Miley's little sister stars in gruesome new anti-dissection campaign

Miley Cyrus' little sister Noah is the star of a hard-hitting new PETA ad, in which she appears to rip open her chest to reveal her organs.

While sibling Miley has made a name for herself by stripping down for photoshoots, selfies and videos, 15-year-old Noah has gone one step further in a peta2 campaign aimed at putting an end to classroom dissection.

In the gruesome new ad for the animal rights group's youth division, the pale teenager plays dead on a metal table with her chest cut open, exposing her innards.

Releasing the shocking image on Wednesday (08Apr15), a PETA spokesman writes, "Every year, more than 10 million animals are dissected in secondary school and college science classes. Most of them come from biological supply houses that sell cats obtained from animal shelters, fetal piglets cut from the wombs of pigs killed in slaughterhouses, and frogs who are taken from the wild.

"Studies have repeatedly shown that virtual dissection is more effective in teaching biology than cutting up dead animals."

In video footage from the shoot posted online, Noah says, "If you feel weird dissecting something, say, 'No'. I would totally say, 'I'm not cutting into this animal.'

"My friend had to do that for her college program to be a vet and she had to cut the tail off a lamb and a pig and dissect a cow. That's terrible. I would never wanna do that."
