But she adds that "at the same time that these species are telling us that they are resilient, it is also usual that when a specimen of one of these species reappears, they are usually very small, fragile, localized populations and that the conservation efforts must be very large to ensure their permanence on the planet". "The phenomenon of Lazarus Species is extremely interesting for science because when finding these new organisms, the hope that many species, critically endangered and that we assume will disappear very soon, may be more resilient than what they are believed to be returns", says biologist Gina Gómez Junco of the international organization ProCAT.
