Macrodasys Caudatus
''Macrodasys caudatus'' is a species of microscopic worm-like metazoan in the family Macrodasyidae in the phylum Gastrotricha. It lives in the interstices between particles of sediment on the seabed in shallow water. It is found in the Indian Ocean, the northeastern Atlantic Ocean, the Mediterranean Sea and the North Sea. Morphology The body is worm-shaped with small adhesive tubes (spine-like structures) on the lateral sides. The head is not distinct. The pharyngeal pores are located in mid-pharyngeal region. Ecology ''Macrodasys caudatus'' is an aquatic, microscopic worm with a body length of . It can be found in marine waters. It is meiobenthic and lives between the sand grains and particles (interstitial) on the seabed. ''Macrodasys caudatus'' is acoelomate and swallows its food by powerful sucking action of the muscular pharynx. It is a detritivore and its diet consists of small protozoans, microalgae Microalgae or microphytes are microscopic algae invisible to the ...

Metazoan
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilateral symmetry, bilat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Macrodasyidae
Macrodasyidae is a family of worms belonging to the order Macrodasyida Macrodasyida is an order (biology), order of gastrotrichs. Members of this order are somewhat worm-like in form, and not more than 1 to 1.5 mm in length. Macrodasyids are almost in entirely marine and live in the sediment in marine or brack ....

Gastrotricha
The gastrotrichs (phylum Gastrotricha), common name, commonly referred to as hairybellies or hairybacks, are a group of microscopic (0.06-3.0 mm), worm-like, acoelomate animals, and are widely distributed and abundant in freshwater and Marine (ocean), marine environments. They are mostly Benthos, benthic and live within the periphyton, the layer of tiny organisms and detritus that is found on the seabed and the beds of other Body of water, water bodies. The majority live on and between particles of sediment or on other submerged surfaces, but a few species are terrestrial and live on land in the film of water surrounding grains of soil. Gastrotrichs are divided into two Order (biology), orders, the Macrodasyida which are marine (except for two species), and the Chaetonotida, some of which are marine and some freshwater. Nearly 800 species of gastrotrich have been described. Gastrotrichs have a simple body plan with a head region, with a brain and sensory organs, and a trunk w ...
