Scientists found a multicellular specie of animals the size of a grain that do not need oxygen to live.
These amazing creatures were found in the Mediterranean sea in the L’Atalante Basin were it's so salty theirs no oxygen. This is really amazing because this is the first multicellular animal that can breath without oxygen.At first scientist believed these were just dead animals. Because this is not normal seawater it does not contain oxygen. After scientists studied these animals they still can find out why they don't need oxygen.
This relates are unit about organisms and there surroundings. This specie clearly made an adaption to suit the water there living, they changed to be able to survive in a specific surrounding and habitat.
I found this article when searching for a current event. I enjoyed reading this article because I never imagined that there were animal that can live without oxygen. I chose this article because i related to the unit we are studying in class. These small animals are the first multicellular creature that can actually live without oxygen this is what truly amazed me.

Afraid of Its Own Fishy Reflection

Male Chichlids are a type of freshwater fish, that go to after fish who dare to cross there path. When some chichlids see there one reflection in a mirror aggressively. Although these situations look the same, there brain reacts differently. When scientists looked at the fish's hormones they didn't see a difference but when they looked at the brain there was a difference. When they looked at the fish's brain while looking in it's reflection they saw it was active in a place similar to amygdala. In a humans brain this is where you associate with fear.
This is affecting scientific knowledge, we are learning that some animals don't even know how there reflection looks like. The limitations in this article is that you can't see how fish actually react when they see there reflection. I had a question how don't they know there own reflection.
When I was searching for an article, the title of this article sounded strange but interesting at the same time. My attention was grabbed when I read how fish react to there own reflection. I learned that some animals react differently to there reflections. I believe this is reliable because it was tested out more then one time. I felt amazed that fish act so aggressively when they see there reflection.
