Boy band Union J have teamed up with peta2, PETA's youth division, to star in its latest anti SeaWorld campaign.

The four band members are seen squeezing into a bath, to promote how small tanks are for orcas in SeaWorld, next to the words 'Imagine spending your entire life in a small bathtub. Orcas deserve to swim free. Boycott SeaWorld'. Singer Josh Cuthbert commented 'We're not going to stop until every dolphin, every orca, and all the other amazing animals are free in sea sanctuaries'.
