Crocs' long walk home

Three homesick crocodiles in Australia have shocked experts by walking 250 miles back 'home' after being relocated.

The discovery was made after tracking devices were attached to the reptiles, reports The BBC.

Saltwater crocodiles caught near popular Australian beaches and rivers are often shipped to more remote areas.

But the policy of relocating rogue crocodiles will now be questioned - since it seems the animals have a strong homing instinct.

Researchers said the results of their study were "staggering".

"We often thought crocodiles tired very quickly but here we show very clearly that they are capable of moving long distances for days on end," added Professor Craig Franklin, from the University of Queensland.
