A model of an imagined/fictional male velociraptor created when we first practice using Blender, with some major internal (theorized) systems: digestive system, reproductive system,... some of which can be controlled. There is a Readme.txt included together with the model to show how the control can be performed. You can also adjust the Alpha setting to view the internal anatomy through the dinosaur's translucent skin.
The velociraptor model has 129 521 vertices, and when turned all subdivisions on, it has 399 557 vertices.
You can remove or replace any part of the model if you want to suit your purposes (Lighter file, non - nsfw, game uses, ...).
