Elapoidea
The Elapoidea are a Superfamily (biology), superfamily of snakes in the clade Colubroides, traditionally comprising the families Lamprophiidae and Elapidae. Advanced genomic sequence studies, however, have found lamprophiids to be paraphyletic in respect to elapids. In describing the subfamily Cyclocorinae, Weinell et al. (2017) suggested some or all subfamilies of Lamprophiidae should be reevaluated at full family status as a way to prevent the alternative, which is classifying them as elapids. This was followed in later studies such as Zaher et al. (2019). The Reptile Database considers Elapoidea to be synonymous with its sister group Colubroidea (in contrast to other studies that distinguish between both), as it does not recognize the division of Colubridae into multiple families that comprise Colubroidea, and thus instead considers Colubroidea to be composed of Colubridae + the multiple families comprising Elapoidea. Below is the phylogeny of Elapoidea after Weinell et al. ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamprophiidae
The Lamprophiidae are a family of snakes found throughout much of Africa, including the Seychelles. There are 89 species as of July 2022. Biology Lamprophiids are a very diverse group of snakes. Many are terrestrial but some are fossorial (e.g. '' Amblyodipsas'') or semi-aquatic (e.g. '' Lycodonomorphus''). Some are fast-moving (e.g. '' Psammophis'') whereas others are slow (e.g. '' Duberria''). They are found in deserts, grasslands, tropical forests and mountains. Together they feed on mammals, birds, reptiles, amphibians, fish, and invertebrates. Some species use constriction to subdue their prey (e.g. '' Boaedon''). When other snake families were formerly included within the Lamprophiidae, they were considered even more diverse in biology, although this is now known to not be the case. Most species are oviparous. Classification Most lamprophiids were historically considered to be members of the subfamily Lamprophiinae in the family Colubridae. The following classification ...
