If you’re an endangered species, it helps to be cute, spectacular, or
otherwise unique. Unpopular species don’t make it to “the list,” argues
botanist Mark Burgman of the University of Melbourne.

The snail is evidently popular in Tasmania, which includes 200 species
of Hydrobiid snails on its list of 650 threatened species.

Burgman believes that scientific bias toward listing these
more-interesting species, regardless of the threats to their survival,
may condemn a substantial proportion of the world’s less-interesting or
less well-known plants and animals to extinction.
