Brazilian Boidae hemipenis morphology: Macroscopic and histological aspects
Anatomia, Histologia, Embryologia, 2022AbstractFour genera of the Boidae family are found in Brazil: Eunectes, Corallus, Epicrates, and Boa. Male copulatory organs in snakes are located inside the tail and are called hemipenes. They are double structures in an inverted position that are exposed during copulation.

The evolution of sperm ultrastructure among Boidae (Serpentes)
Zoomorphology, 2008We investigate the evolution of sperm ultrastructure of three species of Boidae (Epicrates cenchria, Boa constrictor amarali, and Corallus hortulanus). Spermatozoa of these species are filiform consisting of a head region, containing the nucleus and acrosome complex, a midpiece, and a tail region subdivided into principal piece and endpiece ...

Chromosomes and the classification of the snakes of the family Boidae
Cytogenetic and Genome Research, 1968The chromosomes of the Indian rock python, <i>Python molurus</i> (sub-family Pythoninae), and the sand boa, <i>Eryx johni johni</i> (Boinae), were investigated and compared with those of <i>Boa constrictor </i>(Boinae).

Detection of pathogens in Boidae and Pythonidae with and without respiratory disease
Veterinary Record, 2013Respiratory diseases in boid snakes are common in captivity, but little information is available on their aetiology. This study was carried out to determine the occurrence of lung associated pathogens in boid snakes with and without respiratory signs and/or pneumonia.

On the Diets of Neotropical Treeboas (Squamata: Boidae: Corallus)1
South American Journal of Herpetology, 2012ABSTRACT. Nine species of the Neotropical boid genus Corallus are distributed from southeastern Guatemala to southeastern Brazil. Based largely on previously published papers, we accumulated 271 prey records for all species combined, and they comprised 2 frogs, 69 lizards (mostly Anolis), 1 snake, 65 birds, and 134 mammals (marsupials, rodents, bats ...

Distribution and Variation in the Treeboa Corallus annulatus (Serpentes: Boidae)
Studies on Neotropical Fauna and Environment, 2001The arboreal boid Corallus annulatus has a disjunct distribution in tropical wet forests from extreme southeastern Guatemala to southwestern Ecuador (west of the Andes). The characters upon which subspecies (C. a. blombergi and C. a. colombianus) were described are shown to be of no diagnostic value.

Immune and hormonal regulation of the Boa constrictor (Serpentes; Boidae) in response to feeding
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2022Feeding upregulates immune function and the systemic and local (gastrointestinal tract) concentrations of some immunoregulatory hormones, as corticosterone (CORT) and melatonin (MEL), in mammals and anurans. However, little is known about the immune and hormonal regulation in response to feeding in other ectothermic vertebrates, especially snakes, in ...

Systematic Zoology, 1989
-Character congruence, the principle of using all the relevant data, and character independence are important concepts in phylogenetic inference, because they relate directly to the evidence on which hypotheses are based. Taxonomic congruence, which is agreement among patterns of taxonomic relationships, is less important, because its connection to the
