How to Add a Tube

Im new to blender. I downloaded a blend file of a snake. it is made of a tube mesh.
But i cant seem to find a tube in my mesh. There is only a cylinder. Lots of tutorials say Add->Mesh->Tube, but my blender does not seem to have it. Please help!!!

Use a Cylinder with “Cap Ends” instead. Tube and Cylinder are the same thing,
the Tube just got removed because it made no sense to have duplicates.

thx a lot!!!
