چکیده
In the present study, the morphological and morphometric characterization of two species of digenetic trematodes infecting the large intestines of the common chameleon Chamaeleo chamaeleon (Reptilia: Chamaeleonidae) were described by means of light microscopy as a first description. 30 and 37 out of 115 (26.1 % and 32.1%) of this lizard species were found to be naturally infected with Postorchigenes sp. (Trematoda: Lecithodendriidae) and Malagashitrema sp. (Trematoda: Homalometridae) respectively. Postorchigenes sp. possesses a body which is oval, spinulate with an oral sucker bigger than acetabulum. The prevalence of Postorchigenes sp. reported from the present study were agreed with the previous studies carried out by Kennedy et al. (1987) who described a three species of digenea from seven species of lizards in Idonesia. Malagashitrema sp. possesses oral sucker larger than acetabulum. The presence of Malagashitrema sp. proved that Malagashitrema is a genus with species linked to Chamaeleo spp. These trematodes adapted to different areas, making their presence are possible in different geographical regions in the world and appears to be a species adapted to Chamaeleo spp. [Kareem Morsy; Nadia Ramadan; Salam Al Hashimi; Medhat Ali; Abdel-Rahman Bashtar.

Visual Acuity and Optokinetic Directionality in the Common Chameleon (Chamaeleo chamaeleon)
Chameleons (Chamaeleo spp.) use vision in prey capture and in predator avoidance. They scan the environment with large amplitude, “independent”, eye movements and once a target has been sighted the eyes converge to a binocular fixation. To precisely determine target distance, chameleons uniquely employ accommodation effort of their negatively powered lenses. Our research aimed at determining th...
متن کاملEffect of cold temperature on the length of incubation of Chamaeleo chamaeleon
Common chameleon eggs spend the first months of incubation at low temperatures. I incubated eggs of different clutches at 25◦C in four treatments with respectively 0, 84, 119 and 149 days of initial cold period (at 14◦C). Treatments with longer cold periods had longer total incubation but shorter periods of incubation at 25◦C. Eggs which did not experience initial cold period showed low synchro...
متن کاملDevelopmental arrest during embryonic development of the common chameleon (Chamaeleo chamaeleon) in Spain.
Embryonic development of the common chameleon, Chamaeleo chamaeleon, was monitored from oviposition to hatching at a field site in southwestern Spain and in the laboratory under five experimental temperature regimes. Embryos were diapausing gastrulae at the time of oviposition; developmental arrest in the field continued as cold torpor during winter. Postarrest development in the field commence...
متن کاملNew species of Choleoeimeria (Apicomplexa: Eimeriidae) from the veiled chameleon, Chamaeleo calyptratus (Sauria: Chamaeleonidae), with taxonomic revision of eimerian coccidia from chameleons.
Coprological examination of 71 samples from a breeding colony of veiled chameleons, Chamaeleo calyptratus Duméril et Duméril, 1851, revealed a presence of two species of coccidia. In 100% of the samples examined, oocysts of Isospora jaracimrmani Modrý et Koudela, 1995 were detected. A new coccidian species, Choleoeimeria hirbayah sp. n., was discovered in 32.4% of samples from the colony. Its o...
