Hexametra Boddaertii
''Hexametra boddaertii'' is a parasitic roundworm belonging to the family Ascarididae. ''H. boddaertii'' was originally described from a single specimen of ''Mastigodryas boddaerti'', a South American colubrine snake. Other neotropical colubrids identified as hosts to ''H. boddaertii'' include '' Oxyrhopus trigeminus'', '' Philodryas patagoniensis'', '' Spilotes pullatus'', ''Trimorphodon biscutatus'', '' Philodryas baroni'', and ''Oxyrhopus guibei ''Oxyrhopus guibei'' is a species of snake in the family Colubridae. The species is endemic to South America. It is often called the false coral snake, Braz H, Manço DD (2011)"Natural nests of the false-coral snake ''Oxyrhopus guibei'' in sout ...''. It is thought that ''Hexametra'' may be the causative agent of ocular disease, diffuse unilateral subacute neuroretinitis, (DSUN), in Brazil.Souza et al., 2007 V.L. Souza, A.P. Santos T.M. d.

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over ...

Secernentea
Secernentea was a class of nematodes in the Classical Phylogeny System (Chitwood, 1958) and is no longer in use. This morphological-based classification system has been replaced by the Modern Phylogeny system, where taxonomy assignment is based on small subunit ribosomal DNA (SSU rDNA). Characteristics of Secernentea are: * Amphid apertures are pore/slit-like * Derids are present in some; located near nerve ring * Phasmids are present; posterior * Excretory system is tubular * Cuticle is striated in two to four layers; lateral field is present * Three esophageal glands; esophageal structure varies * Males generally have one testis * Caudal alae are common * Sensory papillae are cephalic only; may be caudal papillae in males * Mostly terrestrial * Rarely found in fresh or marine water Systematics Subclasses and orders of Secernentea are:Tree of Life Web Project (ToL) (2002)Nematoda.

Ascaridida
The order Ascaridida includes several families of parasitic roundworms with three "lips" on the anterior end. They were formerly placed in the subclass Rhabditia by some, but morphological and DNA sequence data rather unequivocally assign them to the Spiruria. The Oxyurida and Rhigonematida are occasionally placed in the Ascaridida as superfamily Oxyuroidea, but while they seem indeed to be Spiruria, they are not as close to ''Ascaris'' as such a treatment would place them.Tree of Life Web Project (ToL) (2002)Nematoda Version of 2002-JAN-01. Retrieved 2008-NOV-02. These "worms" contain a number of important parasites of humans and domestic animals. Important families include: * The Anisakidae are also called the "marine mammal ascarids". The larvae of these worms cause anisakiasis when ingested by humans in raw or insufficiently cooked fish, but do not reproduce in humans. * The Ascarididae include the giant intestinal roundworms (''Ascaris'' spp.). * The Cosmocercidae include ...
