Pic: Big-eye tuna poses for naked snap with Helena Bonham Carter

Apparently there's a valid reason.

We've known for quite some time that Helena Bonham Carter embraces the weird and wonderful with consummate ease. She is the living embodiment of quirky. From her strange films directed by former husband Tim Burton and obviously starring opposite Johnny Depp, she's always had a whiff of the eccentrics off her. This photo shoot she did with a big fish is right up there with the most bizarre things she has ever done. She did it to support an initiative for the Blue Marine Foundation, who are trying to protect endangered species, such as the Big-eye tuna. So fair play to her.

Important to Understand why Helena's pictures are drawing attention http://t.co/vhx43IulAu@Bluemarinef#GBoceanspic.twitter.com/Z1srVOFLFk — Fishlove.co.uk (@fishlove2015) February 11, 2015

We're looking forward to the next instalment in the series featuring her pal Mr Depp as he has fish-fingers strapped to his hands in a photo-shoot simply called: Edward Fishfingerhands.
