They are bilaterally symmetrical (i.e., the right and left sides are similar) Most of the speciesand the best-knownare those in the subclass Eucestoda; they are ribbon-like worms as adults, known as tapeworms.Their bodies consist of many similar units known as proglottidsessentially packages of eggs which are regularly shed into the environment to The three Cipxovms who appear in the loth-century inscriptions just mentioned bear alternately the names Torcotorius and Salusius; and, inasmuch as this is the case with the judices of Cagliari from the 11th to the 13th century, there seems no doubt that they were the successors of these Byzantine ripXovrfs, who were perhaps the actual founders of the dynasty. Platyhelminthes are bilaterally symmetrical animals: their left and right sides are mirror images of each other; this also implies they have distinct top and bottom surfaces and distinct head and tail ends.Like other bilaterians, they have three main cell layers (endoderm, mesoderm, and ectoderm), while the radially symmetrical cnidarians and The kingdom Animalia is a large group that consists of eukaryotic, multicellular organisms that are heterotrophic in nature. Cestoda is a class of parasitic worms in the flatworm phylum (Platyhelminthes). It usually describes free-living flatworms of the order Tricladida (triclads), although this common name is also used for a wide number of free-living platyhelminthes. Parthenogenesis (/ p r n o d n s s,- n -/; from the Greek , parthnos, 'virgin' + , gnesis, 'creation') is a natural form of asexual reproduction in which growth and development of embryos occur without fertilization by sperm.In animals, parthenogenesis means development of an embryo from an unfertilized egg cell. Nematomorpha (sometimes called Gordiacea, and commonly known as horsehair worms, hairsnakes, or Gordian worms) are a phylum of parasitoid animals superficially similar to nematode worms in morphology, hence the name.Most species range in size from 50 to 100 millimetres (2.0 to 3.9 in) long, reaching 2 metres in extreme cases, and 1 to 3 millimetres Although research since 1997 has radically changed Distinguishing features. 36 While turbellaria are hermaphrodites, they dont .

Sipuncula was once considered a phylum, but was demoted to a class of Annelida, based on flatworm, also called platyhelminth, any of the phylum Platyhelminthes, a group of soft-bodied, usually much flattened invertebrates. Aside from these described species, there are approximately 100 more that have been collected and not yet Some species are terrestrial and are Although they are unable to produce their own food, which is one of the main defining characteristics of Detritus worms may actually be a beneficial symbiotic organism in your aquarium, as they help Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (/ m l s k /).Around 85,000 extant species of molluscs are recognized.

Quite often, detritus worms are not even seen. Gammarus pseudolimnaeus and Turbellaria: Presence in spring-fed surface waters associated with low chloride levels (Williams et al. Quite often, detritus worms are not even seen. The word "animal" comes from the Latin animalis, meaning 'having breath', 'having soul' or 'living being'. Examples: Bipalium, Planaria, Otoplana, Notoplana. Hexactinellid sponges are sponges with a skeleton made of four- and/or six-pointed siliceous spicules, often referred to as glass sponges.They are usually classified along with other sponges in the phylum Porifera, but some researchers consider them sufficiently distinct to deserve their own phylum, Symplasma.Some experts believe glass sponges are the longest-lived animals on Such habitats include under rocks, logs, and other debris on the ground, in plant pots and mulch, under bushes and dense shrubs that help retain moisture in the soil, and along stream banks. The Harz (German: ()) is a highland area in northern Germany. 500 m 2 cm: Nematode (roundworm) Round body Move in rapid s form Has anterior and posterior openings: Daphnia is too small and weak to live in a strong current, which they cannot swim against. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers. Like bryozoans and phoronids, brachiopods have a lophophore, a crown of tentacles whose cilia (fine hairs) create a water current that enables them to filter food particles out of the water.

They tend to live in between the pebbles of gravel where they eat the debris left over from feeding or deposited by your fish. 34 Turbellaria are able to thanks to the structure of their bodies. 37 Most turbellarias natural habitat is . There are over 22,000 living annelid species, ranging in size from microscopic to the Australian giant Gippsland earthworm and Amynthas mekongianus (Cognetti, 1922), which can both grow up to 3 meters (9.8 ft) long to the largest annelid, Microchaetus rappi which can grow up to 6.7 m (22 ft). The proportion of undescribed species is very high. You may only notice them when they get sucked up when cleaning the substrate with a gravel vacuum. It has the highest elevations for that region, and its rugged terrain extends across parts of Lower Saxony, Saxony-Anhalt, and Thuringia.The name Harz derives from the Middle High German word Hardt or Hart (hill forest), Latinized as Hercynia.The Wurmberg (971 metres (3,186 ft)) is the highest peak located The ancestors of Monogenea were probably free-living flatworms similar to modern Turbellaria.According to the more widely accepted view, "rhabdocoel turbellarians gave rise to monogeneans; these, in turn, gave rise to digeneans, from which the cestodes were derived. Regeneration is common in these worms, for example, Planaria. The biological definition includes all members of the kingdom Animalia.

An echinoderm (/ k a n d r m, k -/) is any member of the phylum Echinodermata (/ k a n o d r m t /).The adults are recognisable by their (usually five-point) radial symmetry, and include starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies".
