Thousands pay respect to Irwin

People from all over the world are remembering animal expert Steve Irwin who was killed on Monday.

Thousands of his fans went to his zoo in Australia on Monday to leave flowers and to pay their respects.

Mr Irwin, known as the Crocodile Hunter, died when he was stung in the chest by a fish called a stingray, while he was filming for a TV show.

It's thought he was swimming above one of the rays, which flicked its tail up because it felt threatened.

Stingrays are normally very peaceful animals, and this is a very unusual thing for them to do.
