The Lumbricidae are a family of earthworms. About 33 lumbricid species have become naturalized around the world, but the bulk of the species are in the Holarctic region: from Canada and the United States and throughout Eurasia to Japan. An enigmatic species in Tasmania is Eophila eti. Currently, 670 valid species and subspecies in about 42 genera are recognized. This family includes the majority of earthworm species well known in Europe and Asia.
Oligochaeta is a subclass of soft-bodied animals in the phylum Annelida, which is made up of many types of aquatic and terrestrial worms, including all of the various earthworms. Specifically, oligochaetes comprise the terrestrial megadrile earthworms, and freshwater or semiterrestrial microdrile forms, including the tubificids, pot worms and ice worms (Enchytraeidae), blackworms (Lumbriculidae) and several interstitial marine worms.
Megascolecidae is a family of earthworms native to Madagascar, Australia, New Zealand, Asia, and North America. All species of the Megascolecidae belong to the Clitellata class. The Megascolecidae comprise a large family of earthworms and they can grow up to 2 meters in length. The intercontinental distribution of Megascolecidae species favours the continental drift theory.
The Platycnemididae are a family of damselflies. They are known commonly as white-legged damselflies. There are over 400 species native to the Old World. The family is divided into several subfamilies.
Spenceriella is a genus of worms in the family Megascolecidae that is now included in the prior genus Anisochaeta although some other species are transferred to Celeriella.
Anisochaeta gigantea, commonly called the North Auckland worm, is a rare giant annelid of the family Megascolecidae, endemic to New Zealand.
Peucedanum is a genus of flowering plant in the carrot family, Apiaceae. Peucedanum boasts a global presence with diverse spread of morphological features. Peucedanum species are characterized by dorsally compressed mericarps, slightly prominent dorsal ribs, narrowly winged lateral ribs, and a broad commissure. However, the vast diversity of morphology, fruit forms, and phytochemical production makes classifying species in the Peucedanum challenging. Historically relevant in traditional medicine, Peucedanum's taxonomic complexity arises from its extensive diversity.
The Himalayan striped squirrel, also known as western striped squirrel or Burmese striped squirrel, is a species of rodent in the family Sciuridae. It lives in a variety of forest from tropical to subtropical in Bhutan, Cambodia, China, India, Laos, Malaysia, Myanmar, Nepal, Thailand, and Vietnam. This species is diurnal, arboreal and feeds on fruit, vegetable matter, and insects. It often seen in small groups and uses tree holes for shelter.
Pheretima is a genus of earthworms found mostly in New Guinea and parts of Southeast Asia.
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms.
Amynthas is a genus of earthworms in the family Megascolecidae. They are known as jumping worms, snake worms, or crazy worms because of their erratic thrashing behaviour when disturbed. The genus is native to East Asia, but they are invasive in many areas of the United States. They are a matter of concern in many states, as they disrupt the native forest ecology by affecting soil structure and chemistry.
Composita is an extinct brachiopod genus that lived from the Late Devonian to the Late Permian. Composita had a cosmopolitan global distribution, having lived on every continent except Antarctica. Composita had a smooth shell with a more or less distinct fold and sulcus and a round opening for the pedicle on the pedicle valve. Composita is included in the family Athyrididae and placed in the subfamily Spirigerellinae.
Glyphidrilus is a genus of semi-aquatic freshwater earthworms in the family Almidae. It inhabits freshwater systems like river banks, lakes and rice fields from East Africa to South and South East Asia.
Samuel James is an American scientist, a researcher specializing in evolutionary biology, focusing on earthworm taxonomy. James, with fellow researchers, has discovered numerous species of annelids, including Diplocardia californiana, Diplocardia woodi, Diplocardia montana, and a new species related to the Giant Palouse earthworm.
Octochaetus multiporus, commonly known as the New Zealand earthworm, is a megascolecid worm endemic to New Zealand. It is mainly found in the south of Manawatu but may also be found along the east coast of the South Island. A bioluminescent worm, Octochaetus multiporus secretes a luminescent fluid from its mouth when disturbed or punctured.
Megascolides is a genus of earthworms in the family Megascolecidae.
Eiseniella is a genus of Lumbricidae.
Microscolex is a genus of annelids belonging to the family Acanthodrilidae. The genus has cosmopolitan distribution.
Emertonia is a genus of copepods in the family Paramesochridae.
Polypheretima is a genus of annelid earthworms belonging to the family Megascolecidae, erected by Wilhelm Michaelsen in 1934. Species have been recorded mostly from Africa and Asia, with several apparently very locally endemic.
