Hayden Panettiere took her love for the marine creatures up close, when she swam with sharks in Australia on Wednesday. The Heroes hottie, who has a special corner for marine wildlife, adorned her scuba gear to get a closer look of her sea- friends.

She took a dive with a few sea creatures at Ocean World in Manley, Sydney - and got a chance to feed the hungry sharks while they brushed up against her. Hayden is known for her passion about whales and is trying to rally support from the people of Australia urging them to sign the “Save the Whales Again!” petition at SocialVibe.com.

Hayden will be delivering the petition to the International Whaling Commission at their meeting this June in Madeira. Earlier in the day, press obligations kept her busy, as she visited “The Sunrise dawn Show” at the Channel Seven Studios in Martin Place.
