Here's a short video shot in Lembeh Strait, Indonesia, with a Canon 7D in a Nauticam underwater housing with 60mm macro lens and INON Underwater Micro Semi-Fisheye Relay Lens UFL-MR130 EFS60 (AKA "bug eye" or "insect eye") -- effectively, and underwater endoscope. The INON bug eye lens produces images with a perspective otherwise impossible to achieve -- like seeing the macro world from a small critter's perspective!
Here's a shot of the rig I used:
It looks like an insecticon, no?
