Body Plans 2: Mollusks & Other Lophotrochozoans
It's easy to make aliens: take a person or a dog¸ slap some antennae on 'em¸ maybe some ooze and some spooky talons¸ and then put some random letters together in a nigh-unpronounceable combination.
As I said¸ it's easy to make aliens. What isn't easy is making them well.
Even when you're working hard to be creative¸ it can sometimes be hard to get out of the rut of familiarity¸ to go beyond four limbs and two eyes and venture into the realm of¸ well¸ the alien.
This series is about exploring the diversity of forms already lurking around us¸ breaking them down into short summaries so that you can use them as a jumping-off point for new forms of life and talking about some of the ways that they could be twisted around. By the time that you're done¸ nobody will guess that your original inspiration was a worm or a clam.
