Scientific Name Philodina roseola
Location Lardero, La Rioja, Spain
Comments Es fácil encontrarlo en charcos pequeños o en lagunas y, si el agua se evapora, él, después de deshidratarse, puede volver a la vida como si nada...una y otra vez, siempre y cada vez que se secan los charcos en los que habita, Philodina pierde todo el agua de sus tejidos, se seca y cuando el agua vuelve, también él vuelve a la vida. Pero además, por si fuera poco, es uno de los organismos más resistentes a los rayos gamma que se conocen. Cualquier otro ser vivo quedaría abrasado y su material genético descompuesto ante una exposición a la radiación gamma. Sin embargo, Philodina roseola es capaz de restaurar los daños en el ADN que en otras especies serían irreversibles. Y, aún más...otra particularidad que le acerca casi a la inmortalidad y que está relacionada con su reproducción: es un organismo que se reproduce sexualmente sin necesidad del otro sexo. Los óvulos sin fecundar dan lugar a nuevos individuos, siempre hembras (partenogénesis). Pues aquí tenemos a nuestro superhéroe, discreto y casi desconocido, haciendo malabarismos con un grupito de algas en espera de que su charca se vuelva a secar. La muestra en la que se ha tomado la fotografía fue recolectada hace dos días junto al embalse de La Grajera, en Logroño. La foto se ha realizado a 200 aumentos empleando la técnica de contraste de interferencia. También en www.iesbatalladeclavijo.com/tablon/webvidaoculta/index.html y en www.fotolog.com/proyectoagua. ...junto con nuestro granito de arena por la paz en http://www.fund-culturadepaz.org/spa/03/cent03Articulos%202003/En_pie_de_paz.pdf

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
