Scientist believed to be killed by a great white shark
An Australian college student was attacked by a shark during a science experiment on Glenelg beach and is believed to be dead.
The Melbourne Herald-Sun reports the victim was collecting fish eggs with other scientists from Adelaide University when members saw what appeared to be a great white shark.
They managed to get one researcher out of the water but not the unnamed man, who is said to be in his 20s.
Police haven't' found a body but have recovered the man's oxygen tank and life vest.
The attack was miles from the beach where an 18-year-old was killed by a shark in December.
