Presentación

Con este blog pretendo mostrar los últimos acontecimientos científicos, para que conozcamos lo que puede ser hecho por los científicos en este momento, y sus últimos descubrimientos, y al mismo tiempo ofrecer curiosidades, divertidas o simplemente extrañas, del ámbito de la ciencia. Y siempre, intentaré, con un lenguaje accesible a todos, sin grandes complicaciones. Espero que os guste. No olvideis que el cuerpo al blog se lo doy yo, pero la vida, el movimiento, sólo vuestros comentarios pueden dárselo. Cualquier cosa que queráis decirme, no lo dudéis, aquí estoy.

Mimetismo (I) - Para comer o para no ser comido






















Mimetismo, camuflaje, métodos utilizados por los animales para confundirse con su medio ambiente. No son lo mismo, lo explicaré en una próximo post sobre este tema.

Son de manera general, de todos modos, varios tipos de procedimiento con el fin de engañar a otros, de no ser descubiertos: Cambios de color, aspecto físico especial, actitudes...

El motivo del engaño es también variable, puede ser esconderse del depredador como disfrazarse para acercarse a la presa (o que se acerque ella), o incluso como ayuda en el proceso reproductor, como las plantas que imitan hembras de insectos para que los machos se acerquen y ayuden así en la polinización.

Este post lo dedico a presentar algunas fotografías que ejemplifican estas situaciones, siempre curiosas de observar. Explicaré algo más en el próximo dedicado a este tópico.

La rana en realidad ta escondia

Pregunta: es verdad que los camaleones si los pones encima de algo rojo les da un yuyu?

Aureus | 13 de febrero de 2009, 1:05  

Si, tienes razón en lo de la rana.
No, hasta donde llegan mis conocimientos con los camaleones, creo que no les da un yuyu, o por lo menos no uno grave. Pero algo hay. Parece que si tienen problemas para imitar este color, y por lo tanto no se camuflan, lo notan, y se estresan. O sea, se ponen nerviosos, nada más.
