Researchers blame lack of experts, funds and resources for the long `shelf life' of all the new species.

If the reports of the November 20th issue of the Cell Press journal Current Biology are studied, one will find that there are several worlds' most unfamiliar species that are still waiting on museum shelves for their chance to get described and presently doing nothing but just collecting dust.

Yes, the report has clearly revealed that on an average a newly collected species is described in approx 20 years or even more sometimes and this period has been stated as the species' "shelf life" for which experts blame nothing else but lack of experts, funds and resources that are must to do such jobs.

"Species new to science are almost never recognized as such in the field", says Mr. Benoit Fontaine of Muséum National d'Histoire Naturelle in Paris. "Our study explains why it often happens that we describe species which were collected alive decades ago and which can be extinct now -- just as astronomers study the light of stars which do not exist anymore".

The professional has explained that there are several species that are rare and are represented in collections by a single specimen but the problem occurs when Taxonomists prefer waiting for more specimens of new species to describe it, which results in nothing but increased move of things to the world's museums and herbaria.
