Indotyphlus
''Indotyphlus'' is a small genus of caecilians in the family Grandisoniidae. As caecilians in general, they superficially resemble earthworms. The genus is endemic to the Western Ghats, India. They are sometimes known as Battersby's caecilians. Description ''Indotyphlus'' are small caecilians, with the largest specimen (a female ''Indotyphlus battersbyi'') measuring in total length. The eyes are visible in sockets, instead of under bone. Other diagnostic characters are absence of Temporal bone, temporal Fossa (anatomy), fossae, Chondrocranium, mesethmoid not being exposed dorsally, presence of splenial teeth, secondary grooves, and scales, tentacular opening that is closer to the eye than to the external nostril, no unsegmented terminal shield, smallish narial plugs on tongue, absence of diastema between vomerine and palatine teeth, and absence of terminal keel. Development is probably direct, without aquatic larvae. Habitat The genus is unusual among caecilians in that both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indotyphlus Maharashtraensis
''Indotyphlus maharashtraensis'' is a species of caecilians described in 2004 by scientists of Bombay Natural History Society and the Natural History Museum, London. It is only the second species of ''Indotyphlus'' known to science, and only known from its type locality near Humbarli village, Satara District, in the Western Ghats of Maharashtra, India. Common names Humbarli caecilian, Maharashtra caecilian, and Konkan tail-less caecilian have been coined for it. Description The type series consists of 12 specimens, including three males measuring and seven females measuring in total length; two smaller specimens could not be reliably sexed. The mid-body width of the larger specimens is about . The body is subcylindrical, slightly dorsoventrally compressed. The eyes are visible through the skin and appear as small dark spots. The tentacles are short, globular, and closer to the eye than the nostril. There are 124–133 primary annuli. The body has mostly brownish dorsal grou ...

Grandisoniidae
The Grandisoniidae are a family of common caecilians found in Africa, Seychelles and India. Like other caecilians, they superficially resemble worms or snakes. The family was formerly known as Indotyphlidae. Taxonomy The genera in this family were originally placed in family Caeciliidae. In 2011, the genera '' Gegeneophis'', '' Grandisonia'', '' Hypogeophis'', '' Idiocranium'', ''Indotyphlus'', '' Praslinia'' and ''Sylvacaecilia'' were segregated into family Indotyphlidae, named after the tribe Indotyphlini, which was used by Lescure et al (1986) for the Indian genera, ''Gegeneophis'' and ''Indotyphlus''. However, it was later pointed out that the name Grandisoniidae is the appropriate family-group name because, according to rules of the Nomenclatural Code, a name published at higher rank, Grandisoniinae, has precedence over a name of lower rank published in the same work, Indotyphlini.Dubois, Ohler, and Pyron, 2021, Megataxa, 5: 1–738 Genera and species *Genus '' Gege ...

Indotyphlus Battersbyi
Battersby's caecilian (''Indotyphlus battersbyi'') is a slender species of caecilian endemic to the Western Ghats, India. It has a flesh-coloured body, making it look very much like a large earthworm. Description The eyes of Battersby's caecilian are concealed under the skin and are feebly visible. It is also known as the tailless caecilian, as the body ends in a blunt shield. The vent in this species is transverse as opposed to longitudinal in most other species of Indian caecilians. The total length is . Distribution and status Battersby's caecilian is distributed in the Western Ghats in Maharashtra and Kerala (India). The population is unknown and threats are also not well known but are thought to be land changes for agriculture, wood and timber extracting by locals, road construction, agrochemical soil pollution and fires. It occurs in Sanjay Gandhi National Park and may occur in Koyna Wildlife Sanctuary and Phansad Wildlife Sanctuary. Eponym Battersby's caecilian is nam ...

Caecilian
Caecilians (; ) are a group of limbless, vermiform or serpentine amphibians. They mostly live hidden in the ground and in stream substrates, making them the least familiar order of amphibians. Caecilians are mostly distributed in the tropics of South and Central America, Africa, and southern Asia. Their diet consists of small subterranean creatures such as earthworms. All modern caecilians and their closest fossil relatives are grouped as a clade, Apoda , within the larger group Gymnophiona , which also includes more primitive extinct caecilian-like amphibians. The name derives from the Greek words γυμνος (''gymnos'', naked) and οφις (''ophis'', snake), as the caecilians were originally thought to be related to snakes. The body is cylindrical dark brown or bluish black in colour. The skin is slimy and bears grooves or ringlike markings. Description Caecilians completely lack limbs, making the smaller species resemble worms, while the larger species, with lengths up ...

Edward Harrison Taylor
Edward Harrison Taylor (April 23, 1889 – June 16, 1978) was an American herpetologist from Missouri. Family Taylor was born in Maysville, Missouri, to George and Loretta Taylor. He had an older brother, Eugene. Education Taylor studied at the University of Kansas in Lawrence, Kansas, graduating with a B.A. in 1912. Field trips during his time at the University of Kansas with Dr. Clarence McClung and Dr. Roy Moody helped prepare Taylor for his future endeavors. Between 1916 and 1920 he returned briefly to Kansas to finish his M.A. Career Upon completing his bachelor's degree, Taylor went to the Philippines, where at first he held a teacher's post in a village in central Mindanao. He collected and studied the local herpetofauna extensively and published many papers. He returned to the Philippines after completing his master's degree and was appointed Chief of Fisheries in Manila. On his many survey trips he continued collecting and studying fishes and reptiles of the islan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diastema
A diastema (plural diastemata, from Greek διάστημα, space) is a space or gap between two teeth. Many species of mammals have diastemata as a normal feature, most commonly between the incisors and molars. More colloquially, the condition may be referred to as gap teeth or tooth gap. In humans, the term is most commonly applied to an open space between the upper incisors (front teeth). It happens when there is an unequal relationship between the size of the teeth and the jaw. Diastemata are common for children and can exist in adult teeth as well. In humans Causes 1. Oversized Labial Frenulum: Diastema is sometimes caused or exacerbated by the action of a labial frenulum (the tissue connecting the lip to the gum), causing high mucosal attachment and less attached keratinized tissue. This is more prone to recession or by tongue thrusting, which can push the teeth apart. 2. Periodontal Disease: Periodontal disease, also known as gum disease, can result in bone loss that ...

Amphibian Genera
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic ...

Chondrocranium
The chondrocranium (or ''cartilaginous neurocranium'') is the primitive cartilage, cartilaginous skeleton, skeletal structure of the fetal skull that grows to envelop the rapidly growing embryonic brain.Salentijn, L. ''Biology of Mineralized Tissues: Prenatal Skull Development'', Columbia University College of Dental Medicine post-graduate dental lecture series, 2007 The chondrocranium in different species can vary greatly, but in general it is made up of five components, the sphenoids, the mesethmoid, the occipitals, the optic capsules and the nasal capsules. In humans, the chondrocranium begins forming at 28 days from mesenchyme, mesenchymal condensations and is fully formed between week 7 and 9 of fetal development. While the majority of the chondrocranium is succeeded by the bony skull, some components do persist into adulthood. In Chondrichthyes, cartilaginous fishes (e.g. sharks and Batoidea, rays) and agnathans (e.g. lampreys and hagfish), the chondrocranium persists through ...
