Naomi Watts, Liev Schreiber and Rosario Dawson have taken part in a new public service announcement (Psa) to promote the importance of marine conservation.

The stars, alongside Slash, Ted Danson and Christopher Walken, appear in the promo for the Turtle Conservancy, handling the shelled creatures while extolling their virtues.

The Psa's release coincided with Earth Day, a celebration of protecting the environment, on 22 April (14).

The Turtle Conservancy oversees a breading program to help boost the numbers of the most endangered species.
