Hi all. How would one go about creating a squid arm in fusion 360?

I’ve tried doing a path with a pipe for starters. looks ok, but one end should be thick and the other end should end in a very thin shape. I can’t really find out how to transform the pipe.

The suction cups i can create on the surface of the arm/pipe by splitting up the surface with a 2d drawing, and then copy those objects along the pipe’s path. That sort of works but its the thickness of the pipe that’s hard. Any suggestions or other approaches i should take?

Here’s some squid arms for reference: https://www.google.dk/search?q=squid+tentacles&safe=off&tbm=isch&tbo=u&source=univ&sa=X&sqi=2&ved=0ahUKEwjWgMr4j47VAhXRa5oKHYpGAQYQsAQIPg&biw=1366&bih=662
