Creating a new D&D world, part 22

Not too too long ago, I purchased The Ultimate RPG Game Master's Worldbuilding Guide: Prompts and Activities to Create and Customize Your Own Game World by James D'Amato and it, and going whale watching, inspired me to create a new D&D world. So here we go! I'm going to use prompts from the book to begin crafting this world, but not all posts will be from there.

Here is how I imagine different species of humanoids in the world. Note that all have a similar lifespan of about 100 years, otherwise, you can trust D&D Beyond's descriptions (though feel free to ask me if you have questions):
