Mystery of the dead crocodiles solved
Scientists believe that they might have finally cracked the mystery of the deaths of thousands of baby crocodiles
in captivity in the Top End.//
Eye and throat disease had killed the young farmed crocodiles
at four of the Top End's five crocodile farms in recent past weeks.

Dwarf crocodiles split into three species
You'd think that if scientists were to discover a new species, it would be in some remote, uncharted tropical forest, not a laboratory in New York.
