By nature, Uromastyx are herbivorous but in younger age love to eat insects and small animals. Uromastyx borrows in desert, rocky and hilly areas. Size of Uromastyx is up to 91cm in adults and 10cm in neonates. Oil of Uromastyx is used for treatment of different disease. Aim of current study was to investigate fatty acid composition and seasonal variations in biochemical and hormonal profile. In two different seasons five samples of Uromastyx were collected and then fat extraction process done in laboratory, from fats of Uromastyx pure fats oil was extracted with Folch method by using chloroform and methanol in 2/1 ratio. GC-MS technique was used for analysis. From five samples, twenty-three fatty acids were identified and percentage of saturated fatty acids was 47.8% while unsaturated fatty acids were 30.4%. Benzenedicarboxlic, an aromatic fatty acid was present in all five samples of two seasons. Metabolites of vitamin B-12 were also identified in it. Hormonal studies of all three parameters luteinizing hormone, follicle stimulating hormone and cortisol were same except testosterone which was high in samples of December month. Study of fatty acids and hormonal profile of different seasons conclude that saturated fatty acids were higher as compared to unsaturated fatty acids. Sample of month December 2140 IJBPAS, November, 2019, 8(11) Malik A et al Research Article values of saturated fatty acids were lower as compared to October and similarly testosterone level were higher in December with all other parameters remained same.

  • Uromastyx by Catherine Love, DVM Updated 2021
    Uromastyx By Catherine Love, DVM Updated 2021 Natural History Uromastyx, also known as spiny-tailed or dabb lizards, are a genus of herbivorous, diurnal lizards found in northern Africa, the Middle East, and northwest India. This genus of lizard is in the agamid family, the same family as bearded dragons and frilled lizards. There are 13 recognized uromastyx species, but not all are commonly kept in captivity in the United States. U. aegyptia (Egyptian), U. ornatus (ornate), U. geyri (saharan), U. nigriventris (Moroccan), U. dispar (Mali), and U. ocellata (ocellated) are some of the most commonly kept. Uros dig burrows or spend time in rocky crevices to protect themselves from the elements in their desert habitats. These lizards naturally inhabit rocky terrain in very arid climates and are often found basking in direct sunlight. Characteristics and Behavior Uros tend to be quite docile and tolerant of handling, with some owners even claiming their lizard seeks out interaction. These lizards don’t tend to bite, but can be skittish if time is not taken to tame them. Ornate uromastyx have been noted to be bolder, while Egyptian and Moroccan uromastyx may be more shy. As with other members of the agamid family, uromastyx do not possess tail autotomy (they can’t drop their tails). Uros are heat loving, mid-day basking lizards that thrive in arid environments. Uros have a gland near their nose that excretes salt, which may cause a white build-up near their nostrils (keepers affectionately refer to this build-up as “snalt”). They are fairly hardy and handleable lizards that make good pets for intermediate keepers.

SUMMARY Uromastyx ocellata, commonly known in the pet trade as the Ocellated Spiny-tailed Lizard, is recorded from Djibouti, Egypt, Eritrea, Somalia and Sudan. Ethiopia’s CITES Scientific Authority also report that the species is found in that country. It is found in wadis in rocky mountainous desert with acacia trees. U. ocellata is reportedly fairly common in some range States, although regarded as declining in some areas. If it occurs at population densities comparable to those of other Uromastyx species, its population is likely to number at minimum several hundred thousand individuals. Reported exports of U. ocellata during the period 1994-2003 were mainly from Sudan (11,702) and Egypt (4,528) with Ethiopia also exporting specimens.

Moscow, Russia Abstract Molecular phylogeny of the reptiles does not accept the basal split of squamates into Iguania and Scleroglossa that is in conflict with morphological evidence. The classical phylogeny of living reptiles places turtles at the base of the tree. Analyses of mitochondrial DNA and nuclear genes join crocodilians with turtles and places squamates at the base of the tree. Alignment of the reptiles’ ITS2s with the ITS2 of chordates has shown a high extent of their similarity in ancient conservative regions with Cephalochordate Branchiostoma floridae, and a less extent of similarity with two Tunicata, Saussurea tunicate, and Rinodina tunicate. We have performed also an alignment of ITS2 segments between the two break points coming into play in 5.8S rRNA maturation of Branchiostoma floridaein pairs with orthologs from different vertebrates where it was possible. A similarity for most taxons fluctuates between about 50 and 70%. This molecular analysis coupled with analysis of phylogenetic trees constructed on a basis of manual alignment, allows us to hypothesize that primitive chordates being the nearest relatives of simplest vertebrates represent the real base of the vertebrate phylogenetic tree.

The research aimed to study halal and haram of reptiles by tracing manuscripts of Islam and science, combining, analyzing, and drawing conclusions with species Uromastyx aegyptia (Desert lizard), Varanus salvator (Javan lizard), and Draco volan (Klarap). The results showed that Dhab (Uromastyx aegyptia) (Desert lizard) is halal, based on the hadith narrated by Muslim no. 3608, hadith narrated by Al-Bukhari no. 1538, 1539. Uromastyx aegyptia are herbivorous animals although sometimes they eat insects. Javanese lizards (Varanus salvator) in Arabic called waral, wild and fanged animals is haram for including carnivores, based on hadith narrated by Muslim no. 1932, 1933, 1934, hadith narrated by Al-Bukhari no. 5530. Klarap (Draco volans)/cleret gombel/gliding lizard is possibly halal because no law against it. Draco volans is an insectivorous, not a wild or fanged animal, but it can be haram if disgusting.

  • Checklist of Amphibians and Reptiles of Morocco: a Taxonomic Update and Standard Arabic Names
    Herpetology Notes, volume 14: 1-14 (2021) (published online on 08 January 2021) Checklist of amphibians and reptiles of Morocco: A taxonomic update and standard Arabic names Abdellah Bouazza1,*, El Hassan El Mouden2, and Abdeslam Rihane3,4 Abstract. Morocco has one of the highest levels of biodiversity and endemism in the Western Palaearctic, which is mainly attributable to the country’s complex topographic and climatic patterns that favoured allopatric speciation. Taxonomic studies of Moroccan amphibians and reptiles have increased noticeably during the last few decades, including the recognition of new species and the revision of other taxa. In this study, we provide a taxonomically updated checklist and notes on nomenclatural changes based on studies published before April 2020. The updated checklist includes 130 extant species (i.e., 14 amphibians and 116 reptiles, including six sea turtles), increasing considerably the number of species compared to previous recent assessments. Arabic names of the species are also provided as a response to the demands of many Moroccan naturalists. Keywords.

E-mail: luisfelipe. lopez@biologia. ulpgc. es Abstract: The description of a new species ofthe genus Uromastyx is proposed on the basis oftwo specimens from the Adrar Souttouf in Western Sahara. This taxon differs greatly from U. acanthinura on account its larger size, the much larger number of scales, the arrangement of tubercules on its upper thighs, the different habitus and colouring. These morphological features mean it closely resembles U. aegyptia. The existence of a relictual U. aegyptia-group throughout the Sahara is suggested. In addition, the morphological variations in Spiny-tailed agamas (or Mastigures) ofthe Uromastyx acanthinura group in the west ofthe Sahara are briefl y analysed. This produces evidence for the existence of a species proper to Western Sahara and surrounding areas, Uromastyx jlavifasciata, represented by two subspecies: U. f jlavifasciata in the north and U. f obscura subsp. nov. in the south. The latter new form is characterised by uniformly black colouring, even in active individuals. This work also demonstrates that Uromastyx acanthinura werneri does not penetrate Western Sahara and that its distribution is parapatric with that of U.
