A phylogeny of Central African Boaedon (Serpentes: Lamprophiidae), with the description of a new cryptic species from the Albertine Rift
TLDR
The Albertine Rift lineage is described as a new species of Central African house snake Boaedon olivaceus and the poorly known taxon Lycodonomorphus subtaeniatus upembae is elevated to full species status and transferred to the genus Boaed on. Expand
Evolutionary origin and development of snake fangs
TLDR
A new model is put forward for the evolution of snake fangs: a posterior subregion of the tooth-forming epithelium became developmentally uncoupled from the remaining dentition, which allowed the posterior teeth to evolve independently and in close association with the venom gland, becoming highly modified in different lineages. Expand
The evolution of venom-delivery systems in snakes
TLDR
Several major morphological changes occurred early in colubroid evolution: a Duvernoy's gland evolved, the posterior maxillary teeth became specialized relative to the anterior max- illary teeth, and the attachment of the pterygoideus muscle moved forward to a position associated with the posteriormaxillary teeth.

How snakes eat snakes: the biomechanical challenges of ophiophagy for the California kingsnake, Lampropeltis getula californiae (Serpentes: Colubridae).
TLDR
It is found that the predator snake forces the vertebral column of the prey snake to bend into waves, which shorten the prey's body axis and allow it to fit inside the gastrointestinal (GI) tract and body cavity of the predator. Expand
Post-ovipositional development of the monocled cobra, Naja kaouthia (Serpentes: Elapidae).
External morphological development between oviposition and hatching of the monocled cobra, Naja kaouthia, is described. Ten developmental stages are diagnosed according to nine features. TheseExpand

TLDR
A new idea argues that a heterochronic mechanism (alteration of the timing of developmental events) may provide the answer that the ungrooved and grooved teeth of colubrid snakes evolved from an ancestral tubular fang by means of attachment of replacement Tubular fangs to the maxilla at an earlier developmental stage than usual (precocial ankylosis).

Morphology and ultrastructure of possible integumentary sense organs in the estuarine crocodile (Crocodylus porosus)
TLDR
The morphology of the ISOs suggests that sensory organs on the amniote integument have a mechanosensory function, and the structure of ISOs, in Crocodylus porosus, suggests that they are sensory organs. Expand
Snake venom: From fieldwork to the clinic
TLDR
Snake venoms are recognized here as a grossly under‐explored resource in pharmacological prospecting and must be combined with other disciplines if the full potential of snake venom‐derived medications is to be realized. Expand
Phylogeny and biogeography of the African burrowing snake subfamily Aparallactinae (Squamata: Lamprophiidae).
TLDR
Biogeographic analyses suggested that the Zambezian biogeographic region, comprising grasslands and woodlands, facilitated radiations, vicariance, and dispersal for many aparallactines and elevate a lineage of Polemon to full species status. Expand
How tubular venom‐conducting fangs are formed

  • 1 June 2002
TLDR
All fangs examined, elapid and viperid, embryos and adults, were found to develop into their tubular shape by the addition of material to the basal end of the tooth rather than by the folding inward of an ungrooved tooth to form a tubular fang. Expand
