Xenophidion schaeferi, also known commonly as the Malayan spinejaw snake[2] or Schäfer's spiny-jawed snake,[1] is a species of snake in the monotypic family Xenophidiidae.[2] The species is endemic to Malaysia.

Etymology

The specific name, schaeferi is in honor of German herpetologist Christian Schäfer who collected the holotype.[3]

Geographic range

X. schaeferi is found in the Malaysian state of Selangor, in western Peninsular Malaysia.[1][2]

Habitat

The preferred natural habitat of X. schaeferi is forest.[1]

Reproduction

X. schaeferi is oviparous.[2]

DNA sequence divergence of sibling species

In the genus Xenophidion, there is one sister species, X. acanthognathus. Molecular analyses of a new specimen of X. acanthognathus reveal that it only differs from the holotype of X. schaeferi by a minimum sequence divergence of 0.27%.[4]

gollark: Yes, but it involves less boilerplate.

gollark: Just use `collections.namedtuple` or whatever it is.

gollark: ```pythonclass ThisIsUseless: def __init__(self, why): print("Honestly, you should just use collections.named_tuple instead") def not_really(): print("Just define them as separate functions")```

gollark: Or is it namedtuple? Something like that.
