El vertebrado más pequeño del mundo

ghhEl vertebrado más pequeño que se conocen hasta ahora, Paedocypris progenetica, perteneciente a la familia Cyprinidae (emparentado con la carpas). Se descubrió en un pantano de Sumatra, en la zona de Malasia.

Este pez sólo mide 7,9 milímetros de longitud; pese a su diminuto tamaño, posee unos alerones pélvicos con unos músculos excepcionalmente grandes que utiliza para agarrar a la hembra durante la copula. Los adultos tienen un cuerpo transparente, circunstancia que les da la apariencia de una larva.

Viven en pantanos de turba de aguas oscuras que presentan un nivel de acidez (pH 3), al menos cien veces superior al del agua de lluvia. Se pensaban que las ciénagas albergaban muy pocas especies de animales, aunque recientes investigaciones parecen demostrar que esos hábitat acoge a una amplia gama de seres que no se dan en otros lugares.

El descubrimiento de los peces tan pequeño y extraño destaca lo poco que sabemos acerca de la diversidad en nuestro planeta.
