Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton.They range in length from less than 0.5 mm (0.02 in) up to 2 to 3 metres (6.6 to 9.8 ft) in the 'giant' species such as the giant Gippsland earthworm (Megascolides australis) and the Mekong worm (Amynthas mekongianus).
The other subspecies (Ch. l. limnaei) attaches itself externally to the body of snails or to the inside of their shell (Lymnaea, Physa, Ancylus, Australorbis and many other genera [3]) and can freely move (so-called commensal ectosymbiosis). It consumes various tiny organisms that it manages to suck in from its vantage point on its host.
Oligochaeta is a genus of Asian flowering plants in the tribe Cardueae within the family Asteraceae. [2] [3] [4] Oligochaeta is native to central, southern, and southwestern Asia. They are annual plants that grow in mountain and steppe habitat. [5]
The genus Archigetes Leuckart, 1878 is unique among all tapeworms in that its species can mature in invertebrate hosts (Oligochaeta), in contrast to all other cestodes which have a vertebrate host. All five species were described as plerocercoids in oligochaetes, but two of them were also described as adults in cypriniform fishes.
Opisthopora is an order of mostly terrestrial worms. [1] [2]It is an order of the subclass Oligochaeta, which is distinguished by meganephridiostomal, male pores which open posteriorly to the last testicular segment. [3]
The Haplotaxida are one of two orders within the annelid subclass Oligochaeta, the other being the Lumbriculida. [1] No real common name exists, but they are simply referred to as haplotaxids . Given that the other clitellatan annelids are embedded between and around the Haplotaxida and Lumbriculida, the traditional Oligochaeta are a ...
Today, Mexico’s most commonly spoken languages are Spanish and Nahuatl, an Uto-Aztecan language. Hayes-Bautista says your narrative, your family’s narrative and the part you have in that make ...
Limnodrilus hoffmeisteri is conveyor-belt feeder that ingests particles in deep sediments and egests them on the sediment surface in the form of pseudofeces. [5] [6] The activities of this worm can alter sediment stratification, [6] [7] [8] increase the water content and porosity of sediment, [9] change the distribution of sediment particle size, [6] [10] alter the oxygen and nutrient dynamics ...
