During the 2-month fishing journey in early 2012, new graduate student Paul Clerkin has seen many strange sharks under 2,000m in the Indian Ocean.
This 'ghost' shark seems like a new species. It has large pectoral fins and lives very deep in the sea.
Another 'ghost' shark. This shark has a curved spine on its back, near its head.
Small cat shark, probably a new species.
This fishing boat caught more than 30 "fake" cat sharks. These large, pointed face sharks seem to be quite rare, but Clerkin thinks that is not exactly true, probably because we rarely catch in deep waters.
In the position of the teeth, these fish are replaced by hard, flat pieces of bone.
This shark is quite long, small, with an extremely strange mouth.
Another species of shark has yet to be named.
