The primitive characters of the urodeles are due to their retention of the larval features. 9. A single median protrusible copulatory organ (Phallodeum) in males, can be protruded through the cloaca, an indication of internal fertilization. The females pick up this packet and store the sperm in cloaca. 6. Development 5. C. alleganiensis with C.a. Palatines are reduced or absent in most genera. 12. an = without + oura = tail] Approx. McDiarmid (1993) reported the occurrence of 383 species under ten families. Tongue absent, hence called aglossal toad. A newly hatched larva possesses 3 pairs of external pinnate gills. 7.

Sacrum fused to the coccyx (Urostyle). Ichthyophis kohtaoensis typifies the biology of oviparous caecilians, so far as is known (see Himst-edt, 1996). Most of the primitive caecilians are oviparous but some advanced caeci­lians are viviparous (e,g., Typhlonectes). (1985) have created a separate order Ichthyostegalia for the earliest known tetrapods—Ichthyostega, Ichthyostegopsis and Acanthostega but Duellman and Trueb (1986) placed them under different families—Ichthyostegidae for Ichthyostega and Ichthyoste gopsis, and Acanthostegidae for the genus Acanthostega without creating a separate order.

It is found in Magdalene cave, near Adelsberg cave, Yugoslavia. Biju and Bossuyt (2003) created a new frog family from India that reveals an ancient biogeographical link with the Seychelles. They consider that early amphibians have evolved from groups of crossopterygians — may be specially mentioned Osteolepis and Eusthenopteron. 400 species. No. Lidless reduced eyes covered by the skin or by the maxillary bones. Family 4. After the injection of the patient’s urine, the female frog will respond by spawning within a few hours.

Presacral 8th vertebra is biconcave and the sacrum biconvex. Typhlomolge, Texas Blind Salamander, is found in deep caves and wells of Texas, U.S.A. The vertebra in which the centrum ossifies around the notochord is fused to the neu­ral and haemal arches. Omosternum and stemu bony in most genera. The colour of the dorsal part of the body is grey to brown or bluish black. Their conclusion is based on the following points: (i) In both cases the mode of egg laying habit is same. Results: We sequenced and characterized the Hox clusters of Banna caecilian (Ichthyophis bannanicus) with a strategy combining long range PCR and genome walking. 5. Four suborders are recognised provision­ally that include 9 living and 4 extinct families. 4. suffix): 1. lepos = a scale; spondlylos = vertebra, or shell-like or spool-shaped ver­tebra). 3. 4.

Mountain stream forms; O. japonicus and O. fischeri. The group became extinct at the close of the Permian and was represented by two groups (i) The water dwelling embolomeres e.g., Palaeoherpeton and the other group, more terrestrial seymouriamorph which had a large otic notch and a single occipital condyle (e.g., Seymouria). After a few weeks the larvae are found to swim in water. Andrias = (Megalobatrachus), 2 species occurs in China and Japan.

Panchen (1972) and McFarland et al., (1985) have separated the microsaurs from lepospondyls and have suggested that they should be considered a separate group. Padhye and Ghate (2002) overviewed the amphi­bian fauna in Maharashtra state. Ichthyophis hypocyaneus, the bantam caecilian, is a species of amphibian in the family Ichthyophiidae of caecilians, endemic to Indonesia.Until its rediscovery in 2000, it was known only from the 1827 type specimen..

[web application]. They are primitive caecilians. Two types of lineages are discerned among nectridians. Reproductive behaviour is associated with vocalizations, mostly in males. The proximal tarsal elements are elon­gated. 2. According to H. H. Newman (1939), the apodans are highly specialized for a burrow­ing life and are decidedly degenerate in many respects and they are regarded as the most primitive of modem Amphibia. The lower jaw was composed as many as ten elements. They are found in the cold mountain streams of Western North America.
