Just looked it up on map editor:

The Spine Crawler works by firing an invisible missile (which the tentacle follows).

The "launch missile" effect of the weapon chooses between two movers. One for short range, the other for long range.

I don't think this can be dodged because the Launch Missile ability is "target unit", not "target unit/point". Its guidance is "throw" with no parabola or hook, and it has a timeout of 30 seconds, so I could be wrong.

The short range version has 10 acceleration, 20 max speed, and a rotation speed of 1 (not sure what that is).

The long range version has 140 acceleration and 200 speed, and a rotation speed of 12 (not sure what that is).

I believe that if it is possible to dodge a spine crawler, then you need something roughly 5 times as fast as a Phoenix that can accelerate to maximum velocity almost instantaneously, and you need to start within 3 range of the crawler.
