This sea slug looks like a leaf because it contains chlorophyll-rich plant structures called chloroplasts, extracted from algae it eats. Now researchers led by Texas A&M say Elysia chlorotica has also acquired from the algae at least one gene necessary for photosynthesis—a first among animals. The slug can photosynthesize on its own for months.

Please tell me if it was your publication that presented a story on gourds within the last 3-4 months. I think the title was something like_____________gourd capital of the world. Thank you
