Microfauna (from Ancient Greek mikros 'small' and from Latin fauna 'animal') are microscopic animals and organisms that exhibit animal-like qualities and have body sizes that are usually <0.1mm. [1] [2] Microfauna are represented in the animal kingdom (e.g. nematodes, small arthropods) and the protist kingdom (i.e. protozoans). A large amount ...

[33] [34] The name water bear comes from the way they walk, reminiscent of a bear's gait. The name Tardigradum means 'slow walker' and was given by Lazzaro Spallanzani in 1776. [ 35 ] [ 10 ] In 1834, C.A.S. Schulze gave the first formal description of a tardigrade, Macrobiotus hufelandi , in a work subtitled "a new animal from the crustacean ...
Animalcule (Latin for 'little animal'; from animal and -culum) is an archaic term for microscopic organisms that included bacteria, protozoans, and very small animals. The word was invented by 17th-century Dutch scientist Antonie van Leeuwenhoek to refer to the microorganisms he observed in rainwater. Some better-known types of animalcule include:
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
Animal – multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Subkingdom Parazoa. Porifera; Placozoa; Subkingdom Eumetazoa ...
Most zooplankton are microscopic but some (such as jellyfish) are macroscopic, meaning they can be seen with the naked eye. [1] Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, foraminiferans, radiolarians, some dinoflagellates and marine microanimals.
Such organisms can be single-celled [1] or multicellular. Microorganisms are diverse and include all bacteria and archaea, most protists including algae, protozoa and fungal-like protists, as well as certain microscopic animals such as rotifers. Many macroscopic animals and plants have microscopic juvenile stages.
