Species inquirenda

Okay kiddo, do you remember those books with pictures of animals where you had to match them with their names? Well, sometimes scientists can't figure out which group an animal belongs to. They get confused because it looks like it could be in different groups, or they don't know enough about it to put it in a specific group. When this happens, they call it "species inquirenda," which means "species to be investigated." It's like saying, "I'm not sure what this animal is, so I need to do more research to figure it out." Scientists will keep studying the animal until they know enough to put it in the right group. So species inquirenda is like a puzzle that scientists need to solve by studying and learning more about animals.
