Un nuevo estudio revela que los pulpos son reactivos con todo su cuerpo a la luz, incluso en entornos de oscuridad, por una compleja respuesta evolutiva.<\/h4>\n\n\n\n

As?? como los pulpos tienen la capacidad de experimentar dolor emocional<\/strong> y duelos interiores complejos<\/strong>, parece ser que pueden percibir luz<\/strong> en toda la extensi??n de sus tent??culos. Incluso cuando se encuentran en un ambiente en perfecta oscuridad, sus brazos son capaces de detectar fuentes lum??nicas<\/strong>. ??sta es la raz??n.<\/p>\n\n\n\n

Una respuesta evolutiva<\/h2>\n\n\n\n

Este recurso es parte de un camino evolutivo extenso<\/strong>, de acuerdo con un estudio realizado en el Centro Acad??mico Ruppin de Israel. Si bien es cierto que los cefal??podos tienen uno de los sistemas neuronales m??s complejos<\/strong> entre los invertebrados, son notablemente incapaces<\/strong> de identificar en d??nde se encuentran en el espacio.<\/p>\n\n\n\n

Seg??n los cient??ficos que analizaron el caso, este intrincado comportamiento instintivo<\/strong> les ayuda a proteger sus tent??culos<\/strong> de los ataques de los depredadores cercanos, que de otra manera no podr??an percibir. Sorprendentemente, la regi??n m??s sensible<\/strong> es la punta de cada brazo.PUBLICIDAD<\/p>\n\n\n\n

Adem??s, los pulpos son capaces de reaccionar a la luz con todo su cuerpo. Su piel es una coraza con ??rganos colmados de pigmento conocidos como cromat??foros. <\/em>Estos ??rganos cambian de color cuando interact??an con la luz,<\/strong> y son responsables de las impresionantes capacidades de camuflaje<\/strong> de estos animales.<\/p>\n\n\n\n

Un ???efecto de luz pura???<\/h2>\n\n\n\n

Desde el laboratorio en donde se analiz?? este comportamiento, los bi??logos Tal Shomrat y Nir Nesher<\/strong> se dieron cuenta de un detalle m??s, que se convertir??a en el centro de su investigaci??n m??s adelante:<\/p>\n\n\n\n

Para el experimento, pusieron a un pulpo al interior de una pecera tapada con una lona negra opaca<\/strong>. De esta manera, lo entrenaron para que alcanzara trozos de pescado con sus tent??culos, ubicados en la parte superior del tanque.<\/p>\n\n\n\n

En el proceso, mientras el animal buscaba a ciegas un trozo de comida, los investigadores iluminaban el brazo del pulpo con una luz brillante en un momento al azar. El 84% de las veces que recibi?? este est??mulo<\/strong>, el pulpo retiraba r??pidamente su brazo. Esta respuesta sugiere que el pulpo es capaz de sentir y reaccionar a la luz con sus brazos, a??n cuando no la percib??a con los ojos<\/strong>.<\/p>\n\n\n\n

???A menudo sentimos el calor de la luz intensa, pero para el pulpo, este no es el caso???, dijo Neshir. ???En nuestros experimentos, verificamos cambios de temperatura y no hubo ninguno. El efecto es de luz pura???<\/strong>.<\/p>\n\n\n\n
