Unlikely. An approximation, perhaps, but morphology does not follow such precise specifications, and as a rule of thumb it is particularly futile when you could just measure the animal's height then and there. Unless you are working from an elephant foot's wastebasket, in which case: shame on you. It's not a complete set of instructions anyway, does it mean the two front feet, the two back, a front and a back, double a single foot...?
This is
Myrianida pachycera, a polychaete worm. As you can see, the reproductive strategy of one of its forms is the asexual budding off of new worms from a continuously growing chain of worm children.
