ScienceDaily (Oct. 13, 2011) — Thanks to Hollywood, piranhas have a bad reputation and it would be a brave scientist that chose to plunge their hand into a tank of them. But that didn't deter Sandie Millot, Pierre Vandewalle and Eric Parmentier from the University of Liège, Belgium. "You just have to pick them up and they make sounds," says Parmentier. However, it wasn't clear when and why piranhas produce sounds naturally. Intrigued by fish acoustic communication and the mechanisms that they use to generate sound, the team monitored the behaviour of small groups of captive red-bellied piranhas and publish their discovery that the fearsome fish have a repertoire of three combative sounds.
What I understand is that the piranha, Besides of bites, they make sounds to communicate with other animals. That made a great impact to science because the message of the world to us is that many secrets have in many animals and even humans that still humans doesn't know and by time the people is going to find out.
I am not really interested, I am shocked because with this article, the people can concluded that the many natural phenom exist and the science doesn't know. And also I conclued that the piranha has many things that we don't know and soon, we will find out.
I connection is that I want to be a marine biology and reading this article, I can think that working as a biologist means challenge, secrets and phenomenom. And this motivate me to improve and read more about fish not only to improve knowledge, but also as a real biologist who his purpose is to improove the world.
This is an article about:
Environment: Because it is talking about animal and everything that has relation with natural resources, it is called environment.
