Anderson, 45, posed topless for the shoot with an eel strategically covering her chest.
The former "X-Files" star has been very active on Twitter, where she has nearly 80,000 followers, in broadcasting her various charities and causes -- Fishlove included.
"Amazing animals that live in the deep ocean are being systematically destroyed by massive fishing nets that catch or crush everything in their path," claims the petition that Anderson supports. "But in days, the European Parliament could vote to protect one of the world’s most precious deep-sea habitats - and we need to give them the public mandate to do it."
"On December 10th Members of the European Parliament can vote to ban the most destructive forms of deep-sea fishing in the Northeast Atlantic ... Let’s make sure they have what they need before this historical vote! If we come together right now to raise our voices - we can ensure one of the most wonderful ocean habitats in the world is protected. Sign the petition right now and share this with everyone."
