When choosing between a list and a paragraph, the decision should be made by selecting a creature with the maximum number of skills and comparing the two options. A list might be problematic because it would take a long time to scroll through, and it takes longer to read. In a paragraph, the skills are read quickly, but the information is not as well retained. I personally lean towards the second option. Moreover, it can be improved by increasing the spacing between the skills, creating a kind of middle ground.
