These designs were made as part of my Marine Sciences final project in college. The task was to pick a topic on marine culture and create a presentation about it to supposedly share with high school students. I designed around a "campaign" to save loggerhead sea turtles including posters, shirt designs, and infographics for my presentation.
Loggerheads commonly mistake plastic floating in the sea as jellyfish, which is one of their usual preys so clean up after yourself on the beach. Don't litter and pick up trash if you happen upon it. Keeping clean isn't only good for loggerheads and other marine creatures but for yourself as well.
