Answer 1

Here, not all people have the meaning of life, but you are talking about worms!
You can do it in any programming language.

Answer 2

this is called - computer modeling and visualization
make it programmers-engineers
for this you need to study for several years
and there is not a "detailed copy of the real" but only a model of the nervous and muscular systems

Answer 3

AI + 3D-"engine", in fact, that worm is no different from an ordinary modern game with computer AI (AI), it is interesting only because it is a "digitization" of the analogue nervous system of a living worm, a non-trivial task of reverse engineering, for this you need a worm "debugger", that is, special equipment that acts as a voltmeter, oscilloscope, ohmmeter, etc., connected to different points of the worm's nervous system, and of course, a microscope.
