Judi Dench, Fiona Shaw and Julie Christie are among six British stars to strip off for new photos designed to raise awareness of overfishing.
The snaps, to mark World Oceans Day on June 8, were taken for the Fishlove campaign and echo a similar picture of Helena Bonham-Carter released this year.
Like Bonham-Carter, who posed with a 27kg tuna, each of the actors involved covers her modesty with marine animals, in Dench's case, a lobster. Zoe Wanamaker, Tamla Kari and Kathy Lette have also posed.
The campaign highlights the devastation wrought by overfishing and aims to encourage shoppers to buy only sustainably caught fish.
Speaking to the Sunday Times, Dench, 80, revealed she opted for a lobster because she "has a passion for them".
