Angler biologist Jeremy Wade has a hit show on Discovery Networks travelling around the world to catch and release some of the planets more extreme underwater critters.
It's a great job if you can get it.
The critter he is holding is fly fishing's Mount Everest, it is Hydrocynus goliath and to date few have actually caught one and lived to tell the tale.
For obvious reasons this critter is hard to catch (namely teeth) and the fact you'll find it in the Congo River Basin an area not known for friendly gastronomic flora, insects, rival militaristic rebel groups or even ease of travel.
Still, as far as freshwater predators go, this one is at the top of the list. Nice catch, great show.
