Chondrocranium and skeletal development of Phrynops hilarii (Pleurodira: Chelidae)
(Wiley, 2008-08)
The present study represents the first comprehensive contribution to the knowledge of the skeletal development of a pleurodiran turtle, Phrynops hilarii (Pleurodira, Chelidae). The most remarkable features found are: (1) ...
Nasal cartilages, hyobranchial apparatus, larynx, and glottal tubes in four species of Hydropsini (Serpentes: Dipsadidae: Xenodontinae)
(Senckenberg Gesellschaft für Naturforschung, 2014-04-30)
Tribe Hydropsini (Serpentes: Dipsadidae: Xenodontinae) consists of three genera of aquatic snakes, Helicops, Hydrops, and Pseudoeryx, in which cartilaginous cranial features have been poorly studied. We here describe the ...
Chondrocranium and cranial muscle morphology in Lysapsus and Pseudis tadpoles (Anura: Hylidae: Hylinae)
(Wiley Blackwell Publishing, Inc, 2006-04)
The chondrocranium and cranial muscles of Lysapsus limellum, Pseudis cardosoi, P. minuta and four subspecies of P. paradoxa (caribensis, occidentalis, paradoxa and platensis) are described. Lysapsus and Pseudis are related ...
Internal larval morphology of two species of shining leaf frogs (Anura: Phyllomedusidae: Phasmahyla)
(Sociedade Brasileira de Herpetologia, 2018-04)
We describe the buccal cavity and chondrocranial morphology of Phasmahyla cruzi tadpoles in comparison to P. guttata. We also provide a review of some characters for larval phyllomedusids and discuss some evolutionary ...
Larval Anatomy of Andean Toads of the Rhinella spinulosa Group (Anura: Bufonidae)
(Herpetologists League, 2020-07)
The Rhinella spinulosa group is a clade of toads that inhabit the Andes mountains from northern Ecuador to Patagonia. Its taxonomy was recently revised, and in its new arrangement comprises nine species, including Rhinella ...
Cranial antomy of tadpoles of five species of Scinax (Hylidae: Hylinae)
(Magnolia Press, 2011-03)
We studied the oral apparatus, buccal cavity and musculoskeletal features in tadpoles of five species of the genus Scinax (S. acuminatus, S. uruguayus, S. aff. pinima, S. aromothyella, and S. berthae). Observed variation ...
Larval Anatomy of Andean Toads of the Rhinella spinulosa Group (Anura: Bufonidae)
(Herpetologists League, 2020-04)
The Rhinella 22 spinulosa group is a clade of toads that inhabit the Andes mountains from northern Ecuador to Patagonia. Its taxonomy was recently revised, and in its new arrangement comprises nine species, including ...
Review of the internal larval anatomy of the Proceratophrys bigibbosa species group (Anura: Odontophrynidae), with description of the tadpole of P. brauni Kwet and Faivovich, 2001
(American Society of Ichthyologists and Herpetologists, 2019-07)
The systematic importance of larval characters of the Neotropical genus Proceratophrys has been demonstrated. We review the internal anatomy of the tadpoles of the monophyletic P. bigibbosa species group, provide the first ...
Comparative morphology of pond, stream and phytotelm-dwelling tadpoles of the South American Redbelly Toads (Anura: Bufonidae: Melanophryniscus)
(Wiley-Blackwell, 2014-07-01)
We present a comprehensive review of larval morphology in the Neotropical toad genus Melanophryniscus. The taxa studied included 23 species with representatives of recognized phenetic groups and different larval ecomorphological ...
Life on the edge: Tadpoles of Cycloramphidae (Amphibia; Anura), anatomy, systematics, functional morphology, and comments on the evolution of semiterrestrial tadpoles
(2021-08-01)
The evolutionary success of anurans can be partially explained by the occurrence of free-living larvae. Tadpoles occupy several distict habitats, including the terrestrial environment. Semiterrestriality appears to have ...
