Pseudocoelomate is the word used for an animal with an unlined body cavity made up of a tube surrounded by organs. A roundworm is one example of a pseudocoelomate.
A Planarian is an acoelomate, meaning they do not have a body cavity at all.
The rotifers make up a phylum of microscopic and near-microscopic pseudocoelomate animals. They were first described by Rev. John Harris in 1696, and other forms were described by Anton van Leeuwenhoek in 1703.
The class of animals that contains the least examples is the family, as it is the lowest level in the classification of animals.
Elephants are animals which have molars
rotifers are microscopic aquatic animals. They are commonly found in mosses and lichens. Examples are Philodina and collotheca.
examples of heterotrouphs are:- animals and humans.
Animals are classified according to body plan as symmetrical or asymmetrical. Symmetrical animals are usually bilateral (two-sided) or radial (multiple planes of symmetry), while asymmetrical animals have no defined body plan. These classifications help scientists understand the evolutionary relationships between different groups of animals.
