Yesterday, I saw one of the weirdest and coolest sea slugs I've ever seen and it was in New Hampshire. This is Elysia chlorotica, a slug that eats algae and steals its chloroplasts to use for photosynthesis. Yes, this slug is solar powered! I saw this species back in 2022 at the same site, but this time there were literally hundreds of them! So cool. Many more pictures to come.
