Over the last few decades, scientists are in the process of rediscovery and research of 1,200 lost species that have not seen for more than 1,500 years. However, Global Wildlife Conservation launched a worldwide quest for the top 25 most wanted species that are found in 18 countries around the world.

Robin Moore, who led this Global Wildlife Conservation's project, believed that he is hopeful to find these top 25 lost species. According to him, the lost species includes a sea horse, a bat, a parakeet and a bee and all these were nowhere to find in more than 10 years.

Moore said that Global Wildlife Conservation will do their best to look for these top 25 lost species; in fact, his team will start looking for the pink-headed duck in Burman, which has been lost for about 68 years. Also, they are in search of the lost mammals and frogs but Moore, way back in 2010 launched "The Search For Lost Frogs," luckily his team were able to locate 2 out of 10 lost frogs and rediscovered 12 in a year, via Amphibians Specialist Groups.

Global Wildlife Conservation gave the five out of top 25 lost species they are looking for so that if there is someone that is willing to help for this worldwide quest they can work in cooperation with the team. The Namdapha flying squirrel, which has been missing for 36 years and the only evidence they have is the specimen found in India. Next, is the Syr Darya shovelnose sturgeon saw in Kazakhstan, 57 years ago.

Other species that are included in the top 25 lost species Global Wildlife Conservation is looking for are the Himalayan quail that has been missing for 141 years and speculated to be found in two places in India. Another one is the Scarlet harlequin frog, which has been lost for 36 years and the pink-headed duck.
