The Italian Coast Guard on Friday released underwater images of a migrant boat that sank near the island of Lampedusa on June 30.
The packed, 8-metre (25-foot) boat capsized just as coast guard rescue crews were arriving, and seven bodies were soon pulled from the sea, while 46 people were rescued.
The death toll from the sinking rose to 16 late on Thursday, after the Italian coast guard said that another nine bodies had been spotted in or near the wreck of the wooden fishing vessel.
A coast guard statement said an underwater robot found the wreck some 90 metres (300 feet) deep.
Inside the wreckage, one body was spotted while those of eight other migrants were located nearby on the seabed.
