The centipede is a speedy, carnivorous invertebrate that is generally found around decaying matter all around the world. Centipedes are not only carnivorous animals but the bite of the centipede also contains venom which means that the centipede kills its prey before eating it.
Cnidaria are diploblastic animals; in other words, they have two main cell layers, while more complex animals are triploblasts having three main layers. The two main cell layers of cnidarians form epithelia that are mostly one cell thick, and are attached to a fibrous basement membrane, which they secrete.
Jellyfish and comb jellies are gelatinous animals that drift through the ocean's water column around the world. They are both beautiful—the jellyfish with their pulsating bells and long, trailing tentacles, and the comb jellies with their paddling combs generating rainbow-like colors.
In 1986, Copenhagen University researcher Dr Jørgen Olesen and his colleagues collected these unusual organisms at 400 and 1,000 m deep on the Australian continental slope off eastern Bass Strait and Tasmania, and only just now described them as two species in a new genus, Dendrogramma, in the new family, Dendrogrammatidae.
The closest is the Dinosaur Genera List, compiled by biological nomenclature expert George Olshevsky, which was first published online in 1995 and is regularly updated. The most authoritative general source in the field is the second (2004) edition of The Dinosauria.
Echinoderms are hosts to various symbiotic animals such as the crinoid clingfish (Discotrema crinophila), the elegant squat lobster (Allogalathea elegans) or the crinoid shrimp (Periclimenes sp.). These animals receive shelter and food (left over) and also feed on microorganisms living on feather stars.
Flatworm, also called platyhelminth, any of the phylum Platyhelminthes, a group of soft-bodied, usually much flattened invertebrates. A number of flatworm species are free-living, but about 80 percent of all flatworms are parasitic—i.e., living on or in another organism and securing nourishment from it.
Leeches are segmented parasitic or predatory worm-like animals that belong to the phylum Annelida and comprise the subclass Hirudinea. They are closely related to the oligochaetes, the earthworms, and like them have soft, muscular, segmented bodies that can lengthen and contract.
This is a partial list of edible molluscs. Molluscs are a large phylum of invertebrate animals, many of which have shells. Edible molluscs are harvested from saltwater, freshwater, and the land, and include numerous members of the classes Gastropoda (snails), Bivalvia (clams, scallops, oysters etc.), Cephalopoda (octopus and squid), and Polyplacophora (chitons).
The Parazoa, are a proposed clade of animals. Traditionally, Parazoa, literally translated as "beside the animals", only consisted of Porifera and the Placozoa. It still is a basal animal group, but has been refuted in the original sense (i.e. as sister of the Eumetazoa).
And about 150 other species of alligators, crocodiles, lizards, snakes, turtles, and tortoises. You'll encounter them all at the Saint Louis Zoo. Next time you visit the Zoo, be sure to look for our reptiles at the Herpetarium and the Emerson Children's Zoo.
The rotifers (Rotifera, commonly called wheel animals) 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 Antonie van Leeuwenhoek in 1703.
Roundworm symptoms. The symptoms depend on the types (species) of roundworm causing the infection. Many affected people have no symptoms. Heavy roundworm infection in children can cause nutritional problems resulting in poor growth and poor general well-being. Some affected people may develop one or more of the following: High temperature (fever).
Depending on the species, sea cucumbers have between ten and thirty such tentacles and these can have a wide variety of shapes depending on the diet of the animal and other conditions. Many sea cucumbers have papillae, conical fleshy projections of the body wall with sensory tube feet at their apices.
The sea urchin is found across the ocean floors worldwide, but rarely in the colder, polar regions. Sea urchins are commonly found along the rocky ocean floor in both shallow and deeper water and sea urchins are also commonly found inhabiting coral reefs.There...
Starfish, or more technically accurate, sea stars, are fascinating creatures and amazingly diverse. Most commonly thought of as a five-armed intertidal species, starfish come in myriad shapes, sizes, colors, arm counts, and are found from shorelines to the deep sea.
The animals have no known specialized organs of circulation or respiration; the tardigrade’s body cavity is filled with fluid that transports blood and oxygen (the latter of which diffuses through the animal’s integument and is stored in cells within the hemocoel).
