| six new species of coccidia (apicomplexa: eimeriidae) from east african chameleons (sauria: chamaeleonidae). | coprological examination of 83 east african chameleon specimens revealed 32.5% prevalence of coccidian parasites. six species are described as new: eimeria tilburyi n. sp. from chamaeleo jacksonii has cylindrical oocysts, 28.9 (26-33) x 16.0 (14-18) microm and occasionally a small polar granule. sporocysts are oval to ellipsoidal, 10.6 (9-12) x 7.2 (6-8) microm, without stieda and substieda bodies; endogenous stages were found in the gall bladder. oocysts of eimeria largeni n. sp. from chamaeleo ... | 2000 | 10780560 |
| a new species of choleoeimeria (apicomplexa: eimeriidae) from meller's chameleon, trioceros melleri (sauria: chamaeleonidae). | a captive specimen of meller's chameleon, trioceros melleri (gray), originally from tanzania and housed at the oklahoma city zoological park herpetarium, oklahoma county, oklahoma, was found to be passing an undescribed species of choleoeimeria in its feces. oocysts of choleoeimeria steveuptoni n. sp. were cylindroidal, 38.5 × 17.8 (36-42 × 17-19) µm with a bilayered wall and a shape index (length/width) of 2.2. a micropyle and oocyst residuum were absent, but a fragmented polar granule was ofte ... | 2012 | 22591017 |

| evidence for an elastic projection mechanism in the chameleon tongue. | to capture prey, chameleons ballistically project their tongues as far as 1.5 body lengths with accelerations of up to 500 m s(-2). at the core of a chameleon's tongue is a cylindrical tongue skeleton surrounded by the accelerator muscle. previously, the cylindrical accelerator muscle was assumed to power tongue projection directly during the actual fast projection of the tongue. however, high-speed recordings of chamaeleo melleri and c. pardalis reveal that peak powers of 3000 w kg(-1) are nece ... | 2004 | 15209111 |
| gular pouch diversity in the chamaeleonidae. | numerous chameleon species possess an out-pocketing of the trachea known as the gular pouch. after surveying more than 250 specimens, representing nine genera and 44 species, we describe two different morphs of the gular pouch. species of the genera bradypodion and chamaeleo, as well as trioceros goetzei, all possess a single gular pouch (morph one) formed from ventral expansion of soft tissue where the larynx and trachea meet. furcifer oustaleti and furcifer verrucosus possess from one to four ... | 2020 | 31680478 |
