Foto de un tiburón comiéndose a otro

This is a picture of a shark eating another shark. That is all.

sharkeatssharkIt was just going to be another day of shark monitoring for the researchers at the University of Delaware’s ORB LAB. Among other tasks, the group keeps track of shark populations in the ocean, catching and releasing the large predators. And this time, they caught two for the price of one. Write the researchers on their Facebook page:

We caught one large female on our first line Friday, but we were not expecting to catch her like this! This unlucky smooth dogfish couldn’t resist the menhaden used as bait and unfortunately fell victim to one of the top predators in the bay. The dogfish was about 3 feet long and completely swallowed by the sand tiger shark.

dogfish: cazón

sand tiger shark: tiburón toro

Un pulpo que vive en una botella de cristal

El siguiente pulpo encontró una botella de cristal, probablemente de cerveza, en el fondo del mar y la convirtió en su casa. El vídeo tiene su valor porque podemos ver cómo el pulpo es capaz de darle forma a su cerebro para que pase por la boca de la botella como si nada.

Una vez fuera de la botella, el tamaño de su cerebro vuelve a la normalidad rápidamente junto con un cambio de color del propio pulpo, lo que pone de manifiesto, sin duda, el fantástico animal que son los pulpos.
