The trap started out from a box, that I subdivided and modified into shape. I then went into subpatch mode and made some places for the teeth. The teeth was made with a box, that I subdivided manually with the knife. The teeth was then rail cloned along a curve, matched with the trap. The cloned teeth was finally welded, point by point, into place. To make it less uniform i rotated and moved every teeth slightly in different directions.

I textured it by adding three bump procedural textures for the slightly different areas on the trap. I also added a gradient to get different texture closer to the mouth part (?).

The veins are just there for the background and to fill out some space. It's a simple rail cloned flat disc. I textured it with the same texture as the trap, but adjusted it slightly and removed some residual procedurals.

The worm was modeled from a stretched out box with 12 subdivisions. To get the ribs I smooth shifted every cylinder part in sub patch mode. The legs was made draft from a box in sub patch mode and rotated moved manually into place. While modeling, I also added some skelegons into it for moving the worm into place.

I textured it by making a simple cylindrical UV-texture in Photoshop for coloring. On top of the UV i placed two procedurals. I then added various procedurals and gradient to the other channels to get it more alive.

I sat up the worm on in the trap and converted the skelegons that I modeled into it, into bones. I then rotated the bones manually one by one into proper place.

The lighting was set up with one dome light above the meshes for simulating daylight and an area light coming from the camera. I also added a blurred out random generated image (actually just various filters into something green) for background to simulate some kind of macro photage.

I then rendered the scene with medium low AA, but enchanted with AS. No global illumination due to the dome- and area lighting.

Rendering time about 3 hours.
