Morphology Reproduction Additional Readings Nematomorpha - AccessScience from McGraw-Hill Education https://www.accessscience.com/content/nematomorpha/447300 (https://www.accessscience.com:443/) Article by: Muus, Bent J. Danish Institute for Fishery and Marine Research, Charlottenlund, Denmark. Publication year: 2014 DOI: http://dx.doi.org/10.1036/1097-8542.447300 (http://dx.doi.org/10.1036/1097-8542.447300) Content Morphology Reproduction Additional Readings A phylum of worms formerly considered to be a class of the phylum Aschelminthes; commonly called the hairworms, and closely allied to the nematodes. The adults are free-living in aquatic habitats, while the juveniles are parasitic in arthropods. The nematomorphs are found all over the world. They are divided into two classes, the Nectonematoidea and Gordioidea, with a total of 225 species. See also: Nemata (nematoda) (/content/nemata-nematoda/447050) Morphology The body is long and slender with a maximum length of 5 ft (1.5 m) and a diameter of 0.02–0.12 in. (0.5–3 mm). The females are longer than the males. The anterior end is rounded with a dark pigmented ring and a terminal mouth. The posterior end may be rounded with a terminal cloaca, or it may form two or three lobes in a forklike structure. The body color is yellowish, brown, or almost black. The body wall consists of three layers: an outer, rather thick fibrous cuticle; an epidermis consisting of a single layer of cells; and innermost, a muscle layer with longitudinal fibers only. The surface of the cuticle may be smooth, or rough with rounded or polygonal thickenings called areoles. These may be flat or may form projecting structures, sometimes with bristles, and they may be perforated by pores and canals. Between the areoles run interareolar furrows, often with wartlike structures and bristles. Special natatory bristles are developed in Nectonema. The function of the areoles is unknown. Body cavity This cavity extends the length of the body. It may be filled with tissue so that only minor spaces are left around the digestive system and the gonads. The digestive tube is always more or less degenerated, and the anterior part is often a solid string of cells. Ingestion of food is impossible, and the intact part of the digestive system seems to be adapted for excretory functions. During the parasitic stage, food is obtained through the body surface by means of digestive enzymes. Nervous system This consists of a cerebral mass lying ventrally in the head and a ventral nerve cord which originates in the epidermal layer. Little is known of the sensory organs. Probably the bristles and warts of the cuticle have sensory functions. A rudimentary eye is found in Paragordius. Reproduction The sexes are always separate, and the gonads are paired and stringlike, extending the length of the body. In males, the gonads are connected with the cloaca by sperm ducts. In females, the ovaries form a large number of lateral diverticula in 1 of 3 7/27/2016 10:53 AM Nematomorpha - AccessScience from McGraw-Hill Education https://www.accessscience.com/content/nematomorpha/447300 which the eggs ripen. The oviducts enter the cloaca separately. A sac, which is called the seminal receptacle, extends anteriorly from the cloaca. During copulation, the male coils itself around the female and places a drop of sperm near her cloacal opening. The sperm cells actively enter the seminal receptable. The eggs are laid in water in strings, and the adults die after egg laying. When hatched, the larvae swim to an aquatic arthropod. They penetrate the body wall of the host by means of their characteristic proboscis, which is armed with hooks and three long stylets. The larvae of some species may secrete a special mucus in which they encyst until they are accidentally ingested by the right host, which may be a terrestrial insect. The development in the host lasts some months without any metamorphosis. When mature, the worms leave the host. Bent J. Muus Additional Readings A.

Estimates sug- gest that only 18% of hairworm species have been described globally and biodiversity studies on this group have been hindered by unreliable ways of collecting adult free living worms over large geographical areas. However, recent work indicates that non-adult cyst stages of hairworms may be the most commonly encountered stages of gordiids in the envi- ronment, and can be used for discovering the hidden diversity of this group. Unfortunately, little information is available on the morphological characteristics of non-adult stages of hairworms. To address this problem, we describe and compare morphological characteristics of non-adult stages for nine species of African and North American gordiids from four gen- era (Chordodes, Gordius, Paragordius, and Neochordodes).

DOI:10.4311/2019LSC0125 BIODIVERSITY FROM CAVES AND OTHER SUBTERRANEAN HABITATS OF GEORGIA, USA Kirk S. Zigler1C, Matthew L. Niemiller2, Charles D.R. Stephen3, Breanne N. Ayala1, Marc A. Milne4, Nicholas S. Gladstone5, Annette S. Engel6, John B. Jensen7, Carlos D. Camp8, James C. Ozier9, and Alan Cressler10 Abstract We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including 51 troglobionts (cave-obligate species), from more than 150 sites (caves, springs, and wells). Endemism is high; of the troglobionts, 17 (33 % of those known from the state) are endemic to Georgia and seven (14 %) are known from a single cave. We identified three biogeographic clusters of troglobionts. Two clusters are located in the northwestern part of the state, west of Lookout Mountain in Lookout Valley and east of Lookout Mountain in the Valley and Ridge. In addition, there is a group of tro- globionts found only in the southwestern corner of the state and associated with the Upper Floridan Aquifer. At least two dozen potentially undescribed species have been collected from caves; clarifying the taxonomic status of these organisms would improve our understanding of cave biodiversity in the state.

  • Hairworm Response to Notonectid Attacks
    ANIMAL BEHAVIOUR, 2008, 75, 823e826 doi:10.1016/j.anbehav.2007.07.002 Available online at www.sciencedirect.com Hairworm response to notonectid attacks MARTA I. SA´ NCHEZ*,FLEURPONTON*, DOROTHE´ EMISSE´ *,DAVIDP.HUGHES† &FRE´ DE´ RIC THOMAS* *GEMI, UMR CNRS/IRD, Montpellier yCentre for Social Evolution, Institute of Biology, Universitetsparken, Copenhagen (Received 20 March 2007; initial acceptance 11 May 2007; final acceptance 4 July 2007; published online 24 October 2007; MS. number: 9319) Very few parasite species are directly predated but most of them inherit the predators of their host. We explored the behavioural response of nematomorph hairworms when their hosts are preyed upon by one of the commonest invertebrate predators in the aquatic habitat of hairworms, notonectids. The hair- worm Paragordius tricuspidatus can alter the behaviour of its terrestrial insect host (the cricket Nemobius syl- vestris), causing it to jump into the water; an aquatic habitat is required for the adult free-living stage of the parasite. We predicted that hairworms whose hosts are captured by a notonectid should accelerate their emergence to leave the host before being killed. As predicted, the emergence length of the worm was sig- nificantly shortened in cases of notonectid predation, but the exact reason of this response seems to be more complex than expected. Indeed, experimental manipulations revealed that hairworms are remark- ably insensitive to a prolonged exposure to predator effluvia which notonectids inject into prey, so accel- erated emergence is not a protective response against digestive enzymes. We discuss other possibilities for the accelerated exit observed, ranging from unspecific stress responses to other scenarios requiring consid- eration of the ecological context.
