicellular. They are microorganisms that are classified under the protoctist phylum Ciliophora. They are cilliates that are characterized by long cilia that continuously beat to help the microorganisms move.Full Answer >
