18(2013) They are brightly coloured canivorous terrestrial
snails,but are facing extinction in their own limestone ecosystems of
Thailand due to mindless mining activity for the mineral.
one species of the snails is endemic to a particular range of
montains. They donot allow any other species of their ilk to invade
their jurisdiction – a unique trait in deed in the animal world.
snails are primarily herbivores and only a rare few groups like this
one are carnivorous. The animals come from several limestone areas
across the world, including some threatened by human exploitation,
especially by quarrying.
new species from the genusPerrottetia
described from north and northeastern Thailand. The species show
extraordinary endemism, with each of these colourful snails occurring
as "One Hill One Species."
is a very peculiar phenomenon where each one of these highly endemic
snails is specific and the only one inhabiting a certain mountain
range. They live in rock crevices, feeding on tinier snails, insect
larvae and some earthworms species.
beautiful animals are now at risk from extinction with the
destruction of limestone ecosystems. The study was published in the
open access journal ZooKeys.
ecosystems in the world are now being destroyed at an alarming rate.
This means we are losing biodiversity resources, a tendency
especially threatening for the hot spot areas like Thailand.
new research findings show that key terrestrial invertebrates, such
as several new bright carnivorous land snails are still persisting in
such areas and are being described even from the highly endangered
demonstrates that there are still remnants of some fundamental
ecosystem, which lives and is struggling for survival, a great
experience for humankind to learn.
three new Perrottetia species
exhibit distinct morphological characteristics, which make for a
great example for evolutionary studies in unstable environments,"

than 50% of limestone ecosystems in this region have been or still
are being destroyed. This astonishing case of biodiversity
persistence gives a valuable reason to put effort in the conservation
of this important world ecosystem. "

carnivorous terrestrial snails family Streptaxidae. //EOM//
