A trait is something we use to explain different aspects of an organism. When we are looking at an individual organism—it doesn’t matter what it is—we have four categories of traits. These traits can be: behavioral, morphological, and physical. One ability can affect more than one trait group. For example, a physical trait such as size or skin type might also affect certain behaviors 

How you measure a trait depends on the trait itself. If it’s something behavioral, which is hard to quantify, we have to do observations. However, if it’s something morphological, we can just do quantitative measurement. 

One thing I’ve never considered before this class was how traits shapes the ecosystem dynamics. Blue whales carry massive amounts of water and oxygen and nutrients with them, and when they release it through their blubbers, it helps with cycling these nutrients in the oceans. 

Did you know that…?

Octopi have 3 hearts and blue blood. The morphological trait comes from their blood carrying copper instead of iron, which needs more circulation in its body. So, 2 of the 3 hearts dont work while theyre swimming, so thats why most of the footage of these animals are crawling around. 

Another fact, an octopus has the ability to give 3 times more hugs than most of the animal kingdom!
