Etymology

The specific name ''latastei'', is in honor of Boscà's French colleague,
herpetologist Herpetology (from Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians (gymnophiona)) and rept ...
Fernand Lataste Fernand Lataste (1847 - 1934) was a French zoologist and herpetologist born in Cadillac, Gironde. From 1880 to 1884 he collected reptiles and amphibians in North Africa (Algeria, Tunisia and Morocco), publishing ''"Les missions scientifiques de ...
, who would a year later return him the honor, by naming after him a discovery of his own, Boscá's newt (''Lissotriton boscai'' ).


Description

''V. latastei'' grows to a maximum total length (including tail) of about 72 cm (28.3 in), but usually less. It is grey in colour, has a triangular head, a "horn" on the tip of its nose, and a zig-zag pattern on its back. The tip of the tail is yellow.


Behaviour

''V. latasei'' can be seen day or night but is usually hidden under rocks. The yellow tip of the tail is possibly used to lure prey.

Conservation status

The species ''V. latastei'' was classified as Near Threatened (NT) according to the
IUCN The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natu ...
Red List of Threatened Species (v3.1, 2001), and from 2008 is recognised as Vulnerable (VU). It is listed as such because it is probably in significant decline (but likely at a rate of less than 30% over ten years) due to widespread habitat loss and persecution throughout much of its range, thus making the species close to qualifying for Vulnerable. Further population reduction is expected, but is not likely to exceed 30% over the next 10 years, but localized extinctions in parts of its range are possible (e.g., Tunisia, Spain). It is also listed as a strictly protected species (Appendix II) under the
Berne Convention The Berne Convention for the Protection of Literary and Artistic Works, usually known as the Berne Convention, was an international assembly held in 1886 in the Swiss city of Bern by ten European countries with the goal to agree on a set of leg ...
