Physella acuta<\/em><\/strong> (Draparnaud, 1805)            <\/em><\/strong>           MBCN31073 <\/p>

Physella acuta es un caracolillo de agua dulce originario de Am\u00e9rica del Norte, actualmente considerado una especie ex\u00f3tica invasora que se ha establecido en todos los continentes excepto la Ant\u00e1rtida. Su concha, que puede alcanzar los 12 mm de altura, es fina, transl\u00facida y de color marr\u00f3n amarillento, tiene forma de espiral que se enrolla en sentido contrario a las agujas del reloj y presenta un \u00e1pice puntiagudo. El cuerpo es de color gris parduzco; el manto presenta manchas doradas, que se pueden ver a trav\u00e9s de la concha. Los ojos se encuentran en la base de dos tent\u00e1culos c\u00f3nicos y finos, de color gris transl\u00facido. Puede vivir en una ampl\u00edsima diversidad de ambientes, incluyendo aguas muy degradadas con gran cantidad de materia org\u00e1nica y poco ox\u00edgeno, ya que puede salir a la superficie para respirar. Adem\u00e1s, esta especie puede autofecundarse, de manera que un solo individuo puede dar lugar a una poblaci\u00f3n entera. Cuando se ha establecido en un nuevo lugar, Physella acuta suele competir con las poblaciones aut\u00f3ctonas de caracolillos de agua dulce, provocando su r\u00e1pido declive o incluso su extinci\u00f3n. Se alimenta de algas y plantas acu\u00e1ticas, as\u00ed como de otra materia vegetal muerta.<\/p>
